Thanks Tom,
	I'll check out Cisco's docs.  At the moment I'm using a Linksys AG300.
It will do the basics of what I want with firewall and NAT, but I would
like to learn how to make Fedora do it as our SOHO network grows.  I've
primarily used Fedora for getting work done over the years, now I want
to get under the bonnet and start tinkering.  This Linux Networking
Cookbook that arrived yesterday is very useful, but I just need a few
gaps filling in along the way.  There's another linux network security
book coming in a couple of weeks, so I can build on things some more.

Thanks again.
