На Cisco 805 подняты два интерфейса Ethernet0 & Serial0 им присвоены IP в разных подсетях. Пинг с самой CISCO интерфейса Serial0 дает нулевой результат, а Ethernet0 пингуется отлично. Причем снаружи как с соединения через serial0 так и с соединения через Ethernet0 пинг обоих интерфейсов отличный. Таблица access-list пуста. Как можно заставить пинговаться Serial0?
