I am totally new to Linux so please bear with me. I just installed Red Hat on a clean system (reformatted, installed) I then ran the update agent and received and installed all the updates including the newest kernel.
During setup the installation asked me for my preference of firewall security level, (high, medium, off) I selected medium and allowed HTTP. However, the settings did not hold when I checked them using the graphical interface for security level selection, they are always on High no customization. I attempted to change them using this interface and again nothing. Next, I tried using lokkit and this also did not permanently change the settings. I researched a bit and found a suggestion to edit them using the command /usr/sbin/setup, this too had no permanent change to the system.
I am always logged in as root while working on this issue.
This is a Redhat bug. No matter what you set your firewall level at, it will always display it as "high" when you run the graphical interface. But don't dispair, your firewall is still set to medium or whatever you set it as. It just displays "high" by default.
Is there another way to edit firewall settings so that you can circumvent this bug? I tried running gnome-lokkit, but I'm not sure if I'm doing it right.
You can run iptables -L as root to get a list of all your iptables rules. You can also run firestarter. I personally like doing the iptables rules by hand, but I've seen people running it and it looks pretty useful.
Otherwise just set the firewall to whatever level you want in the GUI and disregard the fact that it says "high" as default.
