I'm working on learning enough to get where you are. I've got the texts and
reading up and experimenting as I go. In my research I've found a few things that
might help. Check out:
http://cesdis.gsfc.nasa.gov/linux/misc/100mbps.html
Found this in the LINUX Ethernet - HOWTO. Might want to check out that one, the
basic networking one, but it's dated, the NET-3 and Firewalling and Proxy Server
ones as well if not already in your list of knowledge. Someone recommended the
Linux Network Toolkit to me also. I got an older version, 2 I think, that has
become a very helpful reference. It's based on someone like me trying for the
first time to set up a network using Linux as the core.
Hope this helps at least a little.
