Проброс почты во внутреннюю сеть

Непрочитанное сообщение Sallaxer » 2010-08-06 10:05:33

Здравствуйте.
Имеется проблема - не могу заставить работать почтовик (The Bat) внутри локалки.Все время пишут, что нет соединения с сервером
Имеем FreeBSD 7.2 ipfw + squid. Подключено 2 провайдера.
один комп вылазит в инет мимо squid (192.168.0.25) На нем почтовик работает, на всей остальной локалке - нет
Я никак не могу понять, что я не правильно прописываю и почему не хочет работать (прописываю в ipfw, т.к. мне кажется что squid это не касается)
