debian 8.1 pptp клиент

Доброго времени суток. Проблема с подключением к pptp серверу. Постоянно отваливается соединение. Что интересно после перезагрузки могу подсоединиться, но после обращения к какому либо ресурсу в локальной сети соединение падает и больше не поднимается. Соединение настраивал через виджет KDE NetworkManager. Выхлоп debian: /var/log/syslog

P.S. С android и win подключаюсь нормально, соединение не рвется.

«Аналогичный» — это «разрывается соединение с тем же самым логом» или «разрывается соединение, но сообщения в логе немного отличаются»?

Всем спасибо, разобрался. Ошибка была в неправильно выставленном MTU главного интерфейса(железного). Он в NM стоял в «Авто», после уменьшения всё заработало. Обнаружил в логах запись аля: 

nm-pptp-service warn[decaps_gre:pptp_gre.c:331]: short read (-1): Message too long
А дальше по инструкции: http://droid-developer.blogspot.ru/2012/04/vpn.html
