Установлен NAT + IPFW
Если установить ipfw_type="open", то все работает.
Но у меня правила на основе simple с некоторыми изменениями - вроде все должно работать, с локальной машины пингую и шлюз провайдера и его ДНС. Но в инет мой сервачок фряшный локальную машинку не выпускает, ни по 80 ни по 443 ни по 5190 портам. Да, и еще - у меня стоит авторизатор от провайдера - так этот гад меня не авторизует - возможно в этом проблема, хотя авторизация, как говорит провайдер проходит по 80 или 443 портам.
Мои правила:
