Ran it for 1.5 years and it stepped away from it. Besides the fact that as soon as your host goes down or you do maintenance on your host, the network becomes kind of useless (ESP if you have multiple segmentated nets). The other thing to keep in mind is to pass through physical nics. Using just the vnics will potentially lead to security risks. That’s the reason I went back to physical fws.

Take a look at netbird or tailscale

For sure. It’s basically a NAS software appliance. You just need to bring your own x86 hardware. Truenas core was good, but they will stop actively developing soon in favor for scale.

I have it running both hardware (backup) as well as virtualized (with a special sas/sata card as PCI pass thru). Works like a charm.

Not to mention the sheer amount of security vulnerabilities they constantly have in their products. I never recommend QNAP for that reason. Out of the box solutions I only recommend Synology. Selfbuild route is uraid and my personal fav. Truenas scale.
