Part 1: Docker Container Setup

Understanding the binhex/arch-qbittorrentvpn Container

The binhex/arch-qbittorrentvpn container provides a complete qBittorrent solution with integrated VPN support. Key features include:

• Built-in OpenVPN client with automatic connection
• Integrated kill switch that blocks traffic if VPN fails
• Support for multiple VPN providers (NordVPN, ExpressVPN, etc.)
• Automatic IP leak protection
• Web UI access with configurable ports

Docker Compose Configuration

Create your docker-compose.yaml file with the following configuration:

docker-compose.yaml

services:
  qbittorrent-vpn:
    image: binhex/arch-qbittorrentvpn
    container_name: qbittorrent-vpn
    cap_add:
      - NET_ADMIN
    networks:
      - media-network
    ports:
      - "8085:8085"  # Changed from 8080 due to CSRF host issues
      - "6881:6881/tcp"
      - "6881:6881/udp"
    environment:
      - VPN_ENABLED=yes
      - VPN_PROV=nordvpn
      - VPN_CLIENT=openvpn
      - VPN_USER=changeme                    # Replace with your NordVPN username
      - VPN_PASS=changeme                    # Replace with your NordVPN password
      - VPN_OPTIONS=
      - LAN_NETWORK=192.168.8.0/24,192.168.9.0/24  # Multiple subnets (nginx on different subnet)
      - NAME_SERVERS=1.1.1.1,1.0.0.1
      - PUID=1000
      - PGID=1000
      - WEBUI_PORT=8085                      # Must match container port for CSRF protection
    volumes:
      - ./qbittorrent/config:/config
      - /media/merged:/media                 # Media directory
      - /media/server/Processing:/processing # Temp directory
    restart: unless-stopped
    labels:
      - "com.centurylinklabs.watchtower.enable=true"

networks:
  media-network:
    driver: bridge

Configuration Explanation

Key Settings

Setting	Purpose
NET_ADMIN capability	Required for VPN tunnel creation
VPN_ENABLED=yes	Enables the built-in VPN client
VPN_PROV=nordvpn	Specifies NordVPN as the provider
VPN_CLIENT=openvpn	Uses OpenVPN protocol
WEBUI_PORT=8085	Important: Must match container port to avoid CSRF issues
LAN_NETWORK	Multiple subnets for complex network setups

Port Configuration

Important: The container port and WEBUI_PORT environment variable must match to prevent CSRF (Cross-Site Request Forgery) protection issues. If you change the port mapping, update both:

ports:
  - "8085:8085"  # Host:Container - both must match
environment:
  - WEBUI_PORT=8085  # Must match container port

Network Configuration

The LAN_NETWORK setting supports multiple subnets separated by commas. This is useful when:

• Nginx reverse proxy is on a different subnet
• You have multiple VLANs or network segments
• Docker networks span multiple IP ranges
• Other containers (Radarr/Sonarr) need to access qBittorrent's WebUI

Note: If other Docker containers need to access qBittorrent's WebUI, include the Docker bridge subnet (typically 172.17.0.0/16) in your LAN_NETWORK setting.

Volume Mapping Consistency

Important: The volume mappings must match your other *Arr applications (Radarr, Sonarr, etc.) for proper integration:

# Standard *Arr volume mapping pattern
volumes:
  - /media/merged:/media                 # Media library
  - /media/server/Processing:/processing # Temporary/processing files

This ensures qBittorrent downloads are accessible to Radarr/Sonarr for post-processing and organization.

Environment Variables to Modify

Before starting the container, update these values:

# Required changes
VPN_USER=your-nordvpn-username      # Your NordVPN service username
VPN_PASS=your-nordvpn-password      # Your NordVPN service password
LAN_NETWORK=your-subnet-ranges      # Your actual network ranges

# Optional changes
PUID=your-user-id                   # Run 'id' command to get your user ID
PGID=your-group-id                  # Run 'id' command to get your group ID

Security Tip: Use Environment Files

For better security, store sensitive credentials in a .env file:

.env

VPN_USER=your-nordvpn-username
VPN_PASS=your-nordvpn-password

Then reference them in docker-compose.yaml:

environment:
  - VPN_USER=${VPN_USER}
  - VPN_PASS=${VPN_PASS}

Important: Add .env to your .gitignore to avoid committing credentials.

Part 2: VPN Provider Setup

NordVPN Configuration

The container supports multiple VPN providers, but this guide focuses on NordVPN setup.

1. Obtain NordVPN Credentials and Configuration Files

1. Log into your NordVPN account
2. Navigate to Services → NordVPN → Manual Setup
3. Select OpenVPN (not SOCKS5 for this setup)
4. Copy your service username and password (different from account credentials)
5. Download OpenVPN configuration files for your preferred servers

2. Place OpenVPN Configuration Files

After starting the container for the first time, it creates the necessary folders:

# Start container to create folder structure
docker compose up -d

# Wait for container to initialize, then stop it
docker compose down

# Place your downloaded .ovpn files in the config directory
# Copy your NordVPN .ovpn files to:
./qbittorrent/config/openvpn/

# Restart the container to use the new configuration
docker compose up -d

Important: The container needs the actual .ovpn configuration files from NordVPN to establish the VPN connection.

Optional: If you have multiple .ovpn files, you can specify which one to use:

environment:
  - OPENVPN_CONFIG=us1234.nordvpn.com.udp  # Specify exact .ovpn file to use

3. Supported VPN Providers

The binhex container supports these VPN providers:

Provider	VPN_PROV Value	Notes
NordVPN	nordvpn	Recommended, well-tested
ExpressVPN	expressvpn	Requires additional config
Surfshark	surfshark	Good alternative
Private Internet Access	pia	Popular choice
Custom	custom	Use your own OpenVPN config

4. Advanced VPN Options

You can customize VPN behavior with the VPN_OPTIONS environment variable:

environment:
  - VPN_OPTIONS=--remote-random --auth-retry nointeract

Common options:

• --remote-random - Randomize server selection
• --auth-retry nointeract - Don't prompt for credentials
• --ping 10 - Send ping every 10 seconds
• --ping-restart 60 - Restart if no ping response for 60 seconds

Built-in Kill Switch

Unlike manual UFW configurations, this container includes an automatic kill switch that:

• ✅ Blocks all traffic if VPN connection fails
• ✅ Automatically reconnects when VPN is restored
• ✅ Prevents IP leaks without manual firewall rules
• ✅ Works immediately - no additional configuration needed

The kill switch is enabled by default when VPN_ENABLED=yes.

Testing VPN Connection

Verify your VPN is working properly:

# Check container logs for VPN connection status
docker logs qbittorrent-vpn

# Look for these success indicators:
# - "VPN connected"
# - "qBittorrent started"
# - IP address from VPN provider's range

Part 3: Container Management and Configuration

Initial Container Setup

1. Wait for VPN connection: Monitor logs until you see "VPN connected"
2. Access WebUI: Navigate to http://your-server-ip:8085
3. Default credentials:
   • Username: admin
   • Password: randomly created
4. Find the Password

   cat ./qbittorrent/config/supervisord.log

5. Change default password immediately after first login

Container Management Commands

# Start the container
docker compose up -d

# Stop the container
docker compose down

# Restart the container
docker compose restart

# View logs
docker logs qbittorrent-vpn

# Access container shell (for troubleshooting)
docker exec -it qbittorrent-vpn /bin/bash

# Update container image
docker compose pull
docker compose up -d

qBittorrent Configuration

The container automatically configures qBittorrent for VPN use, but you may want to adjust these settings:

Connection Settings

1. Navigate to Tools → Options → Connection
2. Listening Port: Usually 6881 (already configured)
3. Use UPnP/NAT-PMP: Disable (not needed with VPN)
4. Use different port on each startup: Disable for consistency

Downloads Settings

1. Go to Tools → Options → Downloads
2. Default Save Path: /media/Downloads/Torrent (matches Radarr/Sonarr paths)
3. Keep incomplete torrents in: /processing/Downloads/Torrent/temp

Part 4: Advanced Configuration and Optimization

Performance Optimization

Optimize your container for better performance:

Resource Limits

Note: The deploy.resources section only works in Docker Swarm mode. For regular Docker Compose, use these alternatives:

services:
  qbittorrent-vpn:
    # For Docker Swarm mode:
    deploy:
      resources:
        limits:
          memory: 2G
          cpus: '1.0'
        reservations:
          memory: 512M
          cpus: '0.5'
    
