I've setup a firewall box with IPFW and NATD with what the handbook
had to offer on the subject, and now would like to get traffic
forwarded to behind my shmancy new firewall.
Google is purely confusing me on this one. From what I understand I
need to do one or more of the following:
setup a divert rule for ipfw
setup a fwd rule for ipfw
setup a redirect_port rule for natd
compile forwarding support into my kernel
Somehow I doubt it's all of the above. What am I supposed to do to
allow port forwarding?
Thanx for any pointers,
