This week's techmail was Firewall configuration with system-config-firewall which discusses the niceties of using Fedora's system-config-firewall to configure iptables. I'm not much of a GUI guy, but the interface for the firewall configuration is really slick. Will it replace my use of editing iptables rules in /etc/sysconfig/iptables? Probably not. But if you were afraid of editing a text file to setup your firewall rules, then using system-config-firewall will be welcome for you.
