Juniper туннель SRX IPSec к Microsoft Azure Dropping

Я немного озадачен и надеялся найти некоторое руководство здесь.

Я настроил туннель IPSec к Microsoft Azure от моего Juniper SRX240 (12.1X44-D45.2). Туннель хорошо работает, но отбрасывания фазы 2, когда нет никакого трафика, натыкающегося на туннель (не имеет значения, из которого трафик стороны происходит).

Я попытался играть вокруг с DPD, но Azure не поддерживает его. Я также настроил монитор VPN месту назначения на другом конце туннеля, но это также не работало. В моем "выставочном kmd журнала" я вижу P2 никакое предложение выбранные сообщения после того, как отбрасывание произойдет. Я должен добавить, что фаза 1 никогда не отбрасывает.

Это было бы в порядке, но к сожалению я должен статически направить удаленные диапазоны по туннелю и так как туннель не делает (и не может) иметь IP-адрес, мой следующий транзитный участок является st0.2. Когда фаза 2 отбрасывает, также - статический маршрут и маршрутизация следуют за следующим уточненным маршрутом. Таким образом, нет никакого способа возвратить туннель автоматически в это время.

Я был бы очень признателен за любой совет или помощь по вопросу. Мне нужен туннель, чтобы не лечь спать, даже когда нет никакого трафика, работающего на основе его. Посмотрите мою конфигурацию ниже.

Это - то, на что похожи журналы kmd.

Как я сказал, это работает отлично, пока нет никакого трафика, и я понятия не имею, что еще попробовать.

Заранее спасибо!
