port forwarding

[Carl Parrish]

Info: Redhat 7.2 running ipchains

Okay I'm still looking for the best way to do some port forwarding. So
far my studies seems to say that I need to have ipmasqadm and mfw to do
what I want. Problem is they aren't *on* my system and when I do lsmod I
don't see either of them. Does anyone know of docs on how to install
them? I've been to the Linux Doc project and google/linux. Where I found
the ipmasqadm man page (good reading). but nothing on where to find it
or install it. I'm begining to think it would just be easier to install
iptables on my router.
