First off I will start by saying that networking is the one computer topic I never really learned about, not sure why just never did.

Here is my situation, I basicly have a single thick cable that provides my house with phone, cable, digital conectionfor my alarm system, and most importantly my 100 mb/s internet connection. when the cable enters my house in the basement it is split and cable tv is sent to the cable jacks, phone to phone jacks, etc. The 'net connection is fed into what is an off the shelf netgear switch (FS 108) which then connects to all the network jacks in my house. This is a nice system because In theory all of my computers are networked together without having to do any of my own wiring (read wire hanging out windows or running across the hall). The problem is that the network traffic looks like internet traffic to zone alarm thus the computers can't be networked with zone alarm on. My question is what would be the best / easiest / cheapest way to allow the computers to be networked without having to rely on the windows built in firewall (shudder).
