Connecting PCs and accessing network

How many PCs are you looking at for your whole network. How is your existing network set up now? I don't understand (if I'm reading this right) why you would want to connect two PC via crossover (null) and then connect to network?

Post a little more info about your setup, please.

If you want to both connect the two directly, and have access to the regular LAN, each PC will require two network cards. for the two lan cards with the crossover cable between them make sure you assign IP addresses for them that are a different netwrok than the existing network. when you wish to use this "private" LAN you will have to use the IP address of the other computer's private LAN or you will not be able to guarantee which route the packets take.
Frankly, unless you require incredible bandwidth, you are better off just connecting the two computers to the exisitng lan with a switch. that way, traffic between the two is routed through the switch and never reaches the "public" part of the LAN.
