Thanks for your input everyone. Yes Jim you are right - what you have drawn below is REALLY how I should be using the 2 subnets. I was trying to get away with NOT using a router and thought that putting a static route in RRAS would route the packets (received from the ISP\GW on subnet1 but destined for subnet2) backout ISA's external NIC (to the hub) where it could then be received by the 2nd PC on subnet2. As someone else pointed out to me the only way to use the 2nd subnet without a router is to attach the 2nd PC (in subnet 2) to a hub connected to ISA's INTERNAL NIC NOT the EXTERNAL NIC as I have been trying to do. Haven't had time to try this yet but this should work I'm told. Thanks for your help - much appreciated.

Those two subnets are intended to be used this way: ISP | - IP1 |- Subnet 1 | -IP2 Router | - IP1 |- Subnet 2 | - IP2-6 ISA | - RFC-1918 Subnet
