Что имеем:
1) ASA 5512-x с 9.1 на борту, нас интересуют два интерфейса inside_old_local (192.168.0.35) и outside (193.211.40.x)
2) веб-сервер 192.168.0.8, слушающий 80-ый порт
Что хотим:
Пробросить порт 8081 внешнего интерфейса ASA (193.211.40.x) на веб-сервер во внутренней сети (192.168.0.
на порт 80, вроде классика, но вот с ASA - затык.Что знаем:
1) Подрезанный конфиг -

Drop-reason: (acl-drop) Flow is denied by configured ruleВсе статьи (привожу пару русских и последних, которыми пользовался http://cisco-ru.livejournal.com/348122.html и http://www.go-to-easyit.com/2013/07/cisco-asa-3.html) говорят что, чтобы NAT нормально работал (а проброс вообщем то NAT'ом и реализуется) нужно указывать в ACL именно внутренний адрес + внешний порт, диаграмма в ASDM тоже самое показывает
Вообщем, господа, нужен ваш хелп или советы где копать, ошибка наверняка глупая, но мешает сильно. Если не сложно - NAT тоже посмотрите, верно или нет, их в конфиге два (с портом 2323 - тестовый)
