It looks like I can't do this from the Applications --> System
Settings --> Security Level GUI. I can allow ports 80 and 3306, but
it doesn't look like I can limit the port 3306 connections to just 2
specific hosts. I would have to craft an IPTABLES script. Am I right
here, and if so, what would be the right way to add specific IPTABLES
rules without interfering with the Security Level applet?

I (as the other posters) will recommend you to learn iptables, and if
you want a very easy way to configure your firewall and build *quite*
complex per-interface rule sets, I'd strongly recommend you take a
look at fwbuilder (there are the packages for it in the pre-extras
repo [http://fedoraproject.org/pre-extras])
Thank you. How do I implement iptables rules without interfering with
what the Security Level applet sets?
