> 3 dayInstalled and running pfsense firewall on this device, with no issues. As others have said, it runs warm (average of 48° c), but by adding a small fan, temperature is down to around 33° c.

> 3 dayThis is an incredible little firewall appliance! While a bit cumbersome to configure with pfsense there are really good guides and documentation available. I would strongly recommend the pfsense guide by NetworkChuck on YouTube for initial configuration.

> 3 dayThe box could have done with a convective heat transfer element since it feels a little hot for cloistered storage. The OPNsense initial configuration has some default assumptions but there is always the folks in Tech Support if you are not the type to read the manual online.

Greater than one weekThis is a great piece of hardware for running the OPNsense or pfSense firewalls. I installed the latest version of both operating systems on it without any issues. Its been running without any hiccups for several months now.

> 3 dayI got this directly from the vendor with OpnSense installed. Its a nice little machine. Much better that your standard router/wifi combo. I have my old wtr in ap mode now. Protectli has good customer support should you have an issue.

07-06-2025This is a nice little firewall box, I have Ubuntu Server 18.04 running on mine, acting as a firewall/router for my home network. For this purpose it works great.

> 3 dayPulled it out of the box, plugged in a VGA monitor and USB keyboard and Rufus bootable pfSense on USB. Took about 10 minutes and it was running pfSense. Ive had it running for about 48 hours and so far it is perfect.
