My desired use case involves sending MQTT data packets over a satellite modem from a datalogger, but otherwise using Cell WAN and WiFi WAN for remote device troubleshooting for that same datalogger.
I’ve set up a firewall on my Sat modem to avoid data use billing, and configured it with an IP address on the same subnet as the MBR1 mini.
If I understand correctly, all I would need to do is either port forward the port I’m using for MQTT, or
set the firewall rules to Allow only port 1883(8883for MQTTS) with the Sat Modem as the destination.
Is there anything else that I would need to consider/configure?
