Inter-VDOM links between NAT mode and Transparent mode VDOMs
FortiOS 5.0 supports inter-VDOM links between NAT and Transparent mode VDOMs. No special configuration is required and you can create an inter-VDOM link between NAT and Transparent mode VDOMs in the same way as creating an inter-VDOM link between two NAT mode VDOMs.
