Please refer to instructions at https://open5gs.org/open5gs/docs/guide/02-building-open5gs-from-sources/
Installing Open5gs on the same machine is very important because the "frame_ip4_address" in the AAR request via Rx interface takes received IP address and port in ims_qos module, hence, if the Open5gs is on a separate VM/machine, the IP and port received in received_ip and received_port values seen by Kamailio IMS will be the NATed IP of the Open5gs machine resulting in failing of AAR request.
