Я тут впервые настраиваю шлюз (файрволл и нат, на машине также есть почтовый сервер, днс-сервер и веб)

При запуске скрипта выходит такое сообщение

Bad argument `бродкастовый адрес'
Bad argument `ACCEPT'
Bad argument `ESTABLISHIED,RELATED'
Warning: wierd character in interface `eth0-j' (No aliases, :, ! or *).
Bad argument `tcp_packets'
Warning: wierd character in interface `eth0-j' (No aliases, :, ! or *).
Bad argument `udp_packets'
Bad argument `ACCEPT'

Знатоки подобных вещей объясните где я не прав?

Вот сам скрипт
