"I recently just got cable modem service in my area and decided
to subscribe. I was very pleased with the service and decided that
I wanted to share my Internet connection with my home network. So I
decided to setup my Linux server so I could share my connection. So
in the following article I'm going to describe how to share your
Internet connection with your network. So lets get started."
"To setup a Linux server share your internet connection you need
two network cards installed. One network card will connect to your
network and the other card will attach to you connection (such as
DSL/Cable modem). I have tested these instructions on Mandrake
Linux 7.2, but any of the latest distros should work."
