Packet Filter (PF)

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 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. Look at fwd.

Please note that typical mistake is that people often forget about the following:

Code:

To enable [FILE]fwd[/FILE] a custom kernel needs to be compiled with the option options [FILE]IPFIREWALL_FORWARD[/FILE].
