no way guys... can't get this solved. If I configure the web access, when I save the setting it keeps forever with the progress indicator saying "saving data". On the other side, configuring web services access doesn't work either, as the nas is not registered at buffaloNAS.com.
looks like it can't register itself to buffaloNAS.com
should I set something in the router as well? such as port forwarding, NAT, or what?
