Hi,

I have a DB1C Doorbell and the Ezviz Smart Wifi Chime.
My question is regarding the UPNP ports maps my Chime has opened up on my router.

I get that the Chime will connect to my internal Wifi so that when the doorbell is pressed the chime will sound but why does it need to open up these ports externally on by dynamic port mapping page of my router config ?
It basically opens up the same ports as the DB1C doorbell itself which I guess is so the app will ring on my phone when I away from my wifi but why does the chime need external internet access ?

Thanks
