Any idea if a server can detect the MAC of my pc/router? If yes how can i hide it iwthout changing it every time? Thanks

TCP packets sent between the two will contain your MAC address.

Why are you trying to hide it?

Even if you sit behind proxy/vpn?

I'm not 100% on the details of how things like proxies and vpns manage your connections, but TCP protocol works on having source and destination MAC addresses in the packets.

Outbound packets will contain your routers MAC address and not your client PC's MAC, assuming you have a standard NAT/Router network layout.

You can change/spoof MACs but honestly there is no point.

EDIT:

If you use a VPN, servers will see the MAC of your VPNs gateway NIC.

I suppose the MAC of the router is what's visible not of the NIC right?

Yes, if you snoop on the internet you will see the MAC of your routers NIC.

Someone got banned from something and is trying to get around it.
