SSH to the Dongle over WAN?

Hey Folks - If I get a dongle with 4G modem, is it possible to ssh to the dongle via wan? I guess somehow the 4G modem must dynamically assign an IP address and DNS configuration. If I knew the WAN-assigned IP address, could I ssh to the RaspberryPi?? Has anyone done this?

Hi @andyl,

It may be possible to get the IP, but typically this is a dynamic up and is closed to ssh login by your network carrier. What we recommend is that you install a VPN or something like ZeroTier on your device. This will give you SSH access.
