AutoProxyConfig

AutoProxyConfig is a Python-based tool that dynamically detects the default gateway of your network and configures proxy settings on a Windows system. It is designed primarily for users who create proxy servers on their phones using apps like 'Android Proxy Server' or 'Every Proxy' to share their VPN connection. The tool resolves the issue where the server IP changes every time the hotspot restarts or is turned off and on again, ensuring a consistent proxy connection. It offers an automated solution, making it particularly useful for network administrators and developers looking to streamline their VPN proxy setup.

Features

• Automatically detects the default gateway IP address using the ipconfig command.
• Configures system-wide proxy settings in the Windows registry.
• Allows customization of proxy server address and bypass list.
• Simple and modular design for easy integration and enhancement.

Prerequisites

• Operating System: Windows (tested on Windows 10 and later).
• Python: Python 3.6 or later.

Installation

1. Clone the repository or download the script:

   git clone https://github.com/itskhawer/AutoProxyConfig.git
   cd AutoProxyConfig

2. Ensure Python is installed and added to your system PATH.

3. Install any required dependencies (if applicable).

Usage

1. Open the script in a text editor and modify the proxy_port variable if needed:

   proxy_port="8080"

2. Run the script using Python:

   python AutoProxyConfig.py

3. If successful, the proxy settings will be updated based on the detected default gateway.

How It Works

1. Default Gateway Detection:

   • The script runs the ipconfig command and parses its output to locate the default gateway IP address.

2. Proxy Configuration:

   • The set_proxy function modifies the Windows registry to enable proxy settings, set the proxy server address, and define a bypass list.

Script Overview

Functions

1. get_default_gateway()

   • Extracts the default gateway IP address from the network configuration.
   • Returns the IP address as a string or None if not found.

2. set_proxy(enable, proxy_address, bypass_list)

   • Configures proxy settings in the Windows registry.
   • Parameters:
     • enable: 1 to enable the proxy, 0 to disable it.
     • proxy_address: The proxy server address (e.g., 192.168.0.1:8080).
     • bypass_list: Addresses to bypass the proxy (e.g., localhost;127.0.0.1).

Example

Expected Output:

If the default gateway is 192.168.1.1 and proxy_port is 8080, the script will set the proxy server as:

192.168.1.1:8080

The bypass list will include:

localhost;127.0.0.1

Limitations

• The script is designed for Windows systems only.
• Requires administrative privileges to modify registry settings.
• Assumes a standard ipconfig output format.
