Packet Filter (PF) (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls-pf.html)

http://www.freebsd.org/cgi/man.cgi?query=pf.conf&sektion=5&apropos=0&manpath=FreeBSD+8.1-RELEASE

Some time ago the OpenBSD PF FAQ (http://www.openbsd.org/faq/pf/index.html) helped me to learn PF. Unfortunately, the difference in syntax between PF on FreeBSD 8.x and PF on OpenBSD 4.8 has become bigger and this FAQ will not help you a lot now :-( AFAIK, FreeBSD 8.x uses quite old version of PF - from OpenBSD 4.1.

Another solution might be IPFW (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls-ipfw.html). Look at fwd.

Please note that typical mistake is that people often forget about the following:
To enable fwd a custom kernel needs to be compiled with the option options IPFIREWALL_FORWARD.
