Connecting To License Server via CF Tunnel

I am trying to connect to a Windows machine running a CF Tunnel to another client Windows machine elsewhere in the world such that it can grab a license token. The client machines need an address that is formatted as follows: port#@. An example of the client input might be 25734@breakwater or [email protected], etc. The license server machine is tunneled to CF as I said. How can I configure CF to allow an entry on the client machine to resolve to the tunneled machine entering the port and machine name as formatted above.
