VirtualBox and VMware both create virtual machines with the NAT network type by default. If you want to run server software inside a virtual machine, you’ll need to change its network type or forward ports through the virtual NAT.

Virtual machines don’t normally need to be reachable from outside the virtual machine, so the default is fine for most people. It actually provides some security, as it isolates the virtual machine from incoming connections.

 

 

 

Selecting Bridged Networking

With the NAT network type, your host operating system performs network address translation. The virtual machine shares your host computer’s IP address and won’t receive any incoming traffic. You can use bridged networking mode instead — in bridged mode, the virtual machine will appear as a separate device on your network and have its own IP address.

To change a virtual machine’s network type in VirtualBox, right-click a virtual machine and select Settings. If you can’t click Settings, you’ll need to power off the virtual machine before making these change.
