Create a file called 'ApprovedNodes' or copy the template file (ApprovedNodes.template) and on each line, insert all known/valid mac addresses that belong on your network. The script will check this file as reference for known mac addresses.

example:

XX:XX:XX:XX:XX:XX (Device Name)

Once tested manual, set it up to run at your intended interval in cron.
