When I tried to do the same to give my WinXP box access to the internet I couldn't get it right. When I connect to internet using eth0 everything is fine.

Download the software and it will show you how to set up the configuration files (simple text files) to get the result you want. Shorewall will configure everything: gateway service, routing, masquerading, firewall rules, and allowing some ports access from the Internet to your firewall or to an internal machine if you so desire. > > I am also working on a more complete document for what you want, called the "Small Netserver HOWTO". It will show you how to set up DHCP, DNS, and NTP for your home network on that Fedora box, which will make your life much easier from then on. It is unfortunately not complete yet, but hopefully what I have so far will help give you a little guidance and I'll finish it soon.

I will have a look at the webpages you recommended, they look useful. Thanks to everyone for the many answers. .David
