套接字客户端/服务器应用程序没有'；尽管开放了端口，但无法通过互联网工作

我已经用c#.NET套接字编程了一个TCP/IP服务器。使用本地网络可以很好地工作，但当我尝试在互联网上使用它时，客户端无法连接到服务器。

我确信我已经在路由器和windows防火墙（包括客户端和服务器）中打开了我的端口（14999），我还将我的计算机端口14999映射到路由器上的端口。

即使这样，我也会得到"一个现有的合作伙伴远程主机强制关闭了连接。"当我的客户端应用程序试图通过互联网连接到我的服务器时。

有一件事我注意到了。

当我使用Visual Studio调试服务器时，我使用http://www.yougetsignal.com/tools/open-ports/要检查14999端口，代码会碰到一个断点。

我已经被我们的这个卡住了，有人知道我能做什么吗？

非常感谢大家！

这是我的客户端应用程序代码：
