Я немного озадачен и надеялся найти здесь руководство.
Я настроил туннель IPSec для Microsoft Azure от своего Juniper SRX240 (12.1X44-D45.2). Туннель работает нормально, но фаза 2 отключается, когда нет трафика, проходящего через туннель (не имеет значения, с какой стороны идет трафик).
Я пробовал поиграть с DPD, но Azure его не поддерживает. Я также настроил монитор VPN для пункта назначения на другом конце туннеля, но это тоже не сработало. В моем "журнале показа kmd" я вижу сообщения P2 без предложения, выбранные после того, как происходит отбрасывание. Я должен добавить, что фаза 1 никогда не падает.
Это было бы нормально, но, к сожалению, мне нужно статически маршрутизировать удаленные диапазоны через туннель, и поскольку туннель не имеет (и не может) иметь IP-адрес, мой следующий переход - st0.2. Когда фаза 2 прерывается, статический маршрут и маршрутизация следует по следующему более конкретному маршруту. Таким образом, в настоящее время нет возможности восстановить туннель автоматически.
Буду очень признателен за любой совет или помощь по этому поводу. Мне нужно, чтобы туннель работал, даже если по нему нет движения. Пожалуйста, посмотрите мою конфигурацию ниже.

Как я уже сказал, он работает отлично, пока нет трафика, и я не знаю, что еще попробовать.
Заранее спасибо!
Эта проблема звучит как проблема, с которой я столкнулся в туннеле IPSec VPN между Vyatta и Juniper SRX.
Вы пытались настроить в своем можжевельнике и в лазурном режиме обнаружение мертвого узла в конфигурации IKE на первом этапе согласования VPN?
В Juniper я знаю, что он включен по умолчанию, но, например, в Vyatta мне пришлось настраивать вручную, и это выглядит примерно так:
ike-group <IKE-GROUP> {
dead-peer-detection {
action restart
interval 15
timeout 30
}
lifetime 3600
proposal 1 {
encryption aes256
hash sha1
}
proposal 2 {
encryption aes256
hash sha1
}
}
Пожалуйста, дайте мне знать, работает ли это для вас.
