I created a device and connect via tunneling to the bus.
It works now but every minute when the binding tries to connect to the interface again i get his messages:
2021-02-17 17:05:20.195 [ERROR] [Xnet/IP Tunneling 192.168.2.117:3671] - establishing connection failed, timeout connecting to control endpoint /192.168.2.117:3671
2021-02-17 17:05:20.199 [WARN ] [.core.thing.binding.BaseThingHandler] - Handler IPBridgeThingHandler tried updating the thing status although the handler was already disposed.
i am able to control the devices on the bus and read back values as well.
but i cannot get rid of this error messages.
i forwarded the port 3671 in docker and i had to set the parameter useNAT = true or i would not be able to establish a tunneling connection to my knx router.
it does not make any difference if i have the group monitor active or not.
this is how I start openhab in Docker (I am using also KNX):
I use knxd as the KNX router. This also run in a docker container:
i see you are using linux. unfortunately i cannot use the
parameter on mac os.
strangely it works but i am getting a connection timeout every time it tries to reconnect.
I will give knxd a try anyway maybe it solves my problem.
