May 15, 2017. I (Lyoungz) purchased the "Protectli Firewall micro appliance with 4x Gigabit Intel LAN Ports with 4GB RAM / 8GB mSATA" as a turnkey pfSense firewall appliance. After playing with pfSense some, I replaced pfSense with Vyos 18.104.22.168. It was a completely straightforward install. I prepared a Vyos live boot USB image, plugged it into one of the two USB ports on the device, plugged a USB keyboard into the other and a VGA monitor to the VGA connector, and booted right up into Vyos.
