usb-tethering instead of real modem for WWAN

[OliverHeinz]

Is it possible to get FortiGate to use USB-tethering of an android smartphone instead of a real USB LTE modem  for  the WWAN connection? 

cdc_ncm driver is loaded, good

When I plug in the phone to my desktop, NetworkManager brings up the connection without further interaction and further configuration. My cable router can also use the phone as a fallback.

Any ideas how to make FG recognize and use the  usb-tethering?

Hello Oliver,

I have contacted one of our engineers and the answer is that it is it not possible to make FortGate recognized and use the USB-tethering.
