Hi Scott,

  I, like Dan, just edit my firewall script in /etc/sysconfig/ipchains.
However, I also recommend Robert Ziegler's _Linux Firewalls_ book.
Below is a link to Ziegler's website in which he advertises his book.
He also has a Firewall Design Tool link that I've heard some good
things about.
