gluetun-qbittorrent Port Manager

Automatically updates the listening port for qBittorrent to match the port forwarded by Gluetun. This project is a fork of SnoringDragon's gluetun-qbittorrent-port-manager.

Overview

Gluetun can forward ports for supported VPN providers, but qBittorrent lacks the ability to automatically update its listening port to match this forwarded port. This script, available as a Docker container, checks every 30 seconds if the forwarded port file created by Gluetun has changed, and automatically updates qBittorrent's listening port accordingly.

Important Note

You need to add the provided docker-compose.yml configuration into your existing Docker Compose setup that includes Gluetun. Make sure to replace the default values with your specific settings. Otherwise, the script will not work properly.

Manual Test

Before using this script, ensure that qBittorrent is properly connected to the forwarded port. You can confirm this if you see a green globe icon at the bottom of the WebUI.

Setting Up Gluetun

Add a volume mount to your Gluetun container, for example:

volumes:
    - /docker/gluetunvpn:/gluetun

Then, add the following environment variable to your Gluetun container:

environment:
    - VPN_PORT_FORWARDING_STATUS_FILE=/gluetun/forwarded_port

This ensures that the forwarded port information is saved to the volume at /gluetun/. Without this setup, Gluetun will not create the file that stores the forwarded port.

Setting Up Gluetun-qBittorrent Port Manager

Ensure that the correct volume is set to access the forwarded_port file. In your Docker Compose file, add:

volumes:
      - /docker/gluetun:/tmp/gluetun

Within the container, this volume will be accessible at /tmp/gluetun.

Next, inform the script where to find the forwarded_port file by adding the following environment variable:

environment:
      PORT_FORWARDED: /tmp/gluetun/forwarded_port

That's it! With these steps completed, the script should be able to dynamically update the qBittorrent listening port.
