You only need two ethernet cards if you're going to use that machine to 
share the internet. If you're want a firewall, to give added saftety, 
then one ethernet card, or none if you're using dialup, is perfectly ok. 
And just so you know there are several GUI programs around to help you 
setup iptables to suit our exact needs. However, Fedora comes with a 
simple version of such a setup tool that may very well be enough to suit 
your needs.

do teh following command to get your kernel info:
# uname -sr

Iptables or similiar, should work on a pre 2.4 kernel. However I doubt 
you have such an old kernel.
