MQTT CAD Ports

0weavern0weavern
in Local MQTT

Hi

I've got this setup and working really well however; I'd like to put the CAD on a separate network (I use this for most IoT devices). A firewall rule prevents communication between the normal and IoT LAN however; when I open up the two MQTT ports (1833 & 8883) the CAD cannot connect.

Looking at the logs, the CAD tries to call my MQTT broker but on some off ports (49500+).

Does anyone know if the CAD communicates on any other port to send the MQTT data beyond the standard MQTT ones?
