Народ, спасите. Блин мой конфиг не даёт зверям выход в нет, поделитесь
как наризаете и боретесь с флудом. В частности ipfw и ipf. А ?!
Совсем уже затуркался с этим ... неработает мой и всё ! У кого-то
работает у кого-то нет, могет natd непрально настроил, могет всё
непрально. fxp0 - inet, xl0 - local Ща примеры скину:
natd:
natd -f /etc/natd.conf -n fxp0
natd.conf:
same_ports yes
use_sockets yes
unregistered_only yes
dynamic yes
interface fxp0
далее ipfw в rc.conf

это только небольшой отрывок, файло большой там.

Может кто видит явные ошибки, тыкните носом. Блин, работает но
нестабильно, а уже всё что можн переделал, ещё эти выделенные IP
мешаются.