    # For regular Docker Compose:
    mem_limit: 2g
    cpus: 1.0

BitTorrent Settings

1. Tools → Options → BitTorrent:

   • Enable anonymous mode: ✅ Checked
   • Encryption mode: Require encryption
   • Maximum active downloads: 5
   • Maximum active uploads: 3

2. Tools → Options → Speed:

   • Global maximum number of connections: 200
   • Maximum number of connections per torrent: 100
   • Global maximum number of upload slots: 4

Monitoring and Verification

1. Check VPN Status

# View container logs for VPN status
docker logs qbittorrent-vpn | grep -i "vpn\|connected\|tunnel"

# Check if VPN is working
docker exec qbittorrent-vpn curl -s ifconfig.me

2. Verify IP Address

1. Add a test torrent (like Ubuntu ISO)
2. Check the Peers tab to see connected IPs
3. Use online tools to verify your torrent IP:
   • Visit: https://torguard.net/checkmytorrentipaddress.php
   • Download their test torrent
   • Add to qBittorrent and check reported IP

3. Monitor Container Health

# Check container resource usage
docker stats qbittorrent-vpn

# View detailed container information
docker inspect qbittorrent-vpn

# Check container uptime and restart count
docker ps -a | grep qbittorrent-vpn

Network Configuration

Multiple Subnets

The container supports multiple LAN networks for complex setups:

environment:
  - LAN_NETWORK=192.168.1.0/24,192.168.9.0/24,10.0.0.0/8

This is useful when:

• Reverse proxy is on a different subnet
• Multiple VLANs need access
• Docker networks span multiple ranges
• Management interfaces are separate

Part 5: Troubleshooting and Maintenance

Common Issues

1. VPN Connection Problems

# Check VPN connection status
docker logs qbittorrent-vpn | grep -i "vpn\|error\|failed"

# Restart container if VPN fails
docker compose restart qbittorrent-vpn

# Check VPN credentials
docker exec qbittorrent-vpn cat /config/openvpn/credentials.conf

2. WebUI Access Issues

CSRF Protection Error: Ensure container port matches WEBUI_PORT:

ports:
  - "8085:8085"  # Both ports must match
environment:
  - WEBUI_PORT=8085  # Must match container port

Can't Access WebUI: Check LAN network configuration:

environment:
  - LAN_NETWORK=192.168.1.0/24,192.168.9.0/24  # Include your subnet

3. Container Won't Start

# Check container logs for errors
docker logs qbittorrent-vpn

# Common issues:
# - Missing NET_ADMIN capability
# - Invalid VPN credentials
# - Network conflicts
# - Permission issues with volumes

4. Download Issues

• No incoming connections: Normal with VPN, relies on outbound connections
• Slow speeds: Try different VPN servers or check VPN_OPTIONS
• Torrents stuck: Check if tracker allows VPN connections

Maintenance Tasks

Regular Updates

# Update container image
docker compose pull
docker compose up -d

# Check for new image versions
docker images | grep binhex/arch-qbittorrentvpn

Backup Configuration

# Backup qBittorrent configuration
tar -czf qbittorrent-backup-$(date +%Y%m%d).tar.gz ./qbittorrent/

# Backup docker-compose configuration
cp docker-compose.yaml docker-compose.yaml.backup

Log Management

# View container logs
docker logs qbittorrent-vpn --tail 100

# Clear old logs (if needed)
docker logs qbittorrent-vpn --since 24h

# Monitor real-time logs
docker logs qbittorrent-vpn -f

Performance Monitoring

Resource Usage

# Monitor container resources
docker stats qbittorrent-vpn

# Check disk usage
du -sh ./qbittorrent/
df -h /media/merged/

Network Performance

# Check VPN server location and IP
docker exec qbittorrent-vpn curl -s ifconfig.me

# Test basic connectivity speed (download test)
docker exec qbittorrent-vpn wget -qO- --timeout=10 https://speed.cloudflare.com/__down?bytes=10000000 | wc -c

Security Best Practices

1. Regular Updates: Keep container images and host system updated
2. Strong Credentials: Use complex VPN passwords and change WebUI password
3. Network Segmentation: Use Docker networks to isolate containers
4. Access Control: Restrict WebUI access to trusted networks only
5. Monitoring: Regularly check logs for connection issues or failures
6. Backup: Maintain regular backups of configurations and important data
