NAT does not work

OS: CentOS Stream release 8
Kernel: Linux localhost.localdomain 4.18.0-536.el8.x86_64 #1 SMP Thu Jan 18 15:15:29 UTC 2024 x│

VirtualBox: Version 7.0.14 r161095 (Qt5.15.3)

I want to configure NAT.
In File -> Tools -> Network Manager -> NAT Networks:
NatNetwork 10.0.2.0/24, DHCP enabled (yes I know Nat network is not NAT in vbox glossary, but
but there is no a NAT tab).
Networking settings on the VM:
Attached to: NAT
Cable Connected is checked

Code: Select all

in the VM:                                                                                    
ip -br -c addr                                                                                
lo              UNKNOWN         127.0.0.1/8 ::1/128                                           
enp0s3          UP                                                                            
enp0s8          DOWN                                                                          
virbr0          DOWN            192.168.122.1/24                                              
virbr0-nic      DOWN   

as you can see, no ip address belonging to netowrk 10.0.2.0/24 is showing up by default

question: I am an absolute beginer in vbox; what shall I do so that I can have my NAT configuration working?

I am an absolute beginer in vbox

The best thing to do in this case is stick to the basics and get a working VM first, then start learning why it's doing what it's doing before changing things.

The VM by default uses NAT, not NAT Network. Did you try running the VM with the default NAT first?
