Gang, Ok I would like to run a small network on my PC using Virtual PCs to test ISA 2004 server. What I want to do is open a Virtual PC with 2 NICs, and run ISA server 2004 on it. Then run a second Virtual PC that "thinks" it is on the network of one of the NICs from the first VPC with ISA server on it. I know that some of you do this, however I can't seem to wrap my head around how to do it. 1) I have to Virtual NICs on the ISA Server box, one has the Static setting from the LAN the real PC runs on, what do I give the other NIC for IP Ranges for the "inside" network? 2) How do I tell the 2cd VPC to use the ISA Server box as the Gateway? 3) Do I really need two NICs on the ISA Server Virtual PC? -Wayne
