Привет всем!!! У меня такая проблема - поставил фряху, пересобрал ядро с подержкой FIREWALL i NAT, у первого интерфейса 192.168.109.100 (NET) у другово 192.168.0.1(LOCAL). В rc.conf прописал всьо что надо (я так думаю 8)) тип фаэра ОPEN - но вот самоэ интересно что с интерфейса каторий смотрит в локалку я могу пинговать только интерфейс которий смотрит в NET a имено 192.168.109.100 - с любово ІР локалки (192.168.0.1,2,3,4,5,6). Почему не роботаєт инет??? Видь на самом сервере он єсть (192.168.109.1 - шлюз провайдера 192.168.109.5 ДНС) а вот в локалку попадпть не хочет...  Подскажите плиз чо не так!!!! Вот конфиги

# Define the firewall type in /etc/rc.conf.  Valid values are:
#   open     - will allow anyone in
#   client   - will try to protect just this machine
#   simple   - will try to protect a whole network
#   closed   - totally disables IP services except via lo0 interface
#   UNKNOWN  - disables the loading of firewall rules.
#   filename - will load the rules in the given filename (full path required)
#
# For ``client'' and ``simple'' the entries below should be customized
