WireGuard Client Setup Script

This is a minimal, interactive Bash script for configuring a WireGuard VPN client on Linux systems.

Features

• Installs WireGuard and necessary dependencies
• Prompts for manual input of all configuration values
• Supports split tunneling or full tunneling
• Optionally sets a custom MTU (or uses system default)
• Saves client PrivateKey in the config and PublicKey in a separate file
• Generates a standard wg0.conf under /etc/wireguard
• Optionally starts the VPN connection

Usage

chmod +x setup-wireguard.sh
sudo ./setup-wireguard.sh

What You’ll Need

• Client Private and Public Keys (pre-generated or managed manually)
• Server Public Key
• Server Endpoint (hostname/IP and port)
• Allowed IP ranges for split tunneling (optional)

Output

• /etc/wireguard/wg0.conf: WireGuard configuration file
• /etc/wireguard/client-public.key: Client's public key (for reference/server-side use)

Notes

• This script does not generate keys. You must supply your own.
• Designed for simple, controlled deployments (e.g., pre-registered clients).
• Tested on Debian/Ubuntu-based systems.
