Can a LAN port be configured as a WAN port?

Is it possible to assign a LAN port to serve as a WAN port on a Peplink Balance router? I know that this is possible on some other brands of routers but did not see such a setting so wondered if it was hidden somewhere or only doable from the command prompt?

Hi Todd, generally you can assign a WAN port to act as a LAN port but not the other way around. What model Balance router do you have and how many WAN ports do you need?
