NAME
       ipfilter - IP packet filtering software

       IP Filter is software that provides packet filtering capabilities. On a properly setup system, it can be used to build a firewall.

       The IP Filter feature requires that the file /etc/ipf/pfil.ap be modified to include the names of the network interface(s) to be filtered.

       A system with filtering on the hme and qfe interfaces would have entries in /etc/ipf/pfil.ap such as those shown below.

       # IP Filter pfil autopush setup
       #
       # See autopush(1M) manpage for more information.
       #
       # Format of the entries in this file is:
       #
       #major  minor lastminor modules

       #le     -1      0       pfil
       #qe     -1      0       pfil
       hme     -1      0       pfil
       qfe     -1      0       pfil
