对于 OpenVPN 用户来说，这个问题可能很常见，但我很沮丧，因为所有解决方案都失败了。我尝试了互联网上几乎所有能找到的解决方案来解决这个问题。我在 CentOS 7 NAT vps 服务器上设置了一个 OpenVPN。然后我在笔记本电脑（Windows 7）上安装了 OpenVPN GUI。起初一切正常：它连接上了，IP 地址也变了。但过了一会儿，它又被取消屏蔽，回到了真实 IP。我尝试了这些：
兼容性 - 右键单击 OpenVPN GUI，以兼容模式运行此程序 → 几乎全部尝试。IP 地址更改了近一分钟，再次自动更改为原始地址。
禁用 IPv6 - 转至控制面板 → 网络和 Internet → 网络连接 → 右键单击 Windows 适配器 v9 → 然后禁用 IPv6。不起作用。
重定向网关 def -
config.ovpn在服务器上编辑文件并在 Windows 7 上添加push "redirect-gateway def1"和编辑客户端文件并添加。 仍然没有任何效果。config.ovpnredirect-gateway def1
我一头雾水。这是来自客户端的日志文件：
