Actually, for newer kernel 2.4+ Fedora-based distros
(including CentOS 3+), it's recommended you use the "service
iptables save" (or "/etc/init.d/iptables save").
It basically parses the currently configured tables in the
kernel and outputs them (in short-hand form) to the
configuration file /etc/sysconfig/iptables.
Then configure the iptables script to start at boot for
run-levels 2+. FYI, I'm not sure what happens to any "saved
changes" if you re-configure /etc/sysconfig/iptables from the
"Firewall Setup" though. So do that with care.
