![]() ![]() In VirtualBox, you can set up NAT by selecting the virtual machine, navigating to Settings à Network à Adapter# à Attached to and then choosing NAT from the dropdown. However, it is possible to set up port forwarding to allow the outside world to connect to the guest OS on certain services. This provides a level of protection since virtual machines are hidden from the external network. Note: Technically speaking, this is more like PAT since all the virtual machines connect to the outside using one IP address – the host OS’s IP address.Īs with normal NAT (dynamic NAT or PAT), the external network is unaware of the private network and as such, cannot initiate connection to the virtual machines. When I use the term “external network,” I mean any network outside the guest OS, such as a LAN to which the host is connected, the Internet and so on. This means that the external network sees traffic from virtual machines as though it came from the host OS itself. It also listens for returning traffic so that it can send it to the required virtual machine. The NAT device/engine usually sits between the virtual machine and the host and it translates packets from the virtual machine to the IP address of the host. The NAT network type does exactly what you will expect it to do: the virtual machines are on a “private network” but can connect to the “external network” using the IP address of the host OS. VirtualBox supports more such as Internal Network, Generic Driver, and so on, but we will restrict ourselves to the three main types. Generally speaking, there are three main virtual networking types/modes: NAT, Bridged and Host-Only. The VirtualBox is installed on my laptop (Windows 8 OS = host OS) and I also have several virtual machines in there but for this article, we will be using my Windows XP virtual machine (guest OS). This article assumes you have already installed a guest OS.įor this article, I have Oracle’s VirtualBox installed (it’s free!) but the concepts we will discuss here also apply to other software such as VMware Workstation. A guest OS is a virtual machine running in the virtualization software. ![]() Note: The host OS is the physical machine on which you will install VMware, VirtualBox, etc. For example, how can you connect your guest OS to the Internet connection available on the host OS? In this article, we will discuss the various network types available for virtual machines and see how each type can be used. With such a wide compatibility matrix, you can use it virtually in any platform which has a HTML5 browser available.One of the areas less understood by people learning to use virtualization software such as VMware, VirtualBox, etc., is that of virtualized networking. Use case scenarios for WSX are only limited by your imagination. WSX enables you to use the touch screen of a tablet or a smartphone to interact with your virtual desktops. With these features you can access your data and virtual machine on the go using WSX through the convenience of a web browser. This feature requires a HTML 5 capable browser but most modern browsers support this now.Īs the world moves towards mobility, more users prefer using tablets and smartphones to accomplish work functions. You can use the virtual machine in the web browser just as you would through the Workstation user interface. Select the shared virtual machine to view it in the browser. You can also use the Add a Server option and connect to your vSphere/ESXi setup to access the virtual machines running there. It will request the login credentials again. On the welcome page, select the Shared VM (localhost) option.
