修改 我弄清楚问题是什么，但现在我遇到了另一个问题。我想从另一台PC远程控制1台PC，该部分可以工作，但你必须将端口转发。可以像TeamViewer一样连接吗？所以我绕过了防火墙并且不必向前移动？如果有，怎么样？如果有人可以帮助我，那将是非常棒的：）
原始帖子
我制作了一个代码，以便您可以从另一台计算机控制计算机。唯一的问题是，它不适用于您自己网络之外的计算机（也许我连接了错误的IP？我尝试了该人的IPv4和来自WhatIsMyIP的IP）。如何在网络外部进行此项工作？
这是服务器类（我删除了很多代码，因为它没有意义）

Team Viewer的工作方式是交互中有第三台计算机。团队查看器在互联网上有一个公共服务器，您和您要连接的人都可以与之通信，而它所做的只是充当将来自一端的传入消息转发到另一端的桥接器。现在两端都有出站连接，不需要端口转发。
要对您的系统执行相同操作，您需要在互联网上设置，托管（付费）和维护公共服务器，以便程序的所有用户都能与之通信并充当通信桥梁。
步骤如下：
