I might clarify something or also ask these additional questions. Lets assume all my syntax is correct. Then maybe it's a package i haven't installed or.. another theory is maybe you can't NAT with only 1 nic ?? That wouldn't make since, but it's the only other things I can thing of.
I have the iptables and ipmasq packages installed. The ipmasq will override my iptables rules at bootup (easily fixed) and I've gone to manually flush them. I'm also not quite sure what the ipmasq package has that's needed to masquerade other than iptables, thinking that iptables had masq modules??
Again, I have no problems forwarding masqueraded packets to my internal boxes from the Internet point, but NAT will not work
