手机连不上VPN,请教各位大侠.

skywing

我的VPN刚搭起来的时候手机使用移动CMNET接入点是能够正常连接的,今天起床后很诡异,怎么连也连接不是.就是连接了WIFI网络(家里的)也连接不上.(电脑上连接正常,就手机不行.)
查看了下服务器端的日志文件,如下

1. Nov 11 16:33:54 s1 pppd[28434]: LCP terminated by peer (MPPE disabled)

另外请教一事,PPTPD的运行记录文件在哪里查看呢?

LCP terminated by peer (MPPE disabled)

貌似不支持MPPE
但是手机上的时候强制要加密
看看手机上VPN的设置，把 “强制加密否则断开” （大概是这个意思） 这个选项去掉

s60?
ios?
andriod?

我把加密选项勾掉了也不能连接.奇怪了,昨天还好好的.
VPN支持MPPE的,电脑上的连接显示加密 MPPE 128.
