Key Features​

vpn-wizard.sh is a fully automated Bash script designed to set up a secure WireGuard VPN on Ubuntu-based systems. It performs the following tasks:

• Detects your main network interface and server IP address
• Generates server and client key pairs
• Creates configuration files (/etc/wireguard/wg0.conf and client1.conf)
• Enables IP forwarding and sets up NAT via iptables
• Generates a QR code for mobile client setup (via qrencode)
• Applies correct file permissions for security
• Installs required packages if missing (wireguard, curl, qrencode)
• Starts and enables the WireGuard service

The result is a fully functional, secure VPN setup with a ready-to-use client config — ideal for laptops or mobile devices.
