KNX software gateway

Hi everyone,
Has anyone here dealt with the topic of a software-based KNX net/IP gateway?

I’d like to set up or develop a KNX IP gateway on a Raspberry Pi to send KNX IP telegrams to it.
The desired functionality is straightforward: I send a message from a device via KNX net/IP directly to the Raspberry Pi, and it reads the message—nothing more.

BR.
