I am confused over the use of IPTables and Firewall. I have IPTables set with masquerade for internet sharing. Since IPtables is in place shall I disable Firewall that can be viewed from System->Administration menu? Where I have to implement Firwall rules in IPTables? I am using Redhat 5.
Hi vijaysoft, afaik when they say firewall its the GUI counterpart of iptables, if you are proficient enough in IPTables you can setup firewall rules in it. As per experience in SLES, if I disable GUI Firewall it also flushes all the rules of my iptables.
Thanks for your input. You are right. When I added a new Trusted item to my GUI Firewall, I lost all the iptable configuration which has masquerade settings in it. I am wondering is there any way to recover the old configuration.
Sorry, misread which disto you were using. You might want to check if there is a background process which periodically backs up items in /etc/sysconfig/ and other files in /etc/. It may back up the config files your system uses for the firewall interface.
