Is VirtualBox NAT networking fundamentally different from VMWare NAT?

not under pressure

I'm trying to debug an issue and I've learned the difference between a NAT network adapter in VirtualBox and a NAT network adapter in VMWare Fusion. So far I can configure VMWare and achieve the desired result, but I cannot achieve this in VirtualBox. In a VMWare VM, I can use a NAT network adapter to achieve the following:

  • Visitors are assigned their own unique IP addresses
  • Guest can access external internet
  • The host can ping the guest and ssh to it
  • The guest can ping the host and SSH to the host
  • The guest can resolve (internal) domain names like the host

I thought I saw that in VirtualBox this is possible, but now I guess it's not possible. Maybe there is some option close to VMWare where I manually modify /etc/resolv.confin the guest to match the host's options? I did find some questions that seem to indicate that I should use bridged mode in VirtualBox, for example, the following question: Can't ping to VirtualBox instance , both answers seem to indicate that VirtualBox's NAT adapter doesn't support what I want Features:

Obviously, when you use NAT, it will not be possible to ping the host behind the NAT. This is how NAT works...even if you have a real non-vhost it will behave the same.

and

You need to change the network mode from NAT to bridged and ping should start working in both directions.

Also, the answer to this question seems to support the above: How to ping ubuntu guest on VirtualBox

Is it really impossible to ping the NAT adapter in VirtualBox from the host OS?

Yogi

I have used virtual boxes for many years and also have 2-3 years of experience in computer networking.

Yes, you can't ping a guest using NAT from the host in a virtual box, which explains how NAT works in real life. In real life, if you want to be able to contact a host behind a NAT, you have to set up a port forwarding rule where connections to a specific port on the router will be forwarded to a specific computer. This must be done on the router.

To enable port forwarding in a virtual box environment, select the Network pane in the virtual machine's configuration window, expand the Advanced section, and click the Port Forwarding button. Note that this button is only active when using the NAT network type – port forwarding is only required when using NAT ( http://www.howtogeek.com/122641/how-to-forward-ports vm and which acts as a server / ).
