What MAC address is transmitted to the provider (or router, I don’t know)?

Question

Computer networks

So, dear essence of the question. We have a router connected to it via Wi-Fi with a MAC address xx:xx:xx:xx:xx:xx. The laptop has a virtual machine with MAC address yy:yy:yy:yy:yy:yy. Together they are connected via a network bridge. On a VIRTUAL machine, we surf the Internet. What MAC address is transmitted to the provider (or router, I don’t know)

Answer 1

- Packets are sent to the provider with the MAC address of the router itself
- Packets are sent to the router with the MAC address of the virtual machine

Answer 2

Read about the OSI model and how it works. Data is transmitted at the physical layer. Above it - channel. Each time a packet is transmitted between devices, the sender data is placed in the header and it turns out just the MAC address.
Answering the question - the provider sees the MAC that is on the external interface of your router.
