Прошу помощи в диагностике и решении появившейся проблемы с VPN. До недавнего времени всё работало как часы, но потом появились проблемы. Причина мне непонятна, так как настройки соединения я не менял.
У провайдера VPN, запущенный на Windows. Имеем домашний компьютер: Linux debian 2.6.8-2-386 #1 Thu May 19 17:40:50 JST 2005 i686 GNU/Linux
поднят pppd с опциями

Нормально устанавливается соединение, прописывается маршрут в таблицу

Спустя 3-4 мин соединение падает, потом устанавливается вновь. В syslog имеем такие вот сообщения:
