tooltip icon There may be times the min/max values can change. An example for this is when the maximum memory for FG-VM00 changed between 5.2 and 5.4 from 1 GB to 1.5 GM. If that is the case, the settings for the VM will have to be manually changed to accommodate the new parameters.

After placing an order for FortiGate VM, a license registration code is sent to the email address used on the order form. Use the registration number provided to register the FortiGate VM with Customer Service & Support and then download the license file. Once the license file is uploaded to the FortiGate VM and validated, your FortiGate VM appliance is fully functional.

caution icon The number of Virtual Network Interfaces is not solely dependent on the FortiGate VM. Some virtual environments have their own limitations on the number of interfaces allowed. As an example, if you go to, you will find that Azure has its own restrictions for VMs, depending on the type of deployment or even the size of the VM.

FortiGate VM evaluation license

FortiGate VM includes a limited embedded 15-day trial license that supports:

  • 1 CPU maximum
  • 1024 MB memory maximum
  • low encryption only (no HTTPS administrative access)
  • all features except FortiGuard updates

You cannot upgrade the firmware, doing so will lock the Web-based Manager until a license is uploaded. Technical support is not included. The trial period begins the first time you start FortiGate VM. After the trial license expires, functionality is disabled until you upload a license file.
