Virtual Domains in NAT/Route mode
By default, a Virtual Domain (VDOM) uses NAT/Route mode. In this mode, the VDOM is installed as a gateway or router between two networks. In most cases, it is used between a private network and the Internet. This allows the VDOM to hide the IP addresses of the private network using network address translation (NAT).
Each VDOM on a FortiGate can be configured for NAT/Route mode or Transparent mode, regardless of the operation mode of other VDOMs on the FortiGate. For more information about Transparent mode, see Virtual Domains in Transparent mode.
