My only experience with VPN so far is as a user (e.g. log in to work)

Now I'm trying to set up Windows Server 2003 to connect to a VPN LAN (address space 192.168/16, no default gateway, protocol is PPTP). I want only the 192.168/16 network to go to the VPN connection, the rest should be routed through my server's default gateway.

So I thought I'd be able to do this with 'Routing and Remote Access'. There's a nice wizard where I selected "Secure connection between two private networks". I created a demand-dial device with my VPN credentials, and added a static route to the 192.168/16 network to trigger the DD interface.

I'm able to dial the connection in 'user mode' (with Control Panel/Network Connections/Create a new connection), and it works fine. In the RRAS the connection is 'unreachable' and I get a message box:

A connection to the remote computer could not be established. You might need to change the network settings for this connection.

In the event viewer I get an error with ID 20111

A Demand Dial connection to the remote interface VPN on port VPN3-4 was successfully initiated but failed to complete successfully because of the following error: A connection to the remote computer could not be established. You might need to change the network settings for this connection. For further assistance, click More Info or search Help and Support Center for this error number.

So, what is different between a user-mode VPN connection, and a VPN connection in RRAS? Are there special requirements for the VPN server (e.g. must it be another Win2k3 server) ?
