Всем привет! Есть маршрутизатор cisco 891 на ней поднят GRE без шифрования. До смены провайдера все работало отлично. Старый провайдер закрылся (передал свои линии другому прову). Новый провайдер сохранил белый ip адреса, но сменилась подсеть с \27 на \25. Внес изменения в конфиг туннеля. Туннель и протокол в up, но трафик не бежит. Разговаривал с представителем провайдера, он уверяет, что все открыто все доступно. С маршрутизатора пингую все внешние адреса, проблем нет, но пинги не пролетают внутри туннеля на другой конец. На другом стороне стоит juniper к нему подключены остальные филиалы, все работают. Со стороны juniper мой белый адрес пингуют.

y.y.y.y - мой белый адрес
x.x.x.x - белый адрес конечного оборудования
