Links - Linux Firewalls

I have been making a lot of bookmarks lately, but not sharing. I should fix this. IPTables confuses me. I don't know why, it just does. The syntax doesn't seem as direct as pf.conf does on OpenBSD. I figure, this and Sendmail are my two biggest lacks of knowledge that needs correction for the moment. Among my firewall studies, I have come across these links:

- Linux.com's Firewall Primer: A good place to start
- Fire Wall Builder: This program will build firewalls for you. They also have a good cookbook to help you figure out what you need.
- Guarddog: "Protecting your computer with a cute little dog," is what they say, but it's a fairly decent GUI firewall builder for Linux, IMHO.
- My 4-Line Firewall: A smart tutorial on NAT/Masquerading/forwarding

I went into my /etc/sysconfig/iptables and looked around there for some help as well. I was able to do some crude cutting and pasting, but I don't exactly know how to build a system from scratch yet.
