"PPP&IPFW+динамический апйпи. Не могу разобраться с правилами."

Отправлено Pony , 19-Сен-03 10:59 
Господа, нужна ваша помошь. Имееться машина на диал-апе, с динамическим айпи, хотелось бы использовать её в качестве шлюза, что уже и делаеться, но на открытом файрволле(allow from any to any).
Нащёл пример конфига: http://www.freebsd.org/doc/en_US.ISO8859-1/articles/dialup-f..., но он не работает ни фига в моём случае. Что сдесь не так и где, черт возми, вписывать xl0(сетвуха).. Обязательно ли собирать IPFW2?

Спасибо. Не ругайте сильно ламера, я вырасту. :)

Выкладывай /etc/rc.conf, конфиги ядра и firewall, вывод dmesg.
Тогда покумекаем.
