OpenWRT – WireGuard VPN

OpenWRT supports WireGuard! So why not use the VPN services on all your devices when you are not at home to use your own adblocker and other services you run on an OpenWRT device and have access to your local network.

The setup of the WireGuard server is not really difficult and straight forward.
