NAME
ipfw -- IP packet filter and traffic accounting
DESCRIPTION
The ipfw system facility allows filtering, redirecting, and other opera-
tions on IP packets travelling through network interfaces.
The user interface for ipfw is implemented by the ipfw(8) utility, so
please refer to the ipfw(8) manpage for a complete description of the
ipfw capabilities and how to use it.
Kernel Options
The following options in the kernel configuration file are related to
ipfw operation:
IPFIREWALL enable ipfw
IPFIREWALL_VERBOSE enable ipfw logging
IPFIREWALL_VERBOSE_LIMIT limit ipfw logging
IPDIVERT enable divert(4) sockets
