I do not think the links answer Skinny's question. He already owns a WD MyCloud Nas (which is a true NAS, Ethernet not USB) and wants to know if there are limitations the DIr-882 will place on accessing it from inside and outside his network.
I have an 882 and 2 NAS, both larger than 4TB. I have had no problems. Perhaps you could describe or link to the challenges you have heard about.
