Introducing virtual domains

Virtual Domains (VDOMs) enable the division of a single FortiGate unit into multiple virtual devices. Each VDOM supports separate settings related to routing, firewalling, and VPN connections. Also if we have decided not to use VDOMs, a virtual domain will always exist: the root VDOM, which is the one we use forthe normal management of a FortiGate unit. As soon as we adopt VDOMs, the entire existing configuration will be kept inside the root VDOM. To enable VDOMs we have to use the Virtual Domain options, shown in the following screenshot, by navigating to the System | Dashboard | Status menu:

On selecting Enable we will be forced to login again to the FortiGate unit. As soon as we open the web-based manager, we will see some changes. The first one is that the left pane is no longer called System but is now called Global. We will see an additional menu dedicated to VDOM configuration. Both changes are shown in the following screenshot:

From now on, only accounts...
