I was able to setup both the internal, and external connections on two separate network cards. Now I need help getting the ipchains to work (I have RH6.2). I looked at the instructions in the book where it says to open up netcfg& and choose ip4 forwarding and put ppp0 or slip0 for connection device and modified it for my eth0 (this is the nic hooked to the net), but I have left everything else blank, and it seems not to generate the two files it should (/etc/network being one of them). so I am looking for detailed step by step instructions please!!! and do not answer, just comment ( I do not want to lock the question till I test the solution)
Some more general info: my cable hookup is dhcp, and my internal NIC has the ip of 192.168.1.50 with netmask 255.255.255.0 (please use those numbers in solutions not any general ones).
