Home network users commonly deal with dynamic IP addresses that change unpredictably. This can be troublesome when using a VPN, as the IP can change at any time. Dynamic DNS solves this by running a daemon that updates DNS records whenever the IP address changes, creating the illusion of a static address.

Unfortunately the information on how to get WireGuard up & running and make the installation persistent after USG upgrades could not be found from one single place. This is why I decided to gather the data under this one post. ...
