Firewall Setup

[Warren Togami]

Your ipchains kernel module is probably still loaded.  ipchains and iptables
cannot co-exist.

Try this
rmmod
modprobe ip_tables
Then run the rc.firewall-xxxxxx script.

Make sure you disable automatic start of the "ipchains" service.  Go into
"setup" and uncheck ipchains and firewall.  Check activate "iptables" even
though Red Hat's rules are empty, because that should automatically load the
ip_tables kernel module at boot-time before it runs your rc.firewall-xxxx
script at the bottom of your rc.local script.
