Version 7.2.3 sits in the “mature” zone of FortiOS. It is not the bleeding edge (7.4/7.6), but it is far more stable than the early 7.2.x releases. Build 1262 specifically fixed several annoying SSL VPN memory leaks and IPS engine crashes present in earlier 7.2 builds.
If you are running a homelab or a small production edge: 7.2.3 is a sweet spot. It supports Let’s Encrypt automation, ZTNA tags, and the new SSL VPN portal UI without the bugs of 7.0 or the feature churn of 7.4.
Yes for labs. You can snapshot, roll back, and clone VMs.
No for high throughput. A $500 FortiGate 60F has ASICs for IPS/SSL inspection. A KVM VM relies on your host CPU.
That said, a KVM FortiGate on a modern Xeon can easily push 2-3 Gbps of firewall + VPN.
