Configure USG FLEX

There are two ways to configure the USG FLEX to link up with Nebula CC.  The email sent from Nebula will contain a *.json configuration file and a URL.  Below are instructions on how to setup the USG FLEX using one of the two available activation methods.

URL link

USB file

If the USG FLEX has been used in standalone mode please make sure to save a copy of the "startup-config.conf" file to a safe place (computer or cloud drive service).  Since the device mode is being changed from standalone to cloud mode, it will need to be reset to factory settings.  You can reset the device to factory settings by running the "system-default.conf" configuration file or pressing the physical reset button on the gateway for 15 seconds.
