FreeBSD as router. Please help!

I'm trying to setup my server as a router because of the licensing issue.
The wan to server portion is working just fine but I can't figure out how to get the connection between the server.
specific instructions would really be good. All tutorials I've found so far on google haven't worked.

Thanks for the help

Start with the FreeBSD handbook it tell you all about how to setup this stuff:
