привет всем
есть циска 1841 к ней на один из интерфейсов подключено несколько удаленных точек (IPSEc)
так вот: переодически то с одним то сдругим узлами возникает проблема прохождения трафика больших (нормальных) размеров - не проходят даже пакеты 50 байт
Решается все пока перезагрузкой роутера 1841.После этого на некоторое время все нормально работает - потом повторяется старая картина. Что это может быть..... подскажите плиз.
На ужаленных точках Cisco 851ниже кусок конфига 1841
