I have a multihomed Red Hat 6.1 system. I am trying to have it function as a gateway to my win98 pc's. Linux is connected to my router, and it can get to the internet just fine with it's default gateway being my router. The problem I am having is that I cannot get any of my pc's to go through the linux box and out to the net. I am using ip forwarding and have real ip addresses for all pc's. (Not using NAT) I have my pc's gateway's set to the second card in the linux machine (eth1) My goal is to have one card be my internal card and the other external, and to put up a firewall so that my pc's can get to and go through Linux to the net, but nothing can get past the external card from the internet.
I have no idea what I am doing [wrong]. Do I need to set up any static routes to accomplish this? I have 32 static ip's and my netmask is .224.
If the router can be changed, then that is going to be the only solution other than NAT if you are going to run an internal firewall box. I think that such a change probably wouldn't affect anything up-stream
