I made a setup with TRB245 with MQTT Gateway and using MQTT Broker of TRB245.
When using in my lan I can read/write modbus command by MQTT and this is working fine.
I tried to have remote acces by forwarding port external port 1883 to internal TRB245 IP, port 1883 but I can't connect to the broker anymore by client software. I already enabled "remote access" by broker settings.
Any help would be much. appreciated!
