Novice:KNX_Easy with tunneling

Hello, I am a super novice, I am trying to get KNX_Easy to run but i miserably fail.
The problem is despite I install the package without errors and can create and deploy nodes, configured to talk to my IP interface (tunneling type) the KNX Easy nodes do not show errors in the console but also never get to connected state.
The only log message I get about KNX in console is:
[info] "2019-06-11T18:32:05.027Z" 'Loading knx: KNXnet/IP protocol implementation for Node(>=4.x), version: 2.3.3'
I would attach the full tracelog in trace mode but as new user I can't.
Any hint is greatly appreciated.
thanks
