I have FTTP (Fibre to the Premises) and a GPON ONU given to me by my ISP. I know they can see hostnames and MAC of devices connected in ONU. If I connect my personal router to this ONU and then connect a PC to my personal router. Will they be able to see the Hostname and MAC of PC connected to my personal router ? When I go to ONU Admin Webpanel I see only the router hostname and MAC and don't see the devices that are connect to router, do they see the same ?
