Всем привет.
В наличии есть маршрутизатор Cisco 2811. В настоящий момент по не известным мне причинам максимальное количество VPN подключений "15" где может стоять ограничение? Сразу говорю настраивал не я. Приходится поддерживать то что есть. Помогите настроить маршрутизатор убрать всё не нужное и оставить только настройки для VPN подключения.
