Прошу помочь с таким вот вопросом- никак не пойму где неправ. Есть сервер (OpenBSD 4.6) который выполняет роль инет шлюза для небольшого офиса. На нем же запущен транспарентный Squid. На нем же запущен DHCP и OpenVPN (хотя и правильнее было бы вынести и сквид и опенвпн вDMZ но реальность такова). И никак не могу наладить связь между двумя офисами OpenVPN- нормально запускается на сервере, но связь не идет. Очень прошу помочь. Клиент в данном случае Windows XP. На стороне клиента файрволл отключен. С маршрутизацией сетей можно пока не парится - мне сейчас главное установить соединение. Вот конфиги
