Alert if a certain MAC is found in the local network

[IceCub]

Hello,

I'm trying to find a stolen laptop using it's WiFi MAC address. I have a network with a few (free) WiFi APs, for which pfSense handles the DHCP. Is there any way pfSense can alert me if a certain MAC address connects to the local network?

Thank you.

Try arpwatch package.

Thank you. This, combined with a mail forwarding rule solved my problem.
