我有一个用以下方式制作的 .ovpn这里
我测试了端口是否正在使用 netstat 连接：
$ nc -v -u -z -w 3 <ip> 443
Connection to <ip> 443 port [udp/https] succeeded!
它看起来如下所示。我下载了它并尝试让它与 Gnome 3.18 一起工作。到目前为止，运气不佳。
在客户端上：
sudo apt-get install network-manager-openvpn-gnome
然后设置->网络->+（左下）->VPN->从文件导入...
它出现在列表中，但如果我启用它，浏览器就无法工作。
我遗漏了什么？提前致谢！

答案1
问题是我尝试在端口 443 上使用 UDP，但没有成功。切换到端口 53 (DNS) 后，一切正常。
