Setup Kerlink Wirnet iStation on Chirpstack

Hello,
I would like to connect a gateway from the manufacturer Kerlink (Wirnet iStation 868) to a Chirpstack server (Chirpstack installation as described in Debian / Ubuntu - ChirpStack open-source LoRaWAN® Network Server documentation).
At Kerlink - ChirpStack open-source LoRaWAN® Network Server documentation
I can find instructions, but unfortunately they do not refer to a Wirnet iStation gateway.
Have any of you already had experience with connecting a Wirnet iStation gateway (instructions, YouTube videos, etc.)?

Thanks at all

You may try this guide.
You only need to change the LoRaWAN server and port to your LoRaWAN server and port.

You are looking at the Concentratord documentation, which is not required to install on the gateway. If you are using the Kerlink packet-forwarder, then you can just follow these steps:
