Starting with version 7.2.0, FortiGate VMs include a permanent evaluation license that does not expire but has significant performance and feature restrictions (e.g., low encryption strength, limited interfaces). System Requirements: Requires a minimum of 2GB RAM .
Deploying the v7,2,3 build brings a multitude of advanced, enterprise-grade networking and security capabilities to your virtualized environment: To get the best performance out of your
Once the VM is launched, open its virtual console. The boot sequence installs system files and automatically maps the available network ports.

For testing and verification topologies inside GNS3 or EVE-NG environments, follow these disk staging paths: GNS3 Staging Open the network simulator interface.
Deploying the virtual appliance successfully requires matching your hypervisor or simulation layout to Fortinet’s baseline resource specifications.
