Всем доброго дня!
пытаюсь поднять ipsec vpn между srx210 и srx100h.
srx100 находится за устройством NAT, у которого время от времени (резерв) меняются внешние адреса, по этой причине полиси на srx210 "аггресивная" c "динамическим" хостом. А адрес внешнего интерфейса srx100 - 2.2.2.2. На пограничном устройстве NAT - проброшен ike до 2.2.2.2
пробовал и policy-based и route-based vpn - проблема одна и та же - в логах пишет No proposal chosenпроверил:
1. pre-shared ключи на обеих сторонах
2. наличие st0 интерфейса в политике ipsec
3. наличие st0 интерфеса в соотвествующей зоне!
конфиг прилагаю. большое спасибо всем
