When connection from a home network, it's my understanding that the router's MAC address, not the computer's MAC address, is revealed beyond the home network (e.g. to the ISP). When using a VPN, can the ISP or VPN provider see/log the router's MAC address? In the case of TOR, who would be able to see/log the router's MAC address? I found a few threads here that discuss a similar topic, but can't find the answers above.
