Accepts everything from interfaces lo+. This needs to exist for local UNIX sockets to work. Used for R parallelization and similar inter-process communication.

There are pre-up and post-down statements added to /etc/network/interfaces to automate firewall management. Just edit and run /root/tables.sh. Changes will be saved to and loaded from /etc/firewall.conf
