Looks like ya'll have gotten plenty of help already.
Try this...
Building a Home Network Routers and Firewalls for a primer.
Since "switches" and "routers" were discussed in the first 100 posts then I take it ya'll have already resolved that.
Give me a holler/ping later tonight if it still isn't working out. I just happen to have gotten off early today. (we had to evacuate the whole damn refinery today!)
