So let's take a look at how this is taken care of.
Although you might think the configuration options to handle this would lie within the guest OS, it actually must be configured within the host. A big issue you will come across is making your virtual machines (regardless of platform) play well on your network's subnet. But not all is obvious for those enterprise users trying to make virtual machines, served up by VirtualBox, work within their network. VirtualBox is an x86 x86_64 virtualization product that is as useful to the enterprise as it is for the home.

In fact, there are virtualization solutions that can be had for free (unless you are going to virtualize a proprietary OS like Windows). But if you drop down from the clouds you will see there are actual virtualization solutions that can be had on the cheap. So much so, most small shops can't afford to make use of this amazing tool. Here's the problem -virtualization products can be quite expensive. Companies are virtualizing nearly everything. Ĭustomized network interfaces will be used on the host system for the host-only network, such as: vboxnet0.Virtualization is HUGE now. In this mode, communication between connected guest systems and the host system is possible. Communication with the host system or another network outside of VirtualBox will not be possible. Only those guest systems that have been connected to the same internal network will be able to communicate with each other in the internal network configuration. In this mode, the guest system will receive direct access to the network, to which the host system has been connected. Natnetwork is the name of the internal network.ġ92.168.15.0/24 represents the network and subnet mask.Įxample configuration with DHCP server VBoxManage natnetwork add -t nat-int-network -n "192.168.15.0/24" -e -h on Adding a DHCP server later VBoxManage natnetwork modify -t nat-int-network -h onįor more information and configuration options, see Network Address Translation Service (Virtualbox Manual). The internal network will be recreated if it does not already exist.Įxample configuration of a static NAT network VBoxManage natnetwork add -t nat-int-network -n "192.168.15.0/24" -e The name of the internal network is selected when configuring the NAT service. Virtual machines using this service should be connected to this internal network. The NAT service is connected to an internal network. Direct access to the client systems from outside the network is prevented and the guest systems can communicate with TCP and UDP over IPv4 and IPv6 to each other and to the outside world.
The functionality is similar to a router. Network Address Translation Service is a new NAT variant, which was newly introduced (experimental) with VirtualBox 4.3. If access should be possible, an additional interface can be configured using Host-only networking. Note: Even from the host system, the services on the guest system cannot be accessed. External access to the guest system (such as accessing a web server installed on a guest system) is not possible. NAT is the simplest option from the point of view of the guest system for accessing external networks. In this mode, the guest system will see a network card, whose (virtual) cable has been disconnected.
