Unstble PPTP connections

ghanedan
Hi,
I am trying to connect remote locations via PPTP client modems to our astaro 6 box.

Altough the connection can be established, after a while the connections drop with the following log messages;

2007:08:16-12:15:54 (none) pptpd[2831]: CTRL: Received PPTP Control Message (type: 5)

2007:08:16-12:16:01 (none) pppd-pptp[3996]: Exit.

I observed the modems and their internet connection is always up and stable, so what may be causing this ?

thanks

    Ghanedan,

    You're telling:
    I observed the modems and their internet connection is always up and stable, so what may be causing this ?

    The log is telling you something else....
    2007:08:16-12:15:56 (none) pppd-pptp[3996]: No response to 10 echo-requests

    Could you set up a ping -t in the same time to see if that's true?
