KNX IP-interface loses connection over powerlan after restart HA

Third party integrations

Hi all

My KNX IP-interface loses connection with HA after a restart from HA.
This happens only when the IP-interface is connected over powerlan.
I have to use a long network cable to restore the connection and then I can reconnect over powerlan.
The strange thing is that I still get a ping reply but that’s it.

Does anyone have a clue what might cause this?
In the powerlan adapter there are no settings that might be related to this behavior.

TIA
Nick

Maybe the Powerlan adapter has some issues with forwarding multicast packets or uses its own subnet/ip range. These are the things Knx doesn’t like.

Ok, that explains it…
The adapters are configured in my LAN ip range though.

Thanks farmio!
