virtual box networking

Oracle Virtual Box
Centos

Hello Erman,

I would like to know the difference between NAT and NAT with Network? I have configured a VM for centos 7 using NAT.

I cannot ping 8.8.8.8.

My goal is to clone the VM so that each one can communicate with each other and they can access internet. IP will be obtained automatically. Kindly advise.

I checked below article:

Thanks,

The article that you follow seems good.

NAT mode means each VM is isolated behind its own router.
NAT Network is the same as NAT except that you can have several VM connected to the same internal router. So, NAT Network networking extends the NAT networking to allow multiple virtual machines to participate...
