For the most part system-config-firewall on CentOS 5.5 has been what I rely on and is simple enough for my needs. I'm a home PC Linux user. Sometimes I'll look at /sbin/iptables --list and try to understand how the chain of rules process the connections. Since I don't configure firewalls on a regular in that manner; it makes me cringe to think of how much time it would take for me to configure something on the fly. It probably wouldn't take me long but I like to get things done like yesterday. I've never configured shorewall; but your article on APF really makes firewall configuration appear more straight forward if not kinda fun to do! I think I'll give it a go.Thank you, Vincent.
