I am running nefilter 1.2.7a on a Redhat 7.3 box kernel v. 2.4.18-24.7.x. I have experienced the following problems. Sometimes after making many changes and reloading the firewall after each change...the firewall will refuse to reload with the following output: [root@xxxxxxxxx root]# /etc/sysconfig/iptables condrestart iptables: Chain already exists iptables: Chain already exists iptables: Chain already exists iptables: Chain already exists iptables: Chain already exists Or if i get no error the firewall will not recognize any of the changes i have made. In either case i am forced to reboot the firewall to get things going again. Chip Upsal SysAdmin
