服务器无法从我的本地互联网外部访问

Question

嘿，我正在尝试创建一个连接到服务器并从中获取一些信息的应用程序。 该应用程序运行良好......仅来自我自己的网络。 如何使其在不属于我自己的localhost的网络上工作。

代码到服务器：

            if(socketForClient.Connected)
            {
                connections++;
                Console.WriteLine("Client Connected: " + socketForClient.RemoteEndPoint);
                NetworkStream networkStream = new NetworkStream(socketForClient);
