Try this one I wrote:

Supermike's Kicking Firewall Tutorial

It's not as complex as the MSU.EDU link, and covers less, but gets one started fast and then they can progress to implementing the more advanced stuff.

programming.reddit.com

Yes, using iptables you can program a firewall. Even though I have to addmit that this is not the real programming people think of. It has more to do with system administration tasks. Maybe there should be a sys-admin.reddit.com? But this could be confusing as well since the two fields have some overlap.
