I currently use a firewall setup using the Fedora Firewall Configuration program. I would like to remove this firewall so that I can use my own Firewall script that uses iptables.
How can I do this?

I am using Ubuntu Server 12.04. I am working on a Transparent Firewall configuration. I need to configure an ACTIVE/ACTIVE firewall configuration, using iptables.
The two firewalls will get traffic, and the job of dividing the traffic is done by Openflow switches.
I noticed this morning the iptables firewall was not starting due to the fact that I rebuilt the kernel and forgot to include the relevent Netfilter modules. So I added those and rebooted. The firewall still fails, but rather that referring to the non-available ip_tables module, it now just says iptables.init: iptables: Applying firewall rules: iptables-restore: line 13 failed.
I have a network that at the moment is isolated from the internet. We are going to connect it to an existing adsl line that has a firewall,but we want to add another firewall behind it as we do not have total control over the existing firewall. The only thing we want to allow is smtp access for one computer.
When Sperical Cow hits the digital shelves sometime in late October or early November, users will have to get used to a new firewall management application. Sperical Cow is, of course the code-name for Fedora 18, the next stable release of Fedora.
