In this tutorial, WireGuard and udptunnel are implemented on an Ubuntu Linux server and an Ubuntu Linux client. In the examples, the client is assumed to be at IP address 11.11.11.11 , and the server is assumed to be at IP address 22.22.22.22 . We will use port 1433/tcp for udptunnel and port 51820/udp for WireGuard.
