Доброго дня!
помогите в решении проблемки:
есть сеть

|     лвс    |<--->| switch |<-->| switch |<-->inside| asa 5510 |outside<-->interenet
|1.1.1.0/24|      |1.1.1.1 |         |2.2.2.2 |          | 2.2.2.10 |

Юзеры из сети 1.1.1.0/24 и 2.2.2.0/24 цепляются на inside ASA по L2TP для доступа в интернет.Им выдаеются адреса из диапазона 3.3.3.0/24.

Все работает нормально.
НО не пингуются адреса интернета.

в Логах такое сообщение
ASA-1-106021: Deny ICMP reverse path check from 8.8.8.8 to 3.3.3.3 on interface inside

Вот кусок конфига ASA:
