Please use .Xr pfctl 8 instead. -.Pp -To ease configuration, rules can be put into a file which is -processed using -.Nm -as shown in the first synopsis line. -An absolute -.Ar pathname -must be used. -The file -will be read line by line and applied as arguments to the -.Nm -utility. -.Pp -Optionally, a preprocessor can be specified using -.Fl p Ar preproc -where -.Ar pathname -is to be piped through. -Useful preprocessors include -.Xr cpp 1 -and -.Xr m4 1 . -If -.Ar preproc -doesn't start with a slash -.Pq Ql / -as its first character, the usual -.Ev PATH -name search is performed. -Care should be taken with this in environments where not all -file systems are mounted (yet) by the time -.Nm -is being run (e.g. when they are mounted over NFS). -Once -.Fl p -has been specified, optional -.Fl D -and -.Fl U -specifications can follow and will be passed on to the preprocessor. -This allows for flexible configuration files (like conditionalizing -them on the local hostname) and the use of macros to centralize -frequently required arguments like IP addresses. -.Pp -The -.Nm -code works by going through the rule-list for each packet, -until a match is found. -All rules have two associated counters, a packet count and -a byte count. -These counters are updated when a packet matches the rule. -.Pp -The rules are ordered by a -.Dq line-number -from 1 to 65534 that is used -to order and delete rules. -Rules are tried in increasing order, and the -first rule that matches a packet applies. -Multiple rules may share the same number and apply in -the order in which they were added. -.Pp -If a rule is added without a number, it is numbered 100 higher -than the previous rule. -If the highest defined rule number is -greater than 65434, new rules are appended to the last rule. -.Pp -The delete operation deletes the first rule with number -.Ar number , -if any. -.Pp -The list command prints out the current rule set. -.Pp -The show command is equivalent to `ip6fw -a list'. -.Pp -The zero operation zeroes the counters associated with rule number -.Ar number . -.Pp -The flush operation removes all rules. -.Pp -Any command beginning with a -.Sq # , -or being all blank, is ignored. -.Pp -One rule is always present: -.Bd -literal -offset center -65535 deny all from any to any -.Ed -.Pp -This rule is the default policy, i.e., don't allow anything at all. -Your job in setting up rules is to modify this policy to match your -needs. -.Pp -The following options are available: -.Bl -tag -width flag -.It Fl a -While listing, show counter values. See also -.Dq show -command. -.It Fl f -Don't ask for confirmation for commands that can cause problems if misused -(ie; flush). -.Ar Note , -if there is no tty associated with the process, this is implied. -.It Fl q -While adding, zeroing or flushing, be quiet about actions (implies '-f'). -This is useful for adjusting rules by executing multiple ip6fw commands in a -script (e.g. sh /etc/rc.firewall), or by processing a file of many ip6fw rules, -across a remote login session. If a flush is performed in normal -(verbose) mode, it prints a message. Because all rules are flushed, the -message cannot be delivered to the login session, the login session is -closed and the remainder of the ruleset is not processed. Access to the -console is required to recover. -.It Fl t -While listing, show last match timestamp. -.It Fl N -Try to resolve addresses and service names in output. -.El -.Pp -.Ar action : -.Bl -hang -offset flag -width 16n -.It Ar allow -Allow packets that match rule. -The search terminates. -Aliases are -.Ar pass , -.Ar permit , -and -.Ar accept . -.It Ar deny -Discard packets that match this rule. -The search terminates. -.Ar Drop -is an alias for -.Ar deny . -.It Ar reject -(Deprecated.) Discard packets that match this rule, and try to send an ICMPv6 -host unreachable notice. -The search terminates. -.It Ar unreach code -Discard packets that match this rule, and try to send an ICMPv6 -unreachable notice with code -.Ar code , -where -.Ar code -is a number from zero to 255, or one of these aliases: -.Ar noroute , -.Ar admin , -.Ar notneighbor , -.Ar addr , -or -.Ar noport , -The search terminates. -.It Ar reset -TCP packets only. -Discard packets that match this rule, -and try to send a TCP reset (RST) notice. -The search terminates -.Em ( "not working yet" ) . -.It Ar count -Update counters for all packets that match rule. -The search continues with the next rule. -.It Ar skipto number -Skip all subsequent rules numbered less than -.Ar number . -The search continues with the first rule numbered -.Ar number -or higher. -.El -.Pp -If the kernel was compiled with -.Dv IPV6FIREWALL_VERBOSE , -then when a packet matches a rule with the -.Dq log -keyword or a clear/resetlog is performed, a message will be logged to -.Xr syslogd 8 , -or, if that fails, to the console. If the kernel was compiled with the -.Dv IPV6FIREWALL_VERBOSE_LIMIT -option, then logging will cease after the number of packets -specified by the option are received for that particular -chain entry. -When this limit is reached, the limit and rule number will be logged. -Logging may then be re-enabled by clearing -the packet counter for that entry. -.Pp -The -.Xr syslogd 8 -logging and the default log limit are adjustable dynamically through the -.Xr sysctl 8 -interface. -.Pp -.Ar proto : -.Bl -hang -offset flag -width 16n -.It Ar ipv6 -All packets match. -The alias -.Ar all -has the same effect. -.It Ar tcp -Only TCP packets match. -.It Ar udp -Only UDP packets match. -.It Ar ipv6-icmp -Only ICMPv6 packets match. -.It Ar -Only packets for the specified protocol matches (see -.Pa /etc/protocols -for a complete list). -.El -.Pp -.Ar src -and -.Ar dst : -.Bl -hang -offset flag -.It Ar

