      I'm noticing that our pfSense firewall keeps moving the MAC address for a macOS machine between the ethernet and wifi adapter. This appears to be happening because teh pfSense box will update the ARP table due to an ARP request from the macOS machine. Is it possible to disable this and only learn MAC addresses from ARP responses?

        ????

        Are you moving that Mac between the 2 connections? How is your network set up? Do you have the Wifi and Ethernet on different interfaces? If so, why?

        I haven't lost my mind. It's around here...somewhere...
