Добрый день.
Настраиваю VPN IPSec туннель между маршрутизатором cisco 1841 и zyxel usg 50.
Туннель устанавливается без ошибок, пакеты шифруются. Проверяю на cisco
ping 10.0.3.1(адрес zyxel usg 50) so 10.0.1.1 (адрес cisco 1841) хост 10.0.3.1 доступен.
Однако, если пинговать ping 10.0.3.1 то хост 10.0.3.1 не доступен. В чем может быть дело?Cisco 1841