See the -.Ar frag -option for details on matching fragmented packets. -.Pp -Rules can apply to packets when they are incoming, or outgoing, or both. -The -.Ar in -keyword indicates the rule should only match incoming packets. -The -.Ar out -keyword indicates the rule should only match outgoing packets. -.Pp -To match packets going through a certain interface, specify -the interface using -.Ar via : -.Bl -hang -offset flag -width 16n -.It Ar via ifX -Packet must be going through interface -.Ar ifX . -.It Ar via if* -Packet must be going through interface -.Ar ifX , -where X is any unit number. -.It Ar via any -Packet must be going through -.Em some -interface. -.It Ar via ipv6no -Packet must be going through the interface having IPv6 address -.Ar ipv6no . -.El -.Pp -The -.Ar via -keyword causes the interface to always be checked. -If -.Ar recv -or -.Ar xmit -is used instead of -.Ar via , -then the only receive or transmit interface (respectively) is checked. -By specifying both, it is possible to match packets based on both receive -and transmit interface, e.g.: -.Pp -.Dl "ip6fw add 100 deny ip from any to any out recv ed0 xmit ed1" -.Pp -The -.Ar recv -interface can be tested on either incoming or outgoing packets, while the -.Ar xmit -interface can only be tested on outgoing packets. -So -.Ar out -is required (and -.Ar in -invalid) whenever -.Ar xmit -is used. -Specifying -.Ar via -together with -.Ar xmit -or -.Ar recv -is invalid. -.Pp -A packet may not have a receive or transmit interface: packets originating -from the local host have no receive interface. while packets destined for -the local host have no transmit interface. -.Pp -Additional -.Ar options : -.Bl -hang -offset flag -width 16n -.It frag -Matches if the packet is a fragment and this is not the first fragment -of the datagram. -.Ar frag -may not be used in conjunction with either -.Ar tcpflags -or TCP/UDP port specifications. -.It in -Matches if this packet was on the way in. -.It out -Matches if this packet was on the way out. -.It ipv6options Ar spec -Matches if the IPv6 header contains the comma separated list of -options specified in -.Ar spec . -The supported IPv6 options are: -.Ar hopopt -(hop-by-hop options header), -.Ar route -(routing header), -.Ar frag -(fragment header), -.Ar esp -(encapsulating security payload), -.Ar ah -(authentication header), -.Ar nonxt -(no next header), and -.Ar opts -(destination options header). -The absence of a particular option may be denoted -with a -.Dq \&! -.Em ( "not working yet" ) . -.It established -Matches packets that have the RST or ACK bits set. -TCP packets only. -.It setup -Matches packets that have the SYN bit set but no ACK bit. -TCP packets only. -.It tcpflags Ar spec -Matches if the TCP header contains the comma separated list of -flags specified in -.Ar spec . -The supported TCP flags are: -.Ar fin , -.Ar syn , -.Ar rst , -.Ar psh , -.Ar ack , -and -.Ar urg . -The absence of a particular flag may be denoted -with a -.Dq \&! . -A rule which contains a -.Ar tcpflags -specification can never match a fragmented packet which has -a non-zero offset.

Please use .Xr pfctl 8 instead. -.Pp -The -.Nm -utility is the user interface for controlling the -.Xr ipfw 4 -firewall and the -.Xr dummynet 4 -traffic shaper. -.Pp -An -.Nm -configuration, or -.Em ruleset , -is made of a list of -.Em rules -numbered from 1 to 65535. -Packets are passed to -.Nm -from a number of different places in the protocol stack -(depending on the source and destination of the packet, -it is possible that -.Nm -is invoked multiple times on the same packet). -The packet passed to the firewall is compared -against each of the rules in the firewall -.Em ruleset . -When a match is found, the action corresponding to the -matching rule is performed. -.Pp -Depending on the action and certain system settings, packets -can be reinjected into the firewall at some rule after the -matching one for further processing. -.Pp -An -.Nm -ruleset always includes a -.Em default -rule (numbered 65535) which cannot be modified or deleted, -and matches all packets. -The action associated with the -.Em default -rule can be either -.Cm deny -or -.Cm allow -depending on how the kernel is configured. -.Pp -If the ruleset includes one or more rules with the -.Cm keep-state -or -.Cm limit -option, then -.Nm -assumes a -.Em stateful -behaviour, i.e. upon a match it will create dynamic rules matching -the exact parameters (addresses and ports) of the matching packet. -.Pp -These dynamic rules, which have a limited lifetime, are checked -at the first occurrence of a -.Cm check-state , -.Cm keep-state -or -.Cm limit -rule, and are typically used to open the firewall on-demand to -legitimate traffic only. -See the -.Sx STATEFUL FIREWALL -and -.Sx EXAMPLES -Sections below for more information on the stateful behaviour of -.Nm . -.Pp -All rules (including dynamic ones) have a few associated counters: -a packet count, a byte count, a log count and a timestamp -indicating the time of the last match. -Counters can be displayed or reset with -.Nm -commands. -.Pp -Rules can be added with the -.Cm add -command; deleted individually or in groups with the -.Cm delete -command, and globally (except those in set 31) with the -.Cm flush -command; displayed, optionally with the content of the -counters, using the -.Cm show -and -.Cm list -commands. -Finally, counters can be reset with the -.Cm zero -and -.Cm resetlog -commands. -.Pp -Also, each rule belongs to one of 32 different -.Em sets -, and there are -.Nm -commands to atomically manipulate sets, such as enable, -disable, swap sets, move all rules in a set to another -one, delete all rules in a set. These can be useful to -install temporary configurations, or to test them. -See Section -.Sx SETS OF RULES -for more information on -.Em sets . -.Pp -The following options are available: -.Bl -tag -width indent -.It Fl a -While listing, show counter values. -The -.Cm show -command just implies this option. -.It Fl c -When entering or showing rules, print them in compact form, -i.e. without the optional "ip from any to any" string -when this does not carry any additional information. -.It Fl d -While listing, show dynamic rules in addition to static ones. -.It Fl e -While listing, if the -.Fl d -option was specified, also show expired dynamic rules. -.It Fl f -Don't ask for confirmation for commands that can cause problems -if misused, -.No i.e. Cm flush . -If there is no tty associated with the process, this is implied. -.It Fl n -Only check syntax of the command strings, without actually passing -them to the kernel. -.It Fl N -Try to resolve addresses and service names in output. -.It Fl q -While -.Cm add Ns ing , -.Cm zero Ns ing , -.Cm resetlog Ns ging -or -.Cm flush Ns ing , -be quiet about actions -(implies -.Fl f ) . -This is useful for adjusting rules by executing multiple -.Nm -commands in a script -(e.g., -.Ql sh\ /etc/rc.firewall ) , -or by processing a file of many -.Nm -rules across a remote login session. -If a -.Cm flush -is performed in normal (verbose) mode (with the default kernel -configuration), it prints a message. -Because all rules are flushed, the message might not be delivered -to the login session, causing the remote login session to be closed -and the remainder of the ruleset to not be processed. -Access to the console would then be required to recover. -.It Fl S -While listing rules, show the -.Em set -each rule belongs to. -If this flag is not specified, disabled rules will not be -listed. -.It Fl s Op Ar field -While listing pipes, sort according to one of the four -counters (total or current packets or bytes). -.It Fl t -While listing, show last match timestamp (converted with ctime()). -.It Fl T -While listing, show last match timestamp (as seconds from the epoch). -This form can be more convenient for postprocessing by scripts. -.El -.Pp -To ease configuration, rules can be put into a file which is -processed using -.Nm -as shown in the last synopsis line. -An absolute -.Ar pathname -must be used. -The file will be read line by line and applied as arguments to the -.Nm -utility. -.Pp -Optionally, a preprocessor can be specified using -.Fl p Ar preproc -where -.Ar pathname -is to be piped through. -Useful preprocessors include -.Xr cpp 1 -and -.Xr m4 1 . -If -.Ar preproc -doesn't start with a slash -.Pq Ql / -as its first character, the usual -.Ev PATH -name search is performed. -Care should be taken with this in environments where not all -file systems are mounted (yet) by the time -.Nm -is being run (e.g. when they are mounted over NFS). -Once -.Fl p -has been specified, any additional arguments as passed on to the preprocessor -for interpretation. -This allows for flexible configuration files (like conditionalizing -them on the local hostname) and the use of macros to centralize -frequently required arguments like IP addresses. -.Pp -The -.Nm -.Cm pipe -and -.Cm queue -commands are used to configure the traffic shaper, as shown in the -.Sx TRAFFIC SHAPER (DUMMYNET) CONFIGURATION -Section below. -.Pp -If the world and the kernel get out of sync the -.Nm -ABI may break, preventing you from being able to add any rules. This can -adversely effect the booting process. You can use -.Nm -.Cm disable -.Cm firewall -to temporarily disable the firewall to regain access to the network, -allowing you to fix the problem. -.Sh PACKET FLOW -A packet is checked against the active ruleset in multiple places -in the protocol stack, under control of several sysctl variables. -These places and variables are shown below, and it is important to -have this picture in mind in order to design a correct ruleset. -.Bd -literal -offset indent - ^ to upper layers V - | | - +----------->-----------+ - ^ V - [ip_input] [ip_output] net.inet.ip.fw.enable=1 - | | - ^ V -[ether_demux] [ether_output_frame] net.link.ether.ipfw=1 - | | - +-->--[bdg_forward]-->--+ net.link.ether.bridge_ipfw=1 - ^ V - | to devices | -.Ed -.Pp -As can be noted from the above picture, the number of -times the same packet goes through the firewall can -vary between 0 and 4 depending on packet source and -destination, and system configuration. -.Pp -Note that as packets flow through the stack, headers can be -stripped or added to it, and so they may or may not be available -for inspection. -E.g., incoming packets will include the MAC header when -.Nm -is invoked from -.Cm ether_demux() , -but the same packets will have the MAC header stripped off when -.Nm -is invoked from -.Cm ip_input() . -.Pp -Also note that each packet is always checked against the complete ruleset, -irrespective of the place where the check occurs, or the source of the packet. -If a rule contains some match patterns or actions which are not valid -for the place of invocation (e.g. trying to match a MAC header within -.Cm ip_input() -), the match pattern will not match, but a -.Cm not -operator in front of such patterns -.Em will -cause the pattern to -.Em always -match on those packets. -It is thus the responsibility of -the programmer, if necessary, to write a suitable ruleset to -differentiate among the possible places. -.Cm skipto -rules can be useful here, as an example: -.Bd -literal -offset indent -# packets from ether_demux or bdg_forward -ipfw add 10 skipto 1000 all from any to any layer2 in -# packets from ip_input -ipfw add 10 skipto 2000 all from any to any not layer2 in -# packets from ip_output -ipfw add 10 skipto 3000 all from any to any not layer2 out -# packets from ether_output_frame -ipfw add 10 skipto 4000 all from any to any layer2 out -.Ed -.Pp -(yes, at the moment there is no way to differentiate between -ether_demux and bdg_forward). -.Sh SYNTAX -In general, each keyword or argument must be provided as -a separate command line argument, with no leading or trailing -spaces. Keywords are case-sensitive, whereas arguments may -or may not be case-sensitive depending on their nature -(e.g. uid's are, hostnames are not). -.Pp -In -.Nm ipfw2 -you can introduce spaces after commas ',' to make -the line more readable. You can also put the entire -command (including flags) into a single argument. -E.g. the following forms are equivalent: -.Bd -literal -offset indent -ipfw -q add deny src-ip 10.0.0.0/24,127.0.0.1/8 -ipfw -q add deny src-ip 10.0.0.0/24, 127.0.0.1/8 -ipfw "-q add deny src-ip 10.0.0.0/24, 127.0.0.1/8" -.Ed -.Sh RULE FORMAT -The format of -.Nm -rules is the following: -.Bd -ragged -offset indent -.Op Ar rule_number -.Op Cm set Ar set_number -.Op Cm prob Ar match_probability -.br -.Ar " " action -.Op Cm log Op Cm logamount Ar number -.Ar body -.Ed -.Pp -where the body of the rule specifies which information is used -for filtering packets, among the following: -.Pp -.Bl -tag -width "Source and dest. addresses and ports" -offset XXX -compact -.It Layer-2 header fields -When available -.It IPv4 Protocol -TCP, UDP, ICMP, etc. -.It Source and dest. addresses and ports -.It Direction -See Section -.Sx PACKET FLOW -.It Transmit and receive interface -By name or address -.It Misc. IP header fields -Version, type of service, datagram length, identification, -fragment flag (non-zero IP offset), -Time To Live -.It IP options -.It Misc. TCP header fields -TCP flags (SYN, FIN, ACK, RST, etc.), -sequence number, acknowledgment number, -window -.It TCP options -.It ICMP types -for ICMP packets -.It User/group ID -When the packet can be associated with a local socket. -.El -.Pp -Note that some of the above information, e.g. source MAC or IP addresses and -TCP/UDP ports, could easily be spoofed, so filtering on those fields -alone might not guarantee the desired results. -.Bl -tag -width indent -.It Ar rule_number -Each rule is associated with a -.Ar rule_number -in the range 1..65535, with the latter reserved for the -.Em default -rule. -Rules are checked sequentially by rule number. -Multiple rules can have the same number, in which case they are -checked (and listed) according to the order in which they have -been added. -If a rule is entered without specifying a number, the kernel will -assign one in such a way that the rule becomes the last one -before the -.Em default -rule. -Automatic rule numbers are assigned by incrementing the last -non-default rule number by the value of the sysctl variable -.Ar net.inet.ip.fw.autoinc_step -which defaults to 100. -If this is not possible (e.g. because we would go beyond the -maximum allowed rule number), the number of the last -non-default value is used instead. -.It Cm set Ar set_number -Each rule is associated with a -.Ar set_number -in the range 0..31. -Sets can be individually disabled and enabled, so this parameter -is of fundamental importance for atomic ruleset manipulation. -It can be also used to simplify deletion of groups of rules. -If a rule is entered without specifying a set number, -set 0 will be used. -.br -Set 31 is special in that it cannot be disabled, -and rules in set 31 are not deleted by the -.Nm ipfw flush -command (but you can delete them with the -.Nm ipfw delete set 31 -command). -Set 31 is also used for the -.Em default -rule. -.It Cm prob Ar match_probability -A match is only declared with the specified probability -(floating point number between 0 and 1). -This can be useful for a number of applications such as -random packet drop or -(in conjunction with -.Xr dummynet 4 ) -to simulate the effect of multiple paths leading to out-of-order -packet delivery. -.Pp -Note: this condition is checked before any other condition, including -ones such as keep-state or check-state which might have side effects. -.It Cm log Op Cm logamount Ar number -When a packet matches a rule with the -.Cm log -keyword, a message will be -logged to -.Xr syslogd 8 -with a -.Dv LOG_SECURITY -facility. -The logging only occurs if the sysctl variable -.Em net.inet.ip.fw.verbose -is set to 1 -(which is the default when the kernel is compiled with -.Dv IPFIREWALL_VERBOSE -) and the number of packets logged so far for that -particular rule does not exceed the -.Cm logamount -parameter. -If no -.Cm logamount -is specified, the limit is taken from the sysctl variable -.Em net.inet.ip.fw.verbose_limit . -In both cases, a value of 0 removes the logging limit. -.Pp -Once the limit is reached, logging can be re-enabled by -clearing the logging counter or the packet counter for that entry, see the -.Cm resetlog -command. -.Pp -Note: logging is done after all other packet matching conditions -have been successfully verified, and before performing the final -action (accept, deny, etc.) on the packet. -.El -.Ss RULE ACTIONS -A rule can be associated with one of the following actions, which -will be executed when the packet matches the body of the rule. -.Bl -tag -width indent -.It Cm allow | accept | pass | permit -Allow packets that match rule. -The search terminates. -.It Cm check-state -Checks the packet against the dynamic ruleset. -If a match is found, execute the action associated with -the rule which generated this dynamic rule, otherwise -move to the next rule. -.br -.Cm Check-state -rules do not have a body. -If no -.Cm check-state -rule is found, the dynamic ruleset is checked at the first -.Cm keep-state -or -.Cm limit -rule. -.It Cm count -Update counters for all packets that match rule. -The search continues with the next rule. -.It Cm deny | drop -Discard packets that match this rule. -The search terminates. -.It Cm divert Ar port -Divert packets that match this rule to the -.Xr divert 4 -socket bound to port -.Ar port . -The search terminates. -.It Cm fwd | forward Ar ipaddr Ns Op , Ns Ar port -Change the next-hop on matching packets to -.Ar ipaddr , -which can be an IP address in dotted quad format or a host name. -The search terminates if this rule matches. -.Pp -If -.Ar ipaddr -is a local address, then matching packets will be forwarded to -.Ar port -(or the port number in the packet if one is not specified in the rule) -on the local machine. -.br -If -.Ar ipaddr -is not a local address, then the port number -(if specified) is ignored, and the packet will be -forwarded to the remote address, using the route as found in -the local routing table for that IP. -.br -A -.Ar fwd -rule will not match layer-2 packets (those received -on ether_input, ether_output, or bridged). -.br -The -.Cm fwd -action does not change the contents of the packet at all. -In particular, the destination address remains unmodified, so -packets forwarded to another system will usually be rejected by that system -unless there is a matching rule on that system to capture them. -For packets forwarded locally, -the local address of the socket will be -set to the original destination address of the packet. -This makes the -.Xr netstat 1 -entry look rather weird but is intended for -use with transparent proxy servers. -.It Cm pipe Ar pipe_nr -Pass packet to a -.Xr dummynet 4 -.Dq pipe -(for bandwidth limitation, delay, etc.). -See the -.Sx TRAFFIC SHAPER (DUMMYNET) CONFIGURATION -Section for further information. -The search terminates; however, on exit from the pipe and if -the -.Xr sysctl 8 -variable -.Em net.inet.ip.fw.one_pass -is not set, the packet is passed again to the firewall code -starting from the next rule. -.It Cm queue Ar queue_nr -Pass packet to a -.Xr dummynet 4 -.Dq queue -(for bandwidth limitation using WF2Q+). -.It Cm reject -(Deprecated). -Synonym for -.Cm unreach host . -.It Cm reset -Discard packets that match this rule, and if the -packet is a TCP packet, try to send a TCP reset (RST) notice. -The search terminates. -.It Cm skipto Ar number -Skip all subsequent rules numbered less than -.Ar number . -The search continues with the first rule numbered -.Ar number -or higher. -.It Cm tee Ar port -Send a copy of packets matching this rule to the -.Xr divert 4 -socket bound to port -.Ar port . -The search terminates and the original packet is accepted -(but see Section -.Sx BUGS -below). -.It Cm unreach Ar code -Discard packets that match this rule, and try to send an ICMP -unreachable notice with code -.Ar code , -where -.Ar code -is a number from 0 to 255, or one of these aliases: -.Cm net , host , protocol , port , -.Cm needfrag , srcfail , net-unknown , host-unknown , -.Cm isolated , net-prohib , host-prohib , tosnet , -.Cm toshost , filter-prohib , host-precedence -or -.Cm precedence-cutoff . -The search terminates. -.El -.Ss RULE BODY -The body of a rule contains zero or more patterns (such as -specific source and destination addresses or ports, -protocol options, incoming or outgoing interfaces, etc.) -that the packet must match in order to be recognised. -In general, the patterns are connected by (implicit) -.Cm and -operators -- i.e. all must match in order for the -rule to match. -Individual patterns can be prefixed by the -.Cm not -operator to reverse the result of the match, as in -.Pp -.Dl "ipfw add 100 allow ip from not 1.2.3.4 to any" -.Pp -Additionally, sets of alternative match patterns ( -.Em or-blocks -) can be constructed by putting the patterns in -lists enclosed between parentheses ( ) or braces { }, and -using the -.Cm or -operator as follows: -.Pp -.Dl "ipfw add 100 allow ip from { x or not y or z } to any" -.Pp -Only one level of parentheses is allowed. -Beware that most shells have special meanings for parentheses -or braces, so it is advisable to put a backslash \\ in front of them -to prevent such interpretations. -.Pp -The body of a rule must in general include a source and destination -address specifier. -The keyword -.Ar any -can be used in various places to specify that the content of -a required field is irrelevant. -.Pp -The rule body has the following format: -.Bd -ragged -offset indent -.Op Ar proto Cm from Ar src Cm to Ar dst -.Op Ar options -.Ed -.Pp -The first part (proto from src to dst) is for backward -compatibility with -.Nm ipfw1 . -In -.Nm ipfw2 -any match pattern (including MAC headers, IPv4 protocols, -addresses and ports) can be specified in the -.Ar options -section. -.Pp -Rule fields have the following meaning: -.Bl -tag -width indent -.It Ar proto : protocol | Cm { Ar protocol Cm or ... } -.It Ar protocol : Oo Cm not Oc Ar protocol-name | protocol-number -An IPv4 protocol specified by number or name -(for a complete list see -.Pa /etc/protocols ) . -The -.Cm ip -or -.Cm all -keywords mean any protocol will match. -.Pp -The -.Cm { Ar protocol Cm or ... } -format (an -.Em or-block ) -is provided for convenience only but its use is deprecated. -.It Ar src No and Ar dst : Bro Cm addr | Cm { Ar addr Cm or ... } Brc Op Oo Cm not Oc Ar ports -An address (or a list, see below) -optionally followed by -.Ar ports -specifiers. -.Pp -The second format ( -.Em or-block -with multiple addresses) is provided for convenience only and -its use is discouraged. -.It Ar addr : Oo Cm not Oc Brq Cm any | me | Ar addr-list | Ar addr-set -.It Cm any -matches any IP address. -.It Cm me -matches any IP address configured on an interface in the system. -The address list is evaluated at the time the packet is -analysed. -.It Ar addr-list : ip-addr Ns Op Ns , Ns Ar addr-list -.It Ar ip-addr : -A host or subnet address specified in one of the following ways: -.Bl -tag -width indent -.It Ar numeric-ip | hostname -Matches a single IPv4 address, specified as dotted-quad or a hostname. -Hostnames are resolved at the time the rule is added to the firewall list. -.It Ar addr Ns / Ns Ar masklen -Matches all addresses with base -.Ar addr -(specified as a dotted quad or a hostname) -and mask width of -.Cm masklen -bits. -As an example, 1.2.3.4/25 will match -all IP numbers from 1.2.3.0 to 1.2.3.127 . -.It Ar addr Ns : Ns Ar mask -Matches all addresses with base -.Ar addr -(specified as a dotted quad or a hostname) -and the mask of -.Ar mask , -specified as a dotted quad. -As an example, 1.2.3.4/255.0.255.0 will match -1.*.3.*. -We suggest to use this form only for non-contiguous -masks, and resort to the -.Ar addr Ns / Ns Ar masklen -format for contiguous masks, which is more compact and less -error-prone. -.El -.It Ar addr-set : addr Ns Oo Ns / Ns Ar masklen Oc Ns Cm { Ns Ar list Ns Cm } -.It Ar list : Bro Ar num | num-num Brc Ns Op Ns , Ns Ar list -Matches all addresses with base address -.Ar addr -(specified as a dotted quad or a hostname) -and whose last byte is in the list between braces { } . -Note that there must be no spaces between braces and -numbers (spaces after commas are allowed). -Elements of the list can be specified as single entries -or ranges. -The -.Ar

Support for stateful -operation comes through the -.Cm check-state , keep-state -and -.Cm limit -options of -.Nm rules. -.Pp -Dynamic rules are created when a packet matches a -.Cm keep-state -or -.Cm limit -rule, causing the creation of a -.Em dynamic -rule which will match all and only packets with -a given -.Em protocol -between a -.Em src-ip/src-port dst-ip/dst-port -pair of addresses ( -.Em src -and -.Em dst -are used here only to denote the initial match addresses, but they -are completely equivalent afterwards). -Dynamic rules will be checked at the first -.Cm check-state, keep-state -or -.Cm limit -occurrence, and the action performed upon a match will be the same -as in the parent rule. -.Pp -Note that no additional attributes other than protocol and IP addresses -and ports are checked on dynamic rules. -.Pp -The typical use of dynamic rules is to keep a closed firewall configuration, -but let the first TCP SYN packet from the inside network install a -dynamic rule for the flow so that packets belonging to that session -will be allowed through the firewall: -.Pp -.Dl "ipfw add check-state" -.Dl "ipfw add allow tcp from my-subnet to any setup keep-state" -.Dl "ipfw add deny tcp from any to any" -.Pp -A similar approach can be used for UDP, where an UDP packet coming -from the inside will install a dynamic rule to let the response through -the firewall: -.Pp -.Dl "ipfw add check-state" -.Dl "ipfw add allow udp from my-subnet to any keep-state" -.Dl "ipfw add deny udp from any to any" -.Pp -Dynamic rules expire after some time, which depends on the status -of the flow and the setting of some -.Cm sysctl -variables. -See Section -.Sx SYSCTL VARIABLES -for more details. -For TCP sessions, dynamic rules can be instructed to periodically -send keepalive packets to refresh the state of the rule when it is -about to expire. -.Pp -See Section -.Sx EXAMPLES -for more examples on how to use dynamic rules. -.Sh TRAFFIC SHAPER (DUMMYNET) CONFIGURATION -.Nm -is also the user interface for the -.Xr dummynet 4 -traffic shaper. -.Pp -.Nm dummynet -operates by first using the firewall to classify packets and divide them into -.Em flows , -using any match pattern that can be used in -.Nm -rules. -Depending on local policies, a flow can contain packets for a single -TCP connection, or from/to a given host, or entire subnet, or a -protocol type, etc. -.Pp -Packets belonging to the same flow are then passed to either of two -different objects, which implement the traffic regulation: -.Bl -hang -offset XXXX -.It Em pipe -A pipe emulates a link with given bandwidth, propagation delay, -queue size and packet loss rate. -Packets are queued in front of the pipe as they come out from the classifier, -and then transferred to the pipe according to the pipe's parameters. -.Pp -.It Em queue -A queue -is an abstraction used to implement the WF2Q+ -(Worst-case Fair Weighted Fair Queueing) policy, which is -an efficient variant of the WFQ policy. -.br -The queue associates a -.Em weight -and a reference pipe to each flow, and then all backlogged (i.e., -with packets queued) flows linked to the same pipe share the pipe's -bandwidth proportionally to their weights. -Note that weights are not priorities; a flow with a lower weight -is still guaranteed to get its fraction of the bandwidth even if a -flow with a higher weight is permanently backlogged. -.Pp -.El -In practice, -.Em pipes -can be used to set hard limits to the bandwidth that a flow can use, whereas -.Em queues -can be used to determine how different flow share the available bandwidth. -.Pp -The -.Em pipe -and -.Em queue -configuration commands are the following: -.Bd -ragged -offset indent -.Cm pipe Ar number Cm config Ar pipe-configuration -.Pp -.Cm queue Ar number Cm config Ar queue-configuration -.Ed -.Pp -The following parameters can be configured for a pipe: -.Pp -.Bl -tag -width indent -compact -.It Cm bw Ar bandwidth | device -Bandwidth, measured in -.Sm off -.Op Cm K | M -.Brq Cm bit/s | Byte/s . -.Sm on -.Pp -A value of 0 (default) means unlimited bandwidth. -The unit must immediately follow the number, as in -.Pp -.Dl "ipfw pipe 1 config bw 300Kbit/s" -.Pp -If a device name is specified instead of a numeric value, as in -.Pp -.Dl "ipfw pipe 1 config bw tun0" -.Pp -then the transmit clock is supplied by the specified device. -At the moment only the -.Xr tun 4 -device supports this -functionality, for use in conjunction with -.Xr ppp 8 . -.Pp -.It Cm delay Ar ms-delay -Propagation delay, measured in milliseconds. -The value is rounded to the next multiple of the clock tick -(typically 10ms, but it is a good practice to run kernels -with -.Dq "options HZ=1000" -to reduce -the granularity to 1ms or less). -Default value is 0, meaning no delay. -.El -.Pp -The following parameters can be configured for a queue: -.Pp -.Bl -tag -width indent -compact -.It Cm pipe Ar pipe_nr -Connects a queue to the specified pipe. -Multiple queues (with the same or different weights) can be connected to -the same pipe, which specifies the aggregate rate for the set of queues. -.Pp -.It Cm weight Ar weight -Specifies the weight to be used for flows matching this queue. -The weight must be in the range 1..100, and defaults to 1. -.El -.Pp -Finally, the following parameters can be configured for both -pipes and queues: -.Pp -.Bl -tag -width XXXX -compact -.Pp -.It Cm buckets Ar hash-table-size -Specifies the size of the hash table used for storing the -various queues. -Default value is 64 controlled by the -.Xr sysctl 8 -variable -.Em net.inet.ip.dummynet.hash_size , -allowed range is 16 to 65536. -.Pp -.It Cm mask Ar mask-specifier -Packets sent to a given pipe or queue by an -.Nm -rule can be further classified into multiple flows, each of which is then -sent to a different -.Em dynamic -pipe or queue. -A flow identifier is constructed by masking the IP addresses, -ports and protocol types as specified with the -.Cm mask -options in the configuration of the pipe or queue. -For each different flow identifier, a new pipe or queue is created -with the same parameters as the original object, and matching packets -are sent to it. -.Pp -Thus, when -.Em dynamic pipes -are used, each flow will get the same bandwidth as defined by the pipe, -whereas when -.Em dynamic queues -are used, each flow will share the parent's pipe bandwidth evenly -with other flows generated by the same queue (note that other queues -with different weights might be connected to the same pipe). -.br -Available mask specifiers are a combination of one or more of the following: -.Pp -.Cm dst-ip Ar mask , -.Cm src-ip Ar mask , -.Cm dst-port Ar mask , -.Cm src-port Ar mask , -.Cm proto Ar mask -or -.Cm all , -.Pp -where the latter means all bits in all fields are significant. -.Pp -.It Cm noerror -When a packet is dropped by a dummynet queue or pipe, the error -is normally reported to the caller routine in the kernel, in the -same way as it happens when a device queue fills up. Setting this -option reports the packet as successfully delivered, which can be -needed for some experimental setups where you want to simulate -loss or congestion at a remote router. -.Pp -.It Cm plr Ar packet-loss-rate -Packet loss rate. -Argument -.Ar packet-loss-rate -is a floating-point number between 0 and 1, with 0 meaning no -loss, 1 meaning 100% loss. -The loss rate is internally represented on 31 bits. -.Pp -.It Cm queue Brq Ar slots | size Ns Cm Kbytes -Queue size, in -.Ar slots -or -.Cm KBytes . -Default value is 50 slots, which -is the typical queue size for Ethernet devices. -Note that for slow speed links you should keep the queue -size short or your traffic might be affected by a significant -queueing delay. -E.g., 50 max-sized ethernet packets (1500 bytes) mean 600Kbit -or 20s of queue on a 30Kbit/s pipe. -Even worse effect can result if you get packets from an -interface with a much larger MTU, e.g. the loopback interface -with its 16KB packets. -.Pp -.It Cm red | gred Ar w_q Ns / Ns Ar min_th Ns / Ns Ar max_th Ns / Ns Ar max_p -Make use of the RED (Random Early Detection) queue management algorithm. -.Ar w_q -and -.Ar max_p -are floating -point numbers between 0 and 1 (0 not included), while -.Ar min_th -and -.Ar max_th -are integer numbers specifying thresholds for queue management -(thresholds are computed in bytes if the queue has been defined -in bytes, in slots otherwise). -The -.Xr dummynet 4 -also supports the gentle RED variant (gred). -Three -.Xr sysctl 8 -variables can be used to control the RED behaviour: -.Bl -tag -width

maximum packet size, only used when queue -thresholds are in bytes (defaults to 1500, must be greater than zero). -.El -.El -.Sh CHECKLIST -Here are some important points to consider when designing your -rules: -.Bl -bullet -.It -Remember that you filter both packets going -.Cm in -and -.Cm out . -Most connections need packets going in both directions. -.It -Remember to test very carefully. -It is a good idea to be near the console when doing this. -If you cannot be near the console, -use an auto-recovery script such as the one in -.Pa /usr/share/examples/ipfw/change_rules.sh . -.It -Don't forget the loopback interface. -.El -.Sh FINE POINTS -.Bl -bullet -.It -There are circumstances where fragmented datagrams are unconditionally -dropped. -TCP packets are dropped if they do not contain at least 20 bytes of -TCP header, UDP packets are dropped if they do not contain a full 8 -byte UDP header, and ICMP packets are dropped if they do not contain -4 bytes of ICMP header, enough to specify the ICMP type, code, and -checksum. -These packets are simply logged as -.Dq pullup failed -since there may not be enough good data in the packet to produce a -meaningful log entry. -.It -Another type of packet is unconditionally dropped, a TCP packet with a -fragment offset of one. -This is a valid packet, but it only has one use, to try -to circumvent firewalls. -When logging is enabled, these packets are -reported as being dropped by rule -1. -.It -The -.Nm -filter list may not be modified if the system security level -is set to 3 or higher. -.El -.Sh PACKET DIVERSION -A -.Xr divert 4 -socket bound to the specified port will receive all packets -diverted to that port. -If no socket is bound to the destination port, or if the kernel -wasn't compiled with divert socket support, the packets are -dropped. -.Sh SYSCTL VARIABLES -A set of -.Xr sysctl 8 -variables controls the behaviour of the firewall and -associated modules ( -.Nm dummynet, bridge -). -These are shown below together with their default value -(but always check with the -.Xr sysctl 8 -command what value is actually in use) and meaning: -.Bl -tag -width indent -.It Em net.inet.ip.dummynet.expire : No

With -.Nm ipfw2 -you can put port specifications in rules matching all packets, -and the match will be attempted only on those packets carrying -protocols which include port identifiers. -.Pp -Finally, -.Nm ipfw1 -allowed the first port entry to be specified as -.Ar port:mask -where -.Ar mask -can be an arbitrary 16-bit mask. -This syntax is of questionable usefulness and it is not -supported anymore in -.Nm ipfw2 . -.It Or-blocks -.Nm ipfw1 -does not support Or-blocks. -.It keepalives -.Nm ipfw1 -does not generate keepalives for stateful sessions. -As a consequence, it might cause idle sessions to drop because -the lifetime of the dynamic rules expires. -.It Sets of rules -.Nm ipfw1 -does not implement sets of rules. -.It MAC header filtering and Layer-2 firewalling. -.Nm ipfw1 -does not implement filtering on MAC header fields, nor is it -invoked on packets from -.Cm ether_demux() -and -.Cm ether_output_frame(). -The sysctl variable -.Em net.link.ether.ipfw -has no effect there. -.It Options -In -.Nm ipfw1 , -the following options only accept a single value as an argument: -.Pp -.Cm ipid, iplen, ipttl -.Pp -The following options are not implemented by -.Nm ipfw1 : -.Pp -.Cm dst-ip, dst-port, layer2, mac, mac-type, src-ip, src-port. -.Pp -Additionally, the RELENG_4 version of -.Nm ipfw1 -does not implement the following options: -.Pp -.Cm ipid, iplen, ipprecedence, iptos, ipttl, -.Cm ipversion, tcpack, tcpseq, tcpwin . -.It Dummynet options -The following option for -.Nm dummynet -pipes/queues is not supported: -.Cm noerror . -.El -.Sh EXAMPLES -There are far too many possible uses of -.Nm -so this Section will only give a small set of examples. -.Pp -.Ss BASIC PACKET FILTERING -This command adds an entry which denies all tcp packets from -.Em cracker.evil.org -to the telnet port of -.Em wolf.tambov.su -from being forwarded by the host: -.Pp -.Dl "ipfw add deny tcp from cracker.evil.org to wolf.tambov.su telnet" -.Pp -This one disallows any connection from the entire cracker's -network to my host: -.Pp -.Dl "ipfw add deny ip from 123.45.67.0/24 to my.host.org" -.Pp -A first and efficient way to limit access (not using dynamic rules) -is the use of the following rules: -.Pp -.Dl "ipfw add allow tcp from any to any established" -.Dl "ipfw add allow tcp from net1 portlist1 to net2 portlist2 setup" -.Dl "ipfw add allow tcp from net3 portlist3 to net3 portlist3 setup" -.Dl "..." -.Dl "ipfw add deny tcp from any to any" -.Pp -The first rule will be a quick match for normal TCP packets, -but it will not match the initial SYN packet, which will be -matched by the -.Cm setup -rules only for selected source/destination pairs. -All other SYN packets will be rejected by the final -.Cm deny -rule. -.Pp -If you administer one or more subnets, you can take advantage of the -.Nm ipfw2 -syntax to specify address sets and or-blocks and write extremely -compact rulesets which selectively enable services to blocks -of clients, as below: -.Pp -.Dl "goodguys=\*q{ 10.1.2.0/24{20,35,66,18} or 10.2.3.0/28{6,3,11} }\*q" -.Dl "badguys=\*q10.1.2.0/24{8,38,60}\*q" -.Dl "" -.Dl "ipfw add allow ip from ${goodguys} to any" -.Dl "ipfw add deny ip from ${badguys} to any" -.Dl "... normal policies ..." -.Pp -The -.Nm ipfw1 -syntax would require a separate rule for each IP in the above -example. -.Pp -The -.Cm verrevpath -option could be used to do automated anti-spoofing by adding the -following to the top of a ruleset: -.Pp -.Dl "ipfw add deny ip from any to any not verrevpath in" -.Pp -This rule drops all incoming packets that appear to be coming to the -sytem on the wrong interface. For example, a packet with a source -address belonging to a host on a protected internal network would be -dropped if it tried to enter the system from an external interface. -.Ss DYNAMIC RULES -In order to protect a site from flood attacks involving fake -TCP packets, it is safer to use dynamic rules: -.Pp -.Dl "ipfw add check-state" -.Dl "ipfw add deny tcp from any to any established" -.Dl "ipfw add allow tcp from my-net to any setup keep-state" -.Pp -This will let the firewall install dynamic rules only for -those connection which start with a regular SYN packet coming -from the inside of our network. -Dynamic rules are checked when encountering the first -.Cm check-state -or -.Cm keep-state -rule. -A -.Cm check-state -rule should usually be placed near the beginning of the -ruleset to minimize the amount of work scanning the ruleset. -Your mileage may vary. -.Pp -To limit the number of connections a user can open -you can use the following type of rules: -.Pp -.Dl "ipfw add allow tcp from my-net/24 to any setup limit src-addr 10" -.Dl "ipfw add allow tcp from any to me setup limit src-addr 4" -.Pp -The former (assuming it runs on a gateway) will allow each host -on a /24 network to open at most 10 TCP connections. -The latter can be placed on a server to make sure that a single -client does not use more than 4 simultaneous connections. -.Pp -.Em BEWARE : -stateful rules can be subject to denial-of-service attacks -by a SYN-flood which opens a huge number of dynamic rules. -The effects of such attacks can be partially limited by -acting on a set of -.Xr sysctl 8 -variables which control the operation of the firewall. -.Pp -Here is a good usage of the -.Cm list -command to see accounting records and timestamp information: -.Pp -.Dl ipfw -at list -.Pp -or in short form without timestamps: -.Pp -.Dl ipfw -a list -.Pp -which is equivalent to: -.Pp -.Dl ipfw show -.Pp -Next rule diverts all incoming packets from 192.168.2.0/24 -to divert port 5000: -.Pp -.Dl ipfw divert 5000 ip from 192.168.2.0/24 to any in -.Pp -.Ss TRAFFIC SHAPING -The following rules show some of the applications of -.Nm -and -.Xr dummynet 4 -for simulations and the like. -.Pp -This rule drops random incoming packets with a probability -of 5%: -.Pp -.Dl "ipfw add prob 0.05 deny ip from any to any in" -.Pp -A similar effect can be achieved making use of dummynet pipes: -.Pp -.Dl "ipfw add pipe 10 ip from any to any" -.Dl "ipfw pipe 10 config plr 0.05" -.Pp -We can use pipes to artificially limit bandwidth, e.g. on a -machine acting as a router, if we want to limit traffic from -local clients on 192.168.2.0/24 we do: -.Pp -.Dl "ipfw add pipe 1 ip from 192.168.2.0/24 to any out" -.Dl "ipfw pipe 1 config bw 300Kbit/s queue 50KBytes" -.Pp -note that we use the -.Cm out -modifier so that the rule is not used twice. -Remember in fact that -.Nm -rules are checked both on incoming and outgoing packets. -.Pp -Should we want to simulate a bidirectional link with bandwidth -limitations, the correct way is the following: -.Pp -.Dl "ipfw add pipe 1 ip from any to any out" -.Dl "ipfw add pipe 2 ip from any to any in" -.Dl "ipfw pipe 1 config bw 64Kbit/s queue 10Kbytes" -.Dl "ipfw pipe 2 config bw 64Kbit/s queue 10Kbytes" -.Pp -The above can be very useful, e.g. if you want to see how -your fancy Web page will look for a residential user who -is connected only through a slow link. -You should not use only one pipe for both directions, unless -you want to simulate a half-duplex medium (e.g. AppleTalk, -Ethernet, IRDA). -It is not necessary that both pipes have the same configuration, -so we can also simulate asymmetric links. -.Pp -Should we want to verify network performance with the RED queue -management algorithm: -.Pp -.Dl "ipfw add pipe 1 ip from any to any" -.Dl "ipfw pipe 1 config bw 500Kbit/s queue 100 red 0.002/30/80/0.1" -.Pp -Another typical application of the traffic shaper is to -introduce some delay in the communication. -This can significantly affect applications which do a lot of Remote -Procedure Calls, and where the round-trip-time of the -connection often becomes a limiting factor much more than -bandwidth: -.Pp -.Dl "ipfw add pipe 1 ip from any to any out" -.Dl "ipfw add pipe 2 ip from any to any in" -.Dl "ipfw pipe 1 config delay 250ms bw 1Mbit/s" -.Dl "ipfw pipe 2 config delay 250ms bw 1Mbit/s" -.Pp -Per-flow queueing can be useful for a variety of purposes. -A very simple one is counting traffic: -.Pp -.Dl "ipfw add pipe 1 tcp from any to any" -.Dl "ipfw add pipe 1 udp from any to any" -.Dl "ipfw add pipe 1 ip from any to any" -.Dl "ipfw pipe 1 config mask all" -.Pp -The above set of rules will create queues (and collect -statistics) for all traffic. -Because the pipes have no limitations, the only effect is -collecting statistics. -Note that we need 3 rules, not just the last one, because -when -.Nm -tries to match IP packets it will not consider ports, so we -would not see connections on separate ports as different -ones. -.Pp -A more sophisticated example is limiting the outbound traffic -on a net with per-host limits, rather than per-network limits: -.Pp -.Dl "ipfw add pipe 1 ip from 192.168.2.0/24 to any out" -.Dl "ipfw add pipe 2 ip from any to 192.168.2.0/24 in" -.Dl "ipfw pipe 1 config mask src-ip 0x000000ff bw 200Kbit/s queue 20Kbytes" -.Dl "ipfw pipe 2 config mask dst-ip 0x000000ff bw 200Kbit/s queue 20Kbytes" -.Ss SETS OF RULES -To add a set of rules atomically, e.g. set 18: -.Pp -.Dl "ipfw set disable 18" -.Dl "ipfw add NN set 18 ... # repeat as needed" -.Dl "ipfw set enable 18" -.Pp -To delete a set of rules atomically the command is simply: -.Pp -.Dl "ipfw delete set 18" -.Pp -To test a ruleset and disable it and regain control if something goes wrong: -.Pp -.Dl "ipfw set disable 18" -.Dl "ipfw add NN set 18 ... # repeat as needed" -.Dl "ipfw set enable 18; echo done; sleep 30 && ipfw set disable 18" -.Pp -Here if everything goes well, you press control-C before the "sleep" -terminates, and your ruleset will be left active. Otherwise, e.g. if -you cannot access your box, the ruleset will be disabled after -the sleep terminates thus restoring the previous situation. -.Sh SEE ALSO -.Xr cpp 1 , -.Xr m4 1 , -.Xr divert 4 , -.Xr dummynet 4 , -.Xr ip 4 , -.Xr ipfirewall 4 , -.Xr protocols 5 , -.Xr services 5 , -.Xr reboot 8 , -.Xr sysctl 8 , -.Xr syslogd 8 -.Sh BUGS -The syntax has grown over the years and sometimes it might be confusing. -Unfortunately, backward compatibility prevents cleaning up mistakes -made in the definition of the syntax. -.Pp -.Em !!! WARNING !!! -.Pp -Misconfiguring the firewall can put your computer in an unusable state, -possibly shutting down network services and requiring console access to -regain control of it. -.Pp -Incoming packet fragments diverted by -.Cm divert -or -.Cm tee -are reassembled before delivery to the socket. -The action used on those packet is the one from the -rule which matches the first fragment of the packet. -.Pp -Packets that match a -.Cm tee -rule should not be immediately accepted, but should continue -going through the rule list. -This may be fixed in a later version. -.Pp -Packets diverted to userland, and then reinserted by a userland process -may lose various packet attributes. -The packet source interface name -will be preserved if it is shorter than 8 bytes and the userland process -saves and reuses the sockaddr_in -(as does -.Xr natd 8 ) ; -otherwise, it may be lost. -If a packet is reinserted in this manner, later rules may be incorrectly -applied, making the order of -.Cm divert -rules in the rule sequence very important. -.Sh AUTHORS -.An Ugen J.
