[Comm] Проблемы с vpn

[some_x]

Здравствуйте. Может быть у меня руки искривляются при мысли о vpn под 
линуксом, может быть меня кто-то проклял на эту тему, но я в очередной 
раз не могу настроить vpn.
Итак, настройка под офтоп написана здесь:http://unlim.tomsk.ru/vpn.html.
Файлы /etc/ppp/peers/kvpnc.unlimited и
При попытке соединения:
    $ sudo service pptptunnel start
    Starting "kvpnc.unlimited" PPTP tunnel service: Using interface ppp0
    Connect: ppp0 <--> /dev/pts/7
    EAP: Identity prompt "Name"
    Modem hangup
    Connection terminated.

При этом в /var/log/info:

По какой причине происходит прекращение связи я что-топонять не могу, а 
играние с опциями ни к какому эффекту не привело, подскажите в чём может 
быть пролема.
