BRI Mini- why can I not ping or remote access the BRI ?

is this a verizon issue or BRI issue?

Typically a mobile network doesn’t give you a public IP address you can ping or remotely access over the internet.

Instead you get a private IP in the range of 100.64.0.0 to 100.127.255.255 and they do something called Carrier Grade NAT (CGNAT) to reduce the number of public IP addresses they need to use for mobile devices.

Is your BR1 mini WAN IP in that Range above?
