One drawback here is that the remote access fails if the relay server is down even if the NAS itself can access the Internet without issues.Ĭonsumers also expect their NAS units to complement their accounts with public cloud services. The NAS OS keeps in touch with that relay server and transfers content using it as an intermediary whenever the relay server makes requests initiated by the device in the external network.

The mobile device / PC in the external network talks to that server using appropriate credentials.
A relay connection, on the other hand, involves an intermediate server operated by the vendor. However, port forwarding is not a fool-proof method, as certain network configurations might prevent the forwarding of certain ports.
Some vendors provide a dynamic DNS service so that consumers don't need to remember the WAN IP behind which their NAS is installed. This is the simplest and cheapest way for NAS vendors to provide remote access. Port forwarding involves opening up certain ports in the router and allowing incoming connections to be forwarded to the NAS. The first one is the ability to access the NAS content over the Internet / from an external network. The ubiquity of smartphones and rise in popularity of public cloud services such as Dropbox, Google Drive and OneDrive has resulted in some interesting consumer requirements in the NAS space.
