PPTP 疑似被运营商掐了？

  •   
  •   KokongW · 2014-05-15 20:06:25 +08:00 · 11064 次点击
    这是一个创建于 3848 天前的主题，其中的信息可能已经有所发展或是发生改变。
    今天突然用PPTP连接不上VPN了，开启debug看到log里有一行“LCP terminated by peer (Failed to authenticate ourselves to peer)”

    BTW，如果这不是ISP封PPTP，那如果ISP封了PPTP，会在Log里显示什么？

    Thank you.

    从你给出的错误来看，是你自己这边请求断开的，没有证据表明是ISP封PPTP

    中国两大运营商都没有掐PPTP，一切正常。
    如果你是自己搭建的服务，不排除服务器IP被掐了，这种你换IP就行了。

    @kgen 但是我测试其他IP的PPTP也是无法连接上。（非小ISP，非移动）

    @KokongW 要不你来试试云梯，云梯的PPTP目前为止在全国各地没有被干掉，这样方便你排查是本地运营商问题，还是服务端问题。
    尝试完后，你如果不需要的话，3天内可以全额退款的。
