Looking for W2K3 to route back to imcoming gateway

    We have a W2K3 server (say which is on a local LAN.

    There are two internet connections, both running Cisco routers, (the main one) and (the backup/incoming mail

    When we use the .254 cisco to forward ports from outside (ie 25 or 3389) to
    the server, everything works OK. If we do the same with the backup connection
    (.253) the connection from outside to either 25 or 3389 does not work.

    I think this is because the W2K3 server is handed to originating public IP
    address when a connection is made to either 25 or 3389 and by default goes
    back out by .254.

    Is there any way to make the W2K3 Server send the packets back through the
    gateway that the connection came through, rather than always going out by the
    default connection?

    Thanks for your help - and I hope I've explained it OK!

    Kind regards,

    Hi Bob,

    Thanks for the info. The page you suggested is exactly what I am looking
    for - but it seems to be missing the information on how to use either RIP,
    BGP or OSPF. Like that post the major concern if for connections from the
    internet being able to connect through both the gateways at the same time to
    the server.

    Thanks Bob.

    Kind regards,

    Just one short point.

    If you are using that 3389 for RemoteDesktop / Terminal service connections
    I would change it to diffrent port because of the nature of the service.

    You can do this by changing the PortNumber Key in the registry.

    And then appending that port to the clients connection information

    In IP:port# format.

    Of course if it is not meant to be public facing then ignore this!
