С администрированием linux-систем еще не приходилось сталкиваться, потому и спотыкаюсь думаю. Man´ы вроде бы уже все причитал, но что-то не сходится. К сути. Нужно соединить локальные сети. Пока для теста объединить 2 локалки, в дальнейшем же потребуется объединить порядка 16 локалок.
Для центрального офиса думаю использовать шлюз на CentOS 6.3, на удаленных объектах шлюзы ZyWALL USG 50 и 100 (кол-во устройств-пользователей от 5 до 20).
Сделал следующее:
1) установил OpenSWAN:
yum install openswan2) сделал настройку:
2.1) /etc/ipsec.conf
# /etc/ipsec.conf - Openswan IPsec configuration file
