Can someone check my router settings, is this a sign of mitm?

Hi, i need some help, i hope someone can help.
I checked my router. Everything seems fine, except the mac addresses. As you can see the last 2 digits of a mac address are changed. Is this normal or not? Is this a sign of a mitm?

You would expect the internet facing side to have a different MAC address than the LAN facing side as it is another adapter.

Quite a few routers allow you to use your computer MAC address as its own on the Internet side.

Are you referring to MAC address cloning?

actually, yes.
