Optional / legacy note: The official Vemcount firewall guideline also lists port 440 for older devices that cannot handle TLS above v1.0, plus additional services such as MQTT, FTP upload, VPN, and other device-specific endpoints. These are normally not required for a standard Brickstream setup unless specifically requested.
