Access WD from anyplaces

Does WD support connection access from anyplace which is outside and not only inside local network?
For example, the NAS is at office and i need to access it at home or anywhere in the world

No. You can’t use the service in North Korea.

You can access the NAS remotely pretty much anywhere else though.
