L2TP VPN with single NIC on server

Hi,

I have a W2K3 server running behind a firewall like this:

VPN client <-> NAT FW <-> Internet <-> NAT FW <-> W2K3 RRAS Server

I know this is not a recommended solution, but want to use it anyway. The
client is configured according to KB 818043. On the firewall on the server
side UDP ports 500 and 4500 is forwarded to the RRAS server.

The problem is: I can connect to the RRAS Server, I can reach all other
resources on the internal network from the VPN client, but I can not
communicate with the RRAS server itself and reach the network shares there.
The server is single NIC with one IP except of course the extra IP for the
RAS connection.

Any ideas?

Posting the results of ipconfig /all on both client and server may help.
