How did you set it up? I'm looking to do the same thing. I think, though, that you would have all traffic coming through the Public IP and have the private interface disabled. The public IP would be on the same subnet as your internal network and is (obviously) behind the firewall. Then, any traffic that is routed to the concentrator's public interface does an immediate turnaround and is routed to the internal network. That's what you're trying to accomplish, right? Here's a post I found that mentions what you're trying to do.
