I'm using RedHat 5.2. I have 2 ethernet cards. One for internet (18.104.22.168) and the other one for my internal network (10.0.0.0). I want to allow workstations from my internal network to go to the internet with an IP address of the 22.214.171.124 network. i know that it's possible but i don't know how to do this. Any idea would be welcome. Thanks, Fred.
