Thanks for replying!
So I need a static public IP address, from my wireless carrier Verizon, on my iPhone and iPad to get through a [non-Meraki] firewall.
I called Verizon, and they were able to assign the iPhone and iPad static IP addresses on their network immediately; however, the Verizon tech said I would need to download Apple Configurator and manually set the APN (access point network) on the two devices. I did not give one thought to what the Verizon tech said because I thought I would just assign this setting in Meraki. Unfortunately, I cannot find where to set the APN for my devices in Systems Manager.
These two devices have DEP assignments and MDM profiles from Meraki pushed to them.
I am not using and MX or MG router.
