     You need to use the method which a router to router connection uses.
This involves setting up a demand-dial interface on the server.

    Configure a demand dial interface, and add a static route (using the new
static route wizard in RRAS). You select the demand dial interface from the
dropdown list as the interface to link with the route. Set up an account
with dialup privileges with the same name as the demand dial interface.
Check that the option "allow a router to connect" (or whatever it says in
German!) is checked.

    When you connect from the Cisco, use the name of the demand dial
interface as the username. The Cisco will then connect to the dd interface
instead of the default internal interface. The route back to the Cisco's
subnet will be added to the routing table through the link. (The default
option only sets up a host route back to the calling machine, since it is
designed for a simple client-server connection, not another router).

    The advantage of this method is that you don't need to know what IP
address the connection uses. You just use the name of the demand dial
connection, and the system looks after it. And the route is automatically
added and removed when the remote router connects or disconnects. When not
in use, the static route is stored in the registry.
