Connection refused

Jeg kører en server lokalt og det har virket fint... lige indtil jeg fik Internet. Koden ser således ud:

    String regNavn = "Server";
    try
    {
      LocateRegistry.createRegistry(1099);
      Server server = new Server();
      Naming.rebind(regNavn,server);
      System.out.println(regNavn + " - OP-Serveren er startet!");
    }
    catch(Exception e)
    {
      System.err.println("Fejl i server-opstart: " + e);
      e.printStackTrace();
    }

og fejlen lyder som følgende:

Fejl i server-opstart: java.rmi.ConnectException: Connection refused to host: 10.0.0.8; nested exception is:
    java.net.ConnectException: Connection refused: connect

Er der nogen der kan se hvad problemet er?
Jeg kører ikke nogen firewall, og har ikke ændret noget i security manager
