Привет!

Возникла проблема с доступом в интернет через l2tp посредством MPD 5
После нескольких неудачных попыток соединиться, MPD более не пытается это сделать,
хотя макс.кол-во попыток установлено в 0.

Вот что пишет в лог.  И так раз в несколько дней:

Маршрут к сети vpn серверов прописан статиком и не сносится. Фаервол для этой сети открыт.
В скрипте поднятия ифейса прописывается default, правила фаервола.
Все работает, но до какого-то момента. Несколько месяцев назад работало нормально
(но и адрес сервера был другой).

А вот полный лог с момента прошлого удачного подключения:
