↑ That is a QR code containing the client configuration.

Finished!

The client configuration is available in: /root/webdock.conf
New clients can be added by running this script again.

Use your VPN

WireGuard client software is available for Android, iOS, Windows, Linux etc.

For Linux, you can simply install it using apt.

sudo apt install wireguard

Download the Client Config File to your Local Machine

You can download the file using Scp, Netcat or Python, but Python way is the easiest.

# cd /root && python3 -m http.server

Sample output:

Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

Go to your web browser and enter your Webdock server’s Public IP Address with the port number 8000 i.e, http://XX.XX.20.90:8000/, and download the webdock.conf file.

Conclusion

In this article, we’ve successfully set up our own private VPN using Webdock Ubuntu server. If you want to learn more about WireGuard, you can read the official documentation here: https://www.wireguard.com/

As an alternative, if you do not want to set up a VPN yourself there is a wide range of VPN companies which you can use to get a fully managed service.
