This will insert a default adapter including the type, connection, MAC address and cable. To ‘add’ a network adapter to your virtual machine just select the Enable Think of the first four adapters provided in the desktop interface as empty controller slots in the virtual machine. Either way, you’re probably going beyond the scope of this primer. When you reach five or more NIC’s for one virtual machine, you are either building an industrial strength production environment, or your experiments in networking are going seriously deep. An additional four NIC’s can be configured from the command line using the VBoxManage modifyvm command in a terminal session. You can configure up to four Network Interface Controllers from the Network tab of the virtual machine settings. It’s just like adding a network card and extra protocols to a physical machine. It is not a disaster if it is not ‘right first time.’ Indeed, as requirements change – say you need to add additional services or allow external access – you can modify the networking support without having to junk or rebuild the virtual machine.

The beauty of VirtualBox networking is that it can be modified and added Depending on the type of access you should select one or more adapters with the appropriate Networking option to support the network access needed. You should consider the use case for the Guest(s) you are running and determine what is the best single or combined Comparison of VirtualBox Network Modesīefore we go through each of the available networking modes, let’s look at a quick comparison of the types of access they support. Port forwarding can beĬonfigured for external access to virtual machines whose networkĪdapters operate in NAT or NAT Network modes.

The Attached to network mode and Adapter Type by changing the MAC address of each virtual NIC, and plugging or unplugging the virtual networkĬable – Cable Connected. VirtualBox network adapter advanced settings allow you to qualify Figure: Network adapter advanced properties
