Go to http://www.shorewall.net and download the Shorewall RPM. Also look at 
the Documentation and read the "Two-Interface Quick Guide" to get you 
started. You'll have a functioning, useful, easy-to-configure firewall 
within about 15 minutes or so. Shorewall is extremely powerful and flexible 
as a front-end to iptables, and since it's configured through simple text 
files you can change things remotely, via SSH, at a text terminal, or anywhere.

Shorewall also has an active mailing list and the author answers a good 
portion of the questions himself. A "five-star all-star kick-ass 
gotta-have-it" package and one of my all-time favorites.
