Добрый день. Настраиваю соединение Lan-to-Lan между головным офисом и филиалом.
Соединение устанавливается но через некоторое время падает и повторно не поднимается,
Пинги с обоих сторон его не поднимают. Момогает только перезагрузка модема в головном офисе.
Подскажите если сможете, уже незнаю что думать.
Вот схема

10.0.0.0/24              10.0.0.12 -Сisco2811- 192.168.2.100
