Hi,

im getting the error message "Bad argument '*mangle' when i try "iptables-restore < /etc/iptables.test.rules" from the shell, does anyone know what the problem could be?

if i comment out the '*mangle' section completely then i get the error message "Bad argument '*filter'. its probably some stupid syntax typo that i cant see (hopefully :p)

ive attached my iptables.test.rules file. (edit: hmm, attaching it didnt work, ive included it in the post below).

btw this file has been manaually created with nano, and not generated with iptables-save (im trying to follow the iptables part in the initial slice setup guide for ubuntu in the articles section).

Thanks :)
Colin-uk
