iPhone 13 Router filter based on MAC for iPhone that its MAC address gets changed ?

[zillah]

Dear folk

I want to put time limits on my child's iPhone through my home ASUS Router RT-AX86U by using MAC address filter as per below snapshot which showing Clients name and Clients MAC address and I created excel inventory for each device at home and its associated MAC address, then I would know which device I can lock

Recently I realized that my iPhone13 (IOS 16.3.1) for example when is connected to WiFi 2.4GHz or 5GHz each frequency has its own MAC address no concern ,,,,,but MAC address changed for both frequencies when I compared them to my excel inventory !!!!!

if this is the case how can I implement a filter based on MAC address

Thx

MAC address blocking is by far the easiest to circumvent:

sudo ifconfig en0 ether 11-22-33-44-55-66

Either disable "use private MAC address" for in kids iPhone for your particular network so the phone uses a fixed address or make use of DHCP-ID and block by ID.

Both (and technically all) measures you take within your network will be rendered useless once your kid turns off wifi in their phone. I suggest parental controls to the rescue (also circumventable, but a bit harder, although the kids learn the ways in seconds).
