#7 l2tp server disconnect

[Jalindar]

Hi ,

I tried 0.4 version of rp-l2tp for server setting but when I try to connect using Windows 7 or Android phone then tunnel disconnections in few seconds.

I got setting information from here..

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

from log I can get that tunnel is connected and then disconnect.

I can set is server IP, user, password and secrets on the Windows 7 and Android Phone.

Error on Windows 7 says Error 800, sometime Error 868. On Android phone, it says VPN disconnected and then window popup with error saying user or password not correct but i have set correct both.

Any guess, whats going wrong.

Thanks in advance.
