Yes, this is certainly possible.  You need to be running at least
FreeBSD 4.6-STABLE from after August 16th 2002: any later version of
4.x-STABLE or -RELEASE will do fine, as will any 5.x version (although
running 5.x on a critical router is probably not the best idea).

Under 4.x you need to follow the instructions in the ipfw(8) man page
about enabling ipfw2 and compiling an appropriately customised kernel
-- see the sections "USING IPFW2 IN FreeBSD-STABLE" and "IPFW2
ENHANCEMENTS" towards the end of that page.  Under 5.x, the ipfw2 is
the default ipfw supplied with the system.

        Cheers,

        Matthew
