Здравствуйте, уважаемые специалисты! Прочитал кучу литературы, брал за основу много конфигураций файерволлов, но к сожалению ни интернет, ни почта (25-110) так и не заработали. Система установлена FreeBsd 7.2. Приведу пример ipfw.conf. Очень нужна помощь. Реально работает только ssh.

NetIn="10.17.13.0" # Внутренняя сеть

rc.config:

ifconfig re0= "xxx.xxx.xxx.xxx netmask 255.255.255.252"

остальное не буду...

сетевые карты рабочие. С сервера все пингуется и dns имена тоже, устанавливаются любые проги из портов. Прошу помочь.
