A feature of IPchains is IP masquerading. It consists most of the time
(but not restricted to) of making all the machines behind your firewall
look like your firewall machine from the outside.

So if you have only one IP, you can still have a home network with many
machines accessing the internet. IP masq will translate the internal IPs
to the external one, and also make sure that the reverse packets come back
to the right machine.

IPchains has a lot more features.
$ man ipchains
for more info.

I also recommend the book "Building OpenBSD and Linux Firewalls" printed
by Wiley. A good place to start.
