windows as a router

hi all,

I am using windows 2000 server on a generic PC.

For testing purposes I need to have this PC act as a router.
i have installed 2 NIC’s
i have verified connectivity fromt he Windows 200 serer PC

I have installed RRAS and configured it as a router

the problem is that client PC’s that use the windows 2000 sevrer as a gateway cannot access the network on other side of router UNTIL the windows 2000 server box does.

so i am guessing there is a demand dial setting or similar aomewhere but i have exhausted my patience trying to find it.

Please help!
