Wan port spoof mac address auto changer/generator?

  • Is there a way to the spoof wan mac address on a pfsense box automatically on intervals? (every x days, or x gb download transfer which is preferred, etc)

    Some ISP's have a traffic watch that is bound to connected device eth port mac address and not to the modem itself. I was hoping to stay off Santa's naughty list by staying a step ahead.

    I found this page with a perl script: https://calomel.org/mac_random.html
    Not sure how to really trigger it though. Maybe a cron that polls incoming traffic on the hour to see if it goes above X?

    Any tips? Any reason to suspect the linked script being incompatible?
