It works flawlessly with openvpn and wireguard. Just don't try to run surricata on it , the CPU is not powerful enough. But it easily handles 500mbps AES traffic with just over 25% CPU. (One core maxed out , due to openssl not multi threading). Its a old CPU (2016) and may be subject to Intel vulnerabilities and its a bit priced , but it comes with warantee which is an uncertain factor when buying Chinese Qotom. I basically paid 200 EUR extra for warantee and support. Now my little support question. Site says: "Unencrypted LAN: 940 Mbps" But I only get 720 Mbps using CAT6 cables and iperf3 LAN to LAN (receiving end is 2.5Gbps ) I wonder how the devs here got the 940mbps (the max speed for gigabit) directly on the cable. I hope I can tune this somewhere and hoping for an answer. The box is fine for 500mbps uplinks but for gigabit I would need to return it for a faster model, if I can't amp up the speed to the norm. But I trust I am probably making some error somewhere because the site says 940mbit so I guess they tested it
