Fiber passthrough questions?

[Chris313AllNight]

So, I'm getting AT&T 2 Gig installed tomorrow afternoon and I'm planning to do the IP passthrough method, so I can use my AXE16000 and they say I need the MAC address of my ASUS router. Where would I look to find this?

The MAC address of Asus routers are usually on the back or bottom of the router with a whole bunch of information including WPS code. Or access the router GUI and see the Network Map System Status and the MAC addresses are listed at the bottom of the System Status column.
Edit to add: Example of information at bottom of router:
