Quick Start: One-Line Installation

You can quickly set up WireGuard on your Ubuntu 22.04 server by running the following command:

Using curl:

Using wget:

wget https://raw.githubusercontent.com/Mailootje/Wireguard_Setup_Ubuntu_22.04/main/wireguard.sh && chmod +x wireguard.sh && ./wireguard.sh

This command will download the script, make it executable, and start the setup process.

Key Functionalities

• Install and Configure WireGuard: This option installs WireGuard, generates server keys, configures the server, enables IP forwarding, and allows you to add initial users. The script also installs qrencode for generating QR codes.

• Add Users: Adds users to the WireGuard server, generates a client configuration, and displays a QR code in the terminal for easy import into the WireGuard mobile or desktop app.

• Remove Users: Removes the user’s configuration and peer entry from the WireGuard server.

• Show Current Users: Lists all users currently configured on the WireGuard server.

• Restart WireGuard Service: Restarts the WireGuard service to apply new configuration changes.

• Check WireGuard Status: Displays the current status of the WireGuard server and active connections.

• Check IP Forwarding Status: Ensures that IP forwarding is enabled, which is required for routing traffic through the VPN.

• Install Additional Tools: Optionally installs useful tools like:

  • speedtest-cli (for testing internet speed)
  • nload (for monitoring network traffic)
  • s-tui (for monitoring system performance)

• Test UDP Port: Verifies if the UDP port used by WireGuard is open and accessible from outside.

• Fully Delete WireGuard: Completely removes WireGuard and all associated configurations.

Adding Users

When you add a user, the script generates a configuration file and displays a QR code for easy scanning and import into the WireGuard app.

Example Client Configuration:

[Interface]
PrivateKey = CLIENT_PRIVATE_KEY
Address = 10.0.0.X/24
DNS = 8.8.8.8

[Peer]
PublicKey = SERVER_PUBLIC_KEY
Endpoint = SERVER_PUBLIC_IP:51820
AllowedIPs = 0.0.0.0/0

The QR code will look something like this:

------------------------------------------------------------
Client configuration has been saved to /etc/wireguard/username.conf:
[...]
------------------------------------------------------------
