RAK 7258 with local Node-Red - No output at all

Hello,
my RAK 7258 gateway is up and running an I see the packets of my nodes on TTN.

I would like to check if other nodes are using my gateway. So I tried to setup a simple MQTT connection in Node-Red using the IP address of the RAK 7258. No extra configuration on LoRa Gateway MQTT Bridge, so no SSL/TLS at all. As soon as I deploy I see a Connected but even with a wildcard topic ("#") I don’t see any debug output. The gateway and the Node-Red server are on the same local network.

I just want to be notified if my gateway sees a device address for the first time.
Thank you, Tore

Hello,
to simplify my question:
Is it possible to forward all packets to TTN (The Things Network) and to use a local MQTT broker and/or Node-Red at the same time? If the answer is yes, what do I need to configure?
Thank you, Tore

lt is supportive, I will send a usage document to your email, please pay attention to check.

Hello,
seems that I should mention that I’m looking for all packets (from other and from my own nodes) that reach my gateway.

A first test with a pax counter on an ESP32 and Node-Red already worked.
Thank you, Tore

Hello,
I was told that a connection to TTN (via Semtech UDP) and to Node-Red (via MQTT) is not possible.

I will ask TTN how to get some gateway statistics.
Thank you, Tore
