Pretty good for a home firewall :).

Look at my firewall script. Available from
http://home.pages.de/~lufthans/unix/. I've made a few changes that haven't
been added (things that RedHat needs because it's using bash instead of
bash2). If you want to use my script, let me know and I'll email you the
current tarball or you can probably just change the first line of the masq
script to call /usr/bin/bash2 instead of /usr/bin/bash.
The URL Doug sent seems very interesting and might better serve what you
need, but mine's probably better if you want to understand what it's doing
and be able to learn more.

Start off with a firewall that does masquerading (aka NAT). As you learn
more you can move to proxies or more advanced firewalling setups. If you
just want it to work without having to know the process, then a plain
firewall/masqerade setup is the way to go.
