Здравствуйте!
Помогите решить следующую проблему – не устанавливается тоннель между DFL-200 и Cisco PIX 515.
IKE устанавливается, а вот IPSec почемуто не работает

Хочу узнать почему не коннектится?
Время в группах вроде правильно стоит. Может в аксесс листе циски что не так?
Помогите плиз.

Еще вот Дебаг IPSEC

PS: да, и еще проблема – пинги от длинки до циски ходят, а наоборот нет. Где галку в циске поставить?
