A lightweight Windows tray application for toggling a specific IP blocking rule on/off using Windows Firewall — inspired by tools like Cloudflare WARP. Designed for personal network testing and experimentation.

• 🟢 Toggle Block: Right-click the tray icon or press Ctrl+F12 to enable/disable a specific Windows Firewall rule.
• 🎨 Tray Icon Status: Icon changes to indicate status (Power On = Active, Power Off = Inactive).
• 📌 Background App: Runs in the system tray without opening a window.
• 🚫 No full GUI: Interaction is via tray icon and hotkey only.

• Windows OS: This application is designed for Windows only, as it uses Windows Firewall (netsh) and Windows-specific APIs.
• Python 3.8+: Ensure Python is installed. Download from python.org.
• Administrator Privileges: The application requires administrator privileges to modify Windows Firewall rules. If not run as an administrator, the program will exit automatically.

git clone https://github.com/MrTomato77/TrustMeBro
cd TrustMeBro

python -m venv venv
.\venv\Scripts\activate
pip install -r requirements.txt

Ensure the icon folder contains power-on.ico and power-off.ico in the correct path (icon/power-on.ico and icon/power-off.ico).

1. Edit TrustMeBro.py:

   • rule_name: Name of the Windows Firewall rule (default: TrustMeBro).
   • remote_ip: Set to a valid IPv4 address (e.g., 192.168.1.1) to block outbound connections to that IP.
   • Note: Invalid IPs (e.g., 0.0.0.0 or x.x.x.x) will prevent the firewall rule from being created.

2. Run the Script:

   python .\main\TrustMeBro.py

3. Interact with the App:

   • Hotkey: Press Ctrl+F12 to toggle the firewall rule.
   • Tray Icon: Right-click the system tray icon to toggle the rule or exit the app.

Convert the script into a standalone .exe using auto-py-to-exe:

pip install auto-py-to-exe

auto-py-to-exe

• Script Location: Select TrustMeBro.py.
• Onefile: ✅ (enabled).
• Console Window: ❌ (window-based / no console).
• Additional Files: Add the icon folder (containing power-on.ico and power-off.ico).

The output .exe will be generated in the output folder.

Note: If you modify remote_ip or other parts of the script, recompile the .exe to ensure changes take effect. Run the .exe as an administrator, or it will exit.

• Administrator Privileges: The script or .exe must be run as an administrator to modify Windows Firewall rules. If not, the program will exit automatically.
• Valid IP Address: Ensure remote_ip is a valid IPv4 address. Using invalid values (e.g., 0.0.0.0 or x.x.x.x) may cause the firewall rule to fail.
• Use Responsibly: This tool is for personal network testing only.
