Gateway MQTT Ethernet with the 2.3.0 library

[miclane]

Hello,
I just tried version 2.3.0 with an MQTT ethernet gateway.
The gateway connects well to the broker MQTT but when the nodes send information the gateway does not return anything to the broker.
With version 2.2.0 it worked without problems.
An idea ?
Thank you.
