RMI differents machines

Question

Hey guys! I'm spanish man and my english is not very good.
Well, my problem is that server RMI is launched on port 1099 and the command line is like:
start java -classpath C:\xxx\xxx\xxx\xxx\xxxx.jar
-Djava.rmi.server.hostname=<NAME_MACHINE> -Djava.rmi.server.codebase=file:C:\xxx\xxx\xxx\xxx\ Server.Server -Xmx512
-Djava.security.policy=C:\xxx\xxx\xxx\xxx\java.policy engine.ComputeEngineand source:
Integer port  = 1099;
try {
            Server obj = new Server();
            MyFile stub = (MyFile) UnicastRemoteObject.exportObject(obj, 0);
            // Bind the remote object's stub in the registry
            Registry registry = LocateRegistry.createRegistry(port);
            registry.rebind("Traduction", stub);
            System.out.println("Server ready on port: " + port + "\n\n");
            Calendar cal = Calendar.getInstance();
            String fecha = " " + cal.getTime();
            System.out.println(fecha);
            for (int i = 0; i < fecha.length() + 1; i++) {
                System.out.print("-");
            System.out.println("\n");
        } catch (Exception e) {
            System.err.println("Server exception: " + e.toString());
            e.printStackTrace();
Client source:
if (System.getSecurityManager() == null) {
            System.setSecurityManager(new RMISecurityManager());
        System.setProperty("java.rmi.server.hostname", "<NAME_MACHINE>");
try {
            Registry registry = LocateRegistry.getRegistry(finalsVar.REMOTE_HOST);
            MyFile stub = (MyFile) registry.lookup("Traduction");
            response = stub.getFile(fichero);
        } catch (RemoteException re) {
            System.out.println("REMOTE_EXCEPTION");
            re.printStackTrace();
        } catch (NotBoundException nbe) {
            System.out.println("NOT_BOUND_EXCEPTION");
            nbe.printStackTrace();
        } catch (java.lang.ArithmeticException ae) {
            System.out.println("ARITHMETIC_EXCEPTION");
            ae.printStackTrace();
        }finalsVar.REMOTE_HOST is static IP of my server.
Then If I run the RMI applicattion on the same LAN and differents machines server/cleint, all works fine! But, when I run it out of the same LAN, Exception --> <<Connection Refused to 192.168.1.51>>, that IP is the local IP of my server in the LAN.
How I solve this problem?
Before nothing, Thanks!

Answer 1

If both data are the same, it causes an exception on the client. I can't remember it, because I'm not at work, I'm home.
How would run the server if you had the client on a different LAN where is the server?
In fact, these data should be the same?
I think the source is correct, no? But the parameter to start the server may be not correct.
I need help, I have several days trying to find the solution, but can't find it.
Once again, I'm sorry for my english.
