DEP problems when on 3G/4G

[lunddal]

We have a clustered setup with a JSS in the DMZ (no Distibution Point) set to Mobile Device Access Only in Limited Access.

If we try to register a new DEP-enabled device when on cellular network, it fails during the profile installation because of a network error.

It works fine when on our local WiFi, but it would be nice if users could activate when they are elsewhere.

Ports 636 and 3306 are open in to our local network, and port 8443 can be accessed externally.

Am I missing something?

Hello,

Can your devices register properly on external Wi-Fi networks? Do you have external DNS configured so that the DNS name being used resolves to an IP address where the DMZ can be reached externally?

[lunddal]

Yes, the external DNS points to the public IP of the server in the DMZ.

I will check if I can register the device on my own WiFi later today.

[lunddal]

No, it doesn't work on another WiFi network either.
