Red Hat installation Firewall / iptables

The Redhat installation has a firewall setting that was configured by someone else before I took it over. When asked to modify the firewall, I went to iptables and developed a script with some rules. It didn't work as I envisioned. So, I thought to ask if the Redhat firewall that was configured could be interfering with the iptables firewall, or do they feed into the same ruleset?

I would like clarification on this. I prefer iptables from the command line, as it seems more powerful and configurable.

RedHat's Firewall is done with iptables.
It just stores the iptables rules in /etc/sysconfig/iptables

You can make your own rules and save them as well with:

Code:

---

services iptables save

---

You just active your iptables service use /etc/rc.d/init.d/iptables start

or you can read this document.
