fedora firewall/nat

I recently changed to Fedora CORE1 from Redhat 9 because of some vulnerabilities. Well, curiously I'm wondering if the firewall built into Fedora is worth enabling. Also, once it's enabled would it affect my NAT internet connection by not allowing traffic to reach computers located on the network behind ETH1?

Both use the same lokkit tool for configuration of iptables. I believe the firewalls rules they create are very simlar, if not identical, though I'm pretty sure that neither is capable of setting up NAT. They both have basically a generic interface that allows you to select certain ports to allow. I think guidedog (parallel app to guarddog) as well as a few others allow you to configure NAT. All of them still use the same iptables infrastructure to do NAT/packet-filtering, so you can use the same firewall script from RH9 on a Fedora box.
