Hi, I am trying to get the Tradfri binding running, but it always ends in a communication error. I am sure that the IP and the security code are correct (pinged IP, checked against MAC and c&p security code from QR code).

The only issue I can think of is that the OpenHAB server is in a different subnet. Routing between the two works, though.
Any other thoughts?

Hm, looking at other forums, people also have issues connecting via VPN. Some probably the gateway rejects connects from other subnets. Pitty. OpenHAB stays in the DMZ.
