Any recommendation for Redhat Linux additional firewall?

[wacky_sung]

I am wonder is there any additional Redhat Linux firewall which i can install beside those default buildin firewall.People telling to use netfilter or iptables but that's very difficult to install it inspite reading all those instruction.Is there any other alternatives?

I figured a program would come with red hat-- shorewall came with mine, and if you read through the help files and its website, it becomes pretty easy to configure, even for a newb like me. Also, gshield has been recomended to me. As far as being installed, iptables should already be.
If you're still not satisfied, google.
