Next issue OpenVPN features:


Has OpenVPN 2.5.1 which means you can use CHACHA20-POLY1305 which can deliver enhanced performance for IoT devices and mobile devices, VPS – anything that doesn’t have AES-NI style hardware acceleration.


Despite having what seems like monthly firmware updates they are on 2.4.9.
