Firewall Problems
This is a very NEWBIE problem I'm sure.....
I installed Linux for the first time last night (RedHat v8) and I seem to be having some problems connecting to the internet. I've configured my NIC correctly with the settings from my ISP so I suspected my problem might be with my firewall settings. WIth this in mind I went to System Settings>Security Level to try to change them last night. When the window comes up it shows the level as High which I assume is blocking all traffic. I've set this to Medium and No Firewall and neither seems to help. I've even tired to use Customize to select the service I want to use but again no luck. Also if I exit and go back into System Settings>Security Level it shows the security level as High again. It looks like my changes didn't take. It's a pretty simple interface so I can't imagine that I'm doing something wrong. Any ideas on what might be happening?
Let me know if I'm leaving out any vital info that might be helpful.
Thanks

First is you card working right in Linux?
Do you get anything about a eth0?
What GUI are you using (KDE Gnome) as well. so we can point you to where to look for things.

Yes, it appears to be working correctly. When I boot it initilizes and if I check System Settings>Network eth0 shows as active. I can also ping the eth0 IP address. Is there something else that I should check?
I have tried using both KDE and Gnome as I've been looking into this problem but right now I'm using Gnome.

Open a terminal window ( System Tools -> Terminal )
and type: service iptables stop
This turns OFF the firewall, can you now connect to the internet ?
