Are you looking for placing the entire VDI setup in 'PROD WAN' but having *only* the DC in DEV LAN ? Here placing th VDI means Broker, Agents and Clients. From which all network are you planning for client access to the VDI desktops ?
If you place broker, agents and a new DC in DEV LAN then making it accessible from DEV LAN or PROD WAN is pretty simple, but I think you are not looking for that, right ?
