KNX binding in docker on synology


I am trying to run OH in a docker container on my new DS916+ with the official oh2.3 snapshot amd64 debian image.

But OH cant connect to knx bus. I use the same configuration settings for knx binding as my running 1.8 instance. My Weinzierl 730 IP gateway can run 5 connections. All other instances which are accassing bus are stopped and I also restarted the IP gateway.
I also tested with localIp setting (host IP and 172.17.x.x docker internal IP), but it doesnt work.

Could anybody please share a working configuration?

solved by myself :sunglasses:

usenat=true should be set in knx.cfg
