Wireguard aims for better performance and more power than IPsec and OpenVPN. Wireguard protocol passes traffic over UDP.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS.

I will show you through the step-by-step installation of the Wireguard VPN server on a Debian 11 (Bullseye).

Next, we download the .ovpn client file (you can use an SSH client with an integrated file manager such as Bitwise.) On Linux you can download the file with SFTP:

get client_config.ovpn

After that, start WireGuard and enable it at boot:

sudo wg-quick up wg0
sudo systemctl start [email protected]
sudo systemctl enable [email protected]

To establish the connection from the client to the server, on the client machine, install the Wireguard client and run the following command below to connect:

client sudo wg-quick up client_config.conf

Step 4. Firewall Configuration.

If you are using UFW, you will be required to allow port 51820 through the firewall:

sudo ufw allow ssh
sudo ufw allow 51820/udp
