KNX IP/Gateway

Hello OpenHAB comunity,

About 1 month ago I bought a Raspberry Pi 4 with 4MB RAM and 32GB of SD memory, ans Raspbian OS and works perfectly.

Just I’m learning about openHAB and it’s great. I read a lot of information but I have a problem for configure the KNX/IP Gateway.

I tried put the system un Router and Tunnel mode, with NAT on and off, and others and nothing.!

I checked my IP Host, and comunication with knx device (JUNG IPS300SREG) with a ping and works well.

HOST: 192.168.0.30
KNX: 192.168.0.61

Here you have the configuration of KNX device

But always I have the same result… UNKNOWN
Some times put STATUS: OFFLINE - COMMUNICATION_ERROR

Here you have my openHAB version:

openHAB_version

I don’t know if only configuring the THINGS in the BUILDING is enough, or I need to download any file into the raspberry (knx.thing).

Thank you for your help and suggestions.

Best regards.
