[USR-TC] routeing out of the box

Warning first time to run a TC I have a TC with a dual PRI card, netserver pri, and Net Man card. I have it set up to the point that a user can dial in and get authenticated. Once they are connected they can not get anywhere. What I mean is they can not ping anything even our router (there gateway). From the console of the netserver card I can ping everything in the world. I currently do not have the Net Management card plugged into the switch; just the Net server card is plugged in. First do I need both cards plugged into our switch? Is there any other reason for user not being able to get out of the TC box? Thanks, Rick
