WireGuard Configuration Generator

This script helps you generate WireGuard configuration files for multiple peers and a gateway. It uses Python to automate the process of creating these files, which makes setting up a WireGuard VPN easier and faster.

How It Works

1. Generate Keys:

For each peer, the script creates a unique set of keys (a private key and a public key).

2. Create Peer Configurations:

Each peer gets its own configuration file with its unique keys and settings.

3. Create Gateway Configuration:

A special configuration file is created for the gateway. It includes all the peer public keys and necessary settings for the gateway.

Features

Automatic Key Generation: Uses python_wireguard to generate WireGuard keys. Config Files Creation: Generates configuration files for each peer and the gateway. File Storage: Saves configuration files to a specified folder in Google Drive.

Requirements

Python 3.x python_wireguard library (install with pip install python_wireguard)

How to Use

1. Prepare Your Environment:

Make sure you have Python and the required library installed.

2. Run the Script:

Open the script in a Python environment (like a Jupyter notebook or Google Collab). Execute the script. When prompted, enter the number of peers you want to configure.

3. Check the Output:

Configuration files will be saved in the wg_config files folder in your Google Drive.

Script Details

Functions

1. generate_key_pair():

Creates a private and public key pair for WireGuard.

2. create_config(peer_num, private_key, address):

Generates a configuration file for a peer with its private key and IP address. Saves the file in the wg_config files folder. The peer's public key is also stored in a list to be used later in the gateway configuration.

3. create_gateway_config(peers_public_keys):

Creates a configuration file for the gateway. Includes all peer public keys in the configuration. Saves the file in the wg_config files folder.

4. main():

Main function that runs the script. Asks for the number of peers. Generates configuration files for each peer and the gateway.

Notes

The PostUp and PostDown commands in the gateway configuration manage NAT rules using nftables. You can customize these commands based on your system's requirements. Make sure the folder path (/content/drive/MyDrive/wg_config files) is correct and accessible in your environment.
