Nic1 is the number of the virtual network adapter VM_name is the name of your virtual machine In order to enable the NAT mode for a VM with VBoxManage, execute the following command: VirtualBox network modes – how the NAT mode works In VirtualBox IP addresses are not changed when the NAT mode is used, as you can see below: The default gateway for each VM is 10.0.2.2.

If you configure the network adapters of two or more VMs to use the NAT mode, each VM will obtain the 10.0.2.15 IP address in its own isolated network behind a private virtual NAT device. The default address of the virtual DHCP server used in the NAT mode is 10.0.2.2 (this is also the IP address of the default gateway for a VM). A virtual NAT device uses the physical network adapter of the VirtualBox host as an external network interface.

VirtualBox has a built-in DHCP server and NAT engine. The IP address of the VM network adapter is obtained via DHCP and the IP addresses of the network used in this network mode cannot be changed in the GUI. This default network mode is sufficient for users who wish to use a VM just for internet access, for example. A guest machine is not accessible from a host machine, or from other machines in the network when the NAT mode is used for VirtualBox networking. External networks, including the internet, are accessible from a guest OS. A guest operating system on a VM can access hosts in a physical local area network (LAN) by using a virtual NAT (Network Address Translation) device. This network mode is enabled for a virtual network adapter by default. Don’t forget to hit OK to apply changes in the VM network configuration.

You can tick/untick the checkbox when a VM is in the running state (see the screenshot above). Instead of using the Not Attached network mode, you can use any other network mode without ticking the Cable Connected checkbox. You can also check whether a DHCP client obtains the IP address correctly, whether the appropriate application can resume downloading after link interruption or packet loss, and so on. When you disable the Not Attached mode by switching to another network mode, the network connection becomes available again. For example, you can enable this network mode for a short time to emulate unplugging the cable. A virtual network adapter is installed in a VM, but the network connection is missing, much like when you unplug the Ethernet network cable when using a physical network adapter.
