For lack of time, I am abandoning the remaining information that you
provided, sorry.

Here is my suggestion...

If you have GUI on that F9 box, install one of the many GUI firewall
editing tools like firestarter, and use it to enable port forwarding,
and likely network translation -- this assumes that the F9 box uses a
different interface and IP to get to the internet than the one it uses
to connect to the rest of the LAN, generally speaking you need two
network cards for that.

If you do not have GUI on that box, you'll have to read up on IPTABLES
so you can set up the above manually.

Have each of the other machines use than F9 box as their network gateway.

This is a typical, relatively easy setup which should allow all the
machines to have basic access to the internet and to each other.

If this F9 machines happens to be a server, you may want to consider
using Centos 5.2 on it instead.
