ioBroker.openhab

I reactivated this old thread because I wanted to install IoBroker on an old PI and use it in the same network. Frontail is using the port 9001 which is also needed by IoBroker so I can´t get IoBroker running.

Is it possible to change the port of Frontail or change something in the IoBroker side? I don´t know how to use both in the same network.
Thanks for any help.
