vpn over pppoe, регулярные обрывы pptp

[nanacano]

Добрый день
У меня следующая проблемы: 1) происходят регулярные обрывы pptp, при чем система этих обрывов мне не ясна. 2) после обрывов соединение не устанавливается по новой не смотря на мои настройки
У меня настроено pppoe + pptp соединение.

Соединение поднимается следующим образом:

Код Выделить Развернуть

pptp <xx.xx.xx.xx> call provider

где <xx.xx.xx.xx> адрес сервера подключения

После этого появляются 3 процесса в системе:

  783 ?        Ss     0:01 pptp <xx.xx.xx.xx> call provider


Вот с какими настройками я запускаю:

Через определенное время (если шлюз проработал долго то может сразу) это соединение как бы разрывается. «Как бы» потому что прекращает работу только один процесс, но не смотря на установки persist и maxfail 0 этот процесс не восстанавливается.
Вот что остается в процессах:

И так далее, видно что шлюз пытается поднять соединение но не может.

Соединение работает в целом хорошо, за исключением разрывов.
Подскажите как устранить разрывы и как настроить чтобы соединение восстанавливалось.

ты бы нормально обьяснил,как у тебя сеть устроена.
как настраиал ?

[gardarea51]

Я настраивал вот так: https://debianforum.ru/index.php?topic=4708.msg41428#msg41428
Работает сутками, не падает..

ты бы нормально обьяснил,как у тебя сеть устроена.

Конфигурация: с одной стороны (eth0) шлюза мы имеем шифровальное устройство vipnet и локальную сеть, с другой стороны – подключение к сети провайдера (eth1).

Подключение к интернету производится через pppoe. Это соединение работает нормально. Вот настройки, файл options :

Локальную сеть надо соединить с корпоративной, чтобы это сделать используется пакет pptp-client. Корпоративная сеть находится в том же городе и подключена через того же провайдера с pppoe подключением. То есть можно сказать vpn строится поверх двух pppoe подключений.

маршруты корпоративной сети шлюз получает посредством quagga. Настройки могу привести если нужно.
Проблемы 2:
1.Есть случайные регулярные разрывы pptp.
2.После разрывов соединение не восстанавливается (один процесс исчезает и не появляется снова), хотя по идее должно.

Если шлюз работает долго то сразу после подключения он может отрубить соединение:
