671 disables certain TCP options as described by
677 might help remedy such problems with connections as randomly hanging
678 or other weird behavior.
679 Some network devices are known to be broken with respect to these options.
686 .Va net.inet.tcp.log_in_vain
688 .Va net.inet.udp.log_in_vain ,
693 are set to the given value.
701 will disable probing idle TCP connections to verify that the
702 peer is still up and reachable.
703 .It Va tcp_drop_synfin
710 will cause the kernel to ignore TCP frames that have both
711 the SYN and FIN flags set.
712 This prevents OS fingerprinting, but may break some legitimate applications.
713 This option is only available if the kernel was built with the
716 .It Va icmp_drop_redirect
723 will cause the kernel to ignore ICMP REDIRECT packets.
726 for more information.
727 .It Va icmp_log_redirect
734 will cause the kernel to log ICMP REDIRECT packets.
736 the log messages are not rate-limited, so this option should only be used
737 for troubleshooting networks.
740 for more information.
741 .It Va icmp_bmcastecho
745 to respond to broadcast or multicast ICMP ping packets.
748 for more information.
749 .It Va ip_portrange_first
753 this is the first port in the default portrange.
756 for more information.
757 .It Va ip_portrange_last
761 this is the last port in the default portrange.
764 for more information.
765 .It Va network_interfaces
767 Set to the list of network interfaces to configure on this host.
768 For example, if the only network devices in the system are the loopback device
772 driver, this could be set to
775 .Va ifconfig_ Ns Aq Ar interface
776 variable is also assumed to exist for each value of
778 It is also possible to add IP alias entries here in cases where
779 multiple IP addresses registered against a single interface are desired.
780 Assuming that the interface in question was
782 it might look something like this:
784 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
785 ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"
790 .Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
791 entry that is found, its contents are passed to
793 Execution stops at the first unsuccessful access, so if
794 something like this is present:
796 ifconfig_ed0_alias0="inet 127.0.0.251 netmask 0xffffffff"
797 ifconfig_ed0_alias1="inet 127.0.0.252 netmask 0xffffffff"
798 ifconfig_ed0_alias2="inet 127.0.0.253 netmask 0xffffffff"
799 ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
802 Then note that alias4 would
804 be added since the search would stop with the missing alias3 entry.
807 .Pa /etc/start_if. Ns Aq Ar interface
808 file is present, it is read and executed by the
810 interpreter before configuring the interface as specified in the
811 .Va ifconfig_ Ns Aq Ar interface
813 .Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
816 It is possible to bring up an interface with DHCP by setting the
817 .Va ifconfig_ Ns Aq Ar interface
820 For instance, to initialize the
822 device via DHCP, it is possible to use something like:
826 .It Va ipv6_network_interfaces
828 This is the IPv6 equivalent of
829 .Va network_interfaces .
830 Instead of setting the ifconfig variables as
831 .Va ifconfig_ Ns Aq Ar interface
832 they should be set as
833 .Va ipv6_ifconfig_ Ns Aq Ar interface .
834 Aliases should be set as
835 .Va ipv6_ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n .
836 .Va ipv6_prefix_ Ns Aq Ar interface
838 Interfaces that do not have a
839 .Va ipv6_ifconfig_ Ns Aq Ar interface
840 setting will be auto configured by
843 .Va ipv6_gateway_enable
846 Note that the IPv6 networking code does not support the
847 .Pa /etc/start_if. Ns Aq Ar interface
849 .It Va ipv6_default_interface
853 this is the default output interface for scoped addresses.
854 Now this works only for IPv6 link local multicast addresses.
855 .It Va cloned_interfaces
857 Set to the list of clonable network interfaces to create on this host.
859 .Va cloned_interfaces
860 are automatically appended to

863 .It Va gif_interfaces
867 tunnel interfaces to configure on this host.
869 .Va gifconfig_ Ns Aq Ar interface
870 variable is assumed to exist for each value of
872 The value of this variable is used to configure the link layer of the
873 tunnel according to the syntax of the
877 Additionally, this option ensures that each listed interface is created via the
881 before attempting to configure it.
882 .It Va sppp_interfaces
886 interfaces to configure on this host.
888 .Va spppconfig_ Ns Aq Ar interface
889 variable is assumed to exist for each value of
