Andres, Windows to Windows connections via ssh will not function in the same manner as a Windows to Unix connection. Windows Mathematica programs use the SharedMemory LinkProtocol which is incompatible with data forwarding over ssh. If you want to use ssh connections between Windows machines, you will need to tunnel the TCPIP LinkProtocol over ssh. Sincerely, Steve Wilson Wolfram Research Inc.
