Don't do it man!! I tried every frontend there is to configure iptables. They each hosed my system in different ways. Iptables is a little tricky at first, but trust me, do it yourself. I just finished writting my iptables script by hand and I learned way more and have a better firewall for it. We will help you along the way. Check out Netfilter.org and look at some good sample scripts. Then post here and we'll help you tame the wild netfilter..
