Fedora Core 3 Firewall
 

I am using Fedora Core 3 with Gnome.
When I click APPLICATIONS / SYSTEM SETTINGS / SECURITY LEVEL
I am able to change the configuration of my firewall.

Where is that firewall configuration actually located? I thought it had to
do with iptables. (?)

However, after I made a change in the GUI, I could not see the specific
port listed when I ran 'iptables -L'

just curious,

A copy of the firewall is saved in /etc/sysconfig/iptables. Any changes you make should appear in the output of 'iptables -L' though. Maybe you didn't click the 'Ok' button? It might also help if you posted the output of iptables -L and told us the port you wanted to open.

Thanks for your input. I saw the configuration using /etc/sysconfig/iptables -L
I read up on iptables and understand the firewall better now
