RRAS

I have a lab network that has no connection to the Internet. I need to create one on a temporary basis through our corporate network so that the lab clients can access the Internet.

I installed a second NIC in a Win2k server, installed RRAS and set up routing. The server is not logging in to either the lab or the corporate network.

I am able to connect to the Internet from the server but not from the lab clients. I am able to ping the IP address of the
“corporate” NIC from the lab clients but not it’s default gateway.

What am I missing? Am I approaching this the right way?
