Networking question

[Thomas E. Dukes]

Hello,

For someone that has been using redhat/linux since 1996, this is probably a
really dumb question.

BUT......

I have had a single PC with a dual boot setup and now I have (for sometime)
separate systems.  Yippeeee!!

OK here's the question:

I a couple pentium II machine I can get my hands on.  Because my one FC 2 PC
is handling everything, I'd like to setup these older machines to do mail,
mysql and maybe some other services to take the load off the main PC.

If I add these PCs to the network behind my firewall, how do I direct these
services to the various PCs?  Is this a firewall thing or DNS?

Can someone point me to a good (current) howto on this subject?  Is this
load balancing?

TIA
