working with Debian 7.0
working with the examples at
https://wiki.debian.org/iptables
when i write a example for a lo0 table as shown
-A INPUT -i lo -j ACCEPT
and follow procedure of
iptables-restore < file-name
i do receive a message "line failed" for that line as shown above.
Question: do i need to config a file.
staying in the environment of the istalled Debian 7.0 and doing apropos loopback shows alsoloop.
doing internet searching shows a lot of info as if a bomb droped from the sky - but who knows if it is or could be debian 7.0 specific.
any assistance.
thank you
