"Now that the Internet has become a ubiquitous presence in our society, it seems only reasonable that every machine should have Internet access. And with a couple of Ethernet cards, some well-chosen software, and a little bit of brainpower, many people can manage to share a single Internet connection among more than one PC, whether that connection be a PPP dial-up connection, a DSL line, or a cable modem."

"In this case, the well-chosen software is ipchains. As described by its author, Paul Russell, ipchains "is an update to [and hopefully an improvement upon] the 2.0 Linux packet-filtering code, for the 2.2 Linux kernel." In a nutshell, it's a pretty neat way to make a firewall out of a 2.2 kernel Linux box, as well as providing access for multiple PCs using a single Internet connection. In this article, we will be talking about how to setup IP masquerading, allowing transparent proxying to the Internet."
