The USG FLEX series are Zyxel’s powerful firewall products that have the precise protection, delivering high level of performance and security for SMB business networks. With the recent integration of USG FLEX firewall series into the NCC, Nebula cloud-managed platform is now further enhanced with zero-trust security network to Nebula users.

In this article we will discuss how to register a USG FLEX on the cloud with detailed instructions.

Starting from the NCC

To register a device, we can use the wizard when creating a new organization (refer to Figure 1-3) or you can add the device in the existing site on Site-wide> Add devices as shown in Figure 1-1. then run the installation process on USG Flex> Security gateway, as shown in Figure 1-2.

There are 2 options, one is “install USG Flex by myself” which means the system will send the installation mail to the current account, the other option is that you can specify the email address.

Once receiving the installation mail, you can prepare the scenario, as in Figure 7. Connect your laptop to the device Port 4 and WAN connection plugin to the Port 2, and please make sure the Internet is accessible.
After that, you can find the hyper link in the email, “click here or copy the link to your browser”, click it to start the ZTP process.

Please be aware that before the device going on cloud, you will need to “Reset” it to the factory default state; if not, you will see the message, as shown in Figure 9 and you can see the system LED become blinking green from blinking amber.

The other option is you can use the USB drive to run the ZTP process. There is a configuration file attached in the installation mail.  First, please make sure your USB is running on FAT32 and then copy the attached file in the USB root folder.

The same condition, mentioned in the above steps will apply. Make sure you have reset the device before plugging the USB drive to the USG FLEX first, then the registration process will run automatically. If you have used the console/SSH to the device, you can find the “ZTP json file in pen-drive” message, as shown in Figure 11.
