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
