C# NetMQ：我不熟悉.Net和NetMQ。我正在.Net中开发一个Pub:Sub模式应用程序

这是我的publisher代码

 private void CreateMessages()
    {
        using (var QuotePublishSocket = new PublisherSocket("tcp://192.168.0.9:9011"))
        {
            QuotePublishSocket.Options.SendHighWatermark = 10009;
            QuotePublishSocket.Bind("tcp://*:9011");
            QuotePublishSocket.SendFrame("Hello :" + DateTimeOffset.Now.ToUnixTimeMilliseconds());;

        }
    }

这是我的订户代码

private void CreateSubscriberTread(string portNo) {
        using (var subSocket = new SubscriberSocket())
        {
            subSocket.Options.ReceiveHighWatermark = 1000;
            subSocket.Connect("tcp://192.168.0.9:9011");
            //subSocket.Bind("tcp://*:9011");
            subSocket.Subscribe("");
            Console.WriteLine("Subscriber socket connecting...");
            while (true)
            {
                string messageReceived = subSocket.ReceiveFrameString();
                Console.WriteLine(messageReceived );

            }
        }

    }

但是，当我在同一台PC上运行publisher和subscriber时，它会工作，我会从publisher接收数据。但当我在两台不同的pc上运行publisher和subscriber时，我不会收到任何数据。请告诉我我做错了什么。
