遗憾的是，我居住的国家对许多网站进行了过滤和屏蔽，因此我使用 VPN。
最近，我在 Ubuntu 18.04 中使用 VPN 时遇到了大学 WiFi 连接问题；虽然 VPN 应用程序（我从 VPN 提供商处获得）连接到他们的服务器，但被阻止的网站（例如 YouTube）仍然被阻止！
我的 Windows 系统上的相同 VPN 运行正常！
我认为这可能是来自我的浏览器，所以我 ping 了一些被阻止的网站，但它们不起作用。
我该如何解决这个问题？
更新
我刚刚发现我的 vpn 连接时不会改变我的 ip 地址！我用多个 ip 查找器网站测试了这一点。这里是ifconfig连接前后我的命令的内容：

答案1
对您想要访问的站点地址进行跟踪路由，查看您通过哪条路径进行连接：
traceroute -n 8.8.8.8
您可能需要通过 VPN 适配器添加默认路由，请参阅：如何通过 vpn 适配器路由所有流量？
