Can I build a closed network with multiple VMs and free5gc?

Q/A
#1

I am not good at English and use a translation app.
I apologize if I have expressed myself in a rude manner.

I used Oracle VM VirtualBox to build three machines: a machine with free5gc installed (IP:192.168.56.107), a machine running the Apache server (IP:192.168.56.109), and a machine sending requests to the Apache server ( IP:192.168.56.106), and the machine that sends requests to the Apache server (IP:192.168.56.106).

Join two machines to the free5gc network: the machine that sends requests to the Apache server (IP: 192.168.56.106) and the machine that runs the Apache server (IP: 192.168.56.109), and communicate using the free5gc protocol. How to do this?

free5GC is a 5G core network.
It speaks 5G protocols specified by 3GPP.
There’s no such thing as “free5gc protocol”.

I don’t see how free5GC is related to Apache server.

Thank you for your reply
I apologize for my lack of understanding.

My goal is to have free5gc communicate with multiple VMs.
