Make sure you have bind installed and two ethernet cards installed. Give the lan ethernet card a static IP such as 192.168.0.1 Use the firestarter package (www.fs-security.com). http://www.fs-security.com/ Run the wizard (5 screens) http://www.fs-security.com/pics/wizard3.png You're done! If you are curious about how to do this yourself, check /etc/ firestarter there is a "firewall" config file that shows every step the program did to enable forwarding, etc. If you are generally happy with the program, you can add in custom scripts in the user-pre file- they load before firestarters other rules and take precendence. If you hate the program, study what options it passes under the config file.
