Проблемы с настройкой iptables. Unknown symbol in module, or unknown parameter (see dmesg).

Всем доброго:

Пытаюсь начать работу и настроить iptables.
Руководствовался по выбору опций для ядра по ссылке: http://ru.gentoo-wiki.com/%D0%9B%D0%BE%D0%B3%D0%B8%D0%BA%D0%B0_%D0%B8_%D0%BF%D1%80%D0%B0%D0%B2%D0%B8%D0%BB%D0%B0_iptables

На форуме нашел тему с подобной ошибкой, но там у чела не было включена CONFIG_NETFILTER. У меня включена..
Но не работает. :(

В чем может быть дело?

Спасибо.
