Connecting to AirVPN using WireGuard and a ThinkPenguin mini wireless router

These directions have been thoroughly tested on a TPE-R1200 and TPE-R1300 mini wireless router running libreCMC v1.5.8 and AirVPN with a WireGuard configuration (and many newer releases as well). WireGuard is similar to OpenVPN, but newer and faster. AirVPN is a privacy friendly VPN service that aims to protect your privacy and has support for WireGuard.

Please note that you will need to flash the latest release of libreCMC in order to install WireGuard packages from the libreCMC repository. The OEM images may already have WireGuard packages as of 1.5.8 so some steps below may not be required.

Note: If the links are broken below replace v1.5.8 with whatever the latest version of libreCMC is. You can find that out by visiting https://www.librecmc.org/:

Directions on flashing the above nor image are here (please note that the directions suggest flashing the OEM ISO version, but that will or may not work due to the need to install software from the libreCMC repository, utilize the image above instead): https://www.thinkpenguin.com/gnu-linux/vpn-mini-wireless-router-firmware...
