You change the setting from Auto to Manual by selecting the Configure link in your screen capture and proceed to setup the two ports for port forwarding. Then you setup port forwarding rules within your router to match the external port numbers you configured in the My Cloud.
There is another post made yesterday in this same subforum (My Cloud) that explains in general terms, on a first gen single bay My Cloud, how to enable/setup port forwarding for the My Cloud - Cloud Access service. The process may be relatively similar for the second gen v2.x single bay My Cloud but I don’t have access to a v2.x unit to check.
