Соединение VPN из Ubuntu 14.04

таким образом, проблема в основном, который любая попытка подключить к моему офису VPN приводит к сбою в Ubuntu 14.04.

Нет никаких специальных настроек, но стоящих упоминания, что это к PPTP.

Я могу проверить с помощью ping-запросов сервер достаточно легко. Я не уверен, какую информацию я могу поместить здесь для создания этого более диагностируемым, но сообщите мне.

Вывод следующие:
