Proper firewall configuration ensures Deluge functions correctly while maintaining system security.

Opening Required Ports

Configure firewalld to allow Deluge traffic:

sudo firewall-cmd --permanent --add-port=8112/tcp
sudo firewall-cmd --permanent --add-port=58846/tcp
sudo firewall-cmd --permanent --add-port=6881-6999/tcp
sudo firewall-cmd --reload

These commands open the web interface port, daemon port, and torrent traffic range permanently.

Security Considerations

Limit daemon access to trusted networks when enabling remote connections. Consider using VPN access for additional security when managing Deluge remotely. Regularly update firewall rules to reflect changing network requirements.

Network Troubleshooting

Verify port accessibility using netstat or ss commands to confirm services are listening on expected interfaces. Test connectivity from remote machines to ensure firewall rules are functioning correctly.

Initial Configuration and Optimization

Proper initial configuration maximizes Deluge performance and ensures smooth operation within your network environment.

Connection Manager Setup

The connection manager appears on first launch, requiring daemon connection configuration. For local installations, connect to the default localhost daemon. Remote installations require specific IP addresses and authentication credentials.

Download Directory Configuration
