    Default Problems With Client/Server Operations

    Would it be possible to program an application to be able to setup a client/server connection between to instances of the same app without port forwarding?

    So, somehow initiate a request from the port so the router will accept the incoming socket request from the client end of the app?

    And, to conserve thread space, I am unable to connect to my client/server app externally WITH port forwarding and all firewalls turned off (using external IP).

    It's a basic server.accept() block method and new socket(ip,port) setup (I wont waste time showing the actual code). Are there any other factors I should check?

    Note: The server is instantiated with the constructor:
    server = new ServerSocket(port);
    client = server.accept();

    Not familiar with port forwarding.
    Google gave me:
    Port Forwarding simply tells the router which computer on the local area network to send the data to.

    What are you trying to do? Where are the two programs that you want to connect to each other?
    This sounds like where local host(127.0.0.1) is used for testing client/server apps on one pc.

    Have the application open on two machines running on separate networks and be able to connect to each other through client/host sockets.

    Port Forwarding sends incoming information through a network port to that particular machine. Without it, the router will block incoming requests by default.
