I couldn’t find the guide to set the port forward up in the official wd site. Are there any users with this model of router managed to set up remote access?

The interface of port forward looks like the one in the link

Your router seems to support upnp so you don’t have to do the manual port forwarding. You could try the manual http://cdn.cloudfiles.mosso.com/c85091/WHR-G300N_Manual_web.pdf
