Then you'll need some kind of proxy server. Services are provide via an address AND a port. You need to listen there and then forward to the real service

// to bind a specif ip address

            InetAddress addrIpName = InetAddress.getByName("172.30.1.18");
//      or
//      InetAddress addrName = InetAddress.getByName("myhost.name");
//    or
//            InetAddress addrIp = InetAddress.getByAddress(new byte[] { (byte)172,30,1,18});
            int port = 4446;
                int bl = 5;
            ServerSocket serverSocket = new ServerSocket(port,bl,addrIpName);
