How to install a simple network gateway
This HOWTO is aimed at first time Linux users who want to set up a Linux box as a gateway to the Internet. This is a very simple HOWTO and it does not go deeply into many issues. Use it if you find the other HOWTO's available too much for you to understand. It covers setting up DHCP, DNS, and iptables. When you've finished, all your clients need to do is to plug in a local network cable and switch the computer on.
I used Red Hat Linux 9 as the distribution for this exercise, but the instructions should work equally well for most Red Hat-derived distros, and, with little or no modification, for other distros as well.
