无法从Ubuntu18.04Linux连接到PPTP VPN服务器
无法从Ubuntu18.04Linux连接到PPTP VPN服务器
提问于 2020-10-06 10:42:04
我尝试将PPTP作为VPN客户端。我尝试了很多方法来给一个给定的IP地址，用户名和密码使用。我试着同时使用GUI和终端，但没有成功。
在我尝试调试并发现一些错误之后。我试图解决这些问题，但没有成功。

我也有过同样的问题。我通过清除所有防火墙规则来修正它(请参阅https://serverfault.com/questions/200635/best-way-to-clear-all-iptables-rules如何使用iptables)。
我最近测试的防火墙似乎保留了一些规则，这开始阻碍VPN通信。
