'How to make the connection between the broker and an external network?

I’m new in this field and I’m trying to create a device using arduino WiFi Rev 2 and the broker mqtt Mosquitto on an external network.

I’ve already installed Mosquitto on my PC and started it by the prompt. I changed the configuration file of Mosquitto in order to allow the listener on port 1883 and then run on prompt the command mosquitto -c mosquitto.conf -v and it worked.

But when I run netstat-a on the prompt, the port 1883 doesn’t appear on the address of the external network. What can I do to fix it ?

There’s the conf file I added

per_listener_settings true
listener 1883
protocol mqtt 
allow_anonymous true
listener 8083
protocol websockets
allow_anonymous true

Thanks for the your attention, hope to find a solution!

Solution 1:[1]

With the configuration you have provided, mosquitto will bind to ALL addresses, this will be signified by it binding to 0.0.0.0:1883 (and 0.0.0.0:8083)

So there is nothing to fix. Assuming no firewall/NAT between the Arduino and the machine running the broker it should just connect.
