How to forward a spoof mac address from client on router?

[Starbuck99]

I have a AppleTV with a fixed mac address.
I also have a Asus RT-AC86U router.

How can I spoof the AppleTV mac address to the WAN?
E.g. Mac Address of Apple TV is X - I want the outside traffic to see AppleTV Mac Address as Y - using the router to assign the spoof MAC address to outside traffic?

Reason.... we have a paid streaming subscription which only allows 3 devices. Devices are locked on the Mac Address.

In order to add a 4th device the AppleTV needs to have the same Mac Address as one of the other 3 authenticated devices.

Any help is appreciated.

Thank you.

You can "clone" any MAC address you want onto the WAN interface by using that option in the router's GUI. But MAC addresses only exist in their local network so the only thing that will see it is the ISP equipment your router or modem is connected to. If Apple are restricting their services based on the client's MAC address they're not picking it up from the WAN interface (or the router), they must be picking it up in the application software. So you would have to "hack" the application.
