Run on kerlink: the program is not showing any packets received


I have installed the lora gateway bridge in my kerlink, however it seems that it does not capture the packet forwarder messages.

I have installed this packet forwarder: (Semtech one)

when I run tcpdump -AUq port 1700 I can see packets coming in the gateway but I see no packets logs when I start the lora gateway program:

INFO[0000] starting LoRa Gateway Bridge                  docs="" version=2.1.5
INFO[0000] backend: connecting to mqtt broker            server="tcp://"
INFO[0000] gateway: starting gateway udp listener        addr=
INFO[0000] backend: connected to mqtt broker

Any ideas how I can debug this? thanks!

Did you confirm that the packet-forwarder is sending its data to the LoRa Gateway Bridge? Somewhere in your configuration there is the following section:

    "gateway_conf": {
        "gateway_ID": "...",
        "server_address": "localhost",
        "serv_port_up": 1700,
        "serv_port_down": 1700,

Make sure that server_address is pointing to the IP / hostname of your LoRa Gateway Bridge instance. As you configured this service on the Kerlink gateway itself, this should then be localhost.
