Достался мне шлюз с почтовиком на борту...
по желанию хозяина - попросил убрать нат для внутренней сети дабы все ходили через прокси сервер.
Я попытался применить правило для единичного компутеря
#test
block log on $int_if proto tcp from 192.168.0.241 to any port 80

потом сказал
office# /etc/rc.d/./pf reload
Reloading pf rules.
No ALTQ support in kernel
ALTQ related functions disabled

(Судя по докам - ALTQ в моем случае не нужен - я не собираюсь зажимать канал.)

Так вот - указанный в правиле комп (192.168.0.241) продолжает ходить в инет- тоесть открываю браузер и тыркаю первую ссылку.

вот собственно хозяйство
