Unhappy Cant change firewall settings


My problem is that when I try to change the firewall setting from hight to medium or none it doesnt work...I change it and it ask me if I really want to change it and I answer yes...But when I look again its back on high..I use red hat 8.0...Does anyone knows what to do..?

I know this maybe is a kind of noob question...And I have tried to search this forum for similar questions but I didnt find any...So if this question is asked and answered Im sorry...
But I will be very grateful for any help.

If I remember correctly, this was flaw with the firewall gui program. When you say ok to new settings, it will actually save them and use the rules you put in place. But when you open the gui again you must put all your settings in again. You can test to see if your rules took place by going to the command line and typing /sbin/iptables -L (Ithink that's the command in RH) and seeing if the rulles look right. Then go and change something and do the command again to see if they took.

I'm not positive about that, but I kind of remember it being that way.;

Like benjithegreat98 mentioned, RedHat's Firewall software does not work properly.

You can try these Firewall GUIs instead:
http://firestarter.sourceforge.net/
http://www.ipcop.org/
http://www.fwbuilder.org/

But if you want to do it manually, take a look at the documentation on Netfilter/iptables.
http://www.netfilter.org/

To view your current firewall (iptables) rules, open a terminal window and type:
Code:
su -
iptables -vL
Note: the full path is /usr/sbin/iptables

A firewall can block incoming as well as outgoing packets.

As for aMSN, I never used it. So I can't help.
But have you checked the web site and the documents, maybe it is a problem with the software.
Or it could be that the MSN network is blocking you for some reason...
Also, do you have the most recent version ?
