It would be good for there to be an option to set the WANEM server to act as a DHCP server for internal interface clients.
This would ease the adoption rate for development groups across a large enterprise that don't necessarily have network configuration knowledge.
This way, the external interface as a DCHP client and gets its configuration from the the network.
The internal interface should have default DHCP server to serve up IP addresses and DGs as well as DNS servers to the developer's workstation/pc.
It external interface could, as well, have default NAT to further ease adoption.
This is akin to the default configuration available from small office / home office routers from Linksys, Cisco NetGear etc.
