I see there’s also similar thread in community but no effective solution for this issue.
When trying to enable Remote Access, always I got Error 31520 and says there’s no internet connection. But actually in Dashboard → Network → LAN configuration, it displays Internet Access is good.
Also from MBLD console, ping www.wdc.com with no difficulty:
MyBookLiveDuo:~# ping www.wdc.com

UPnP has been enabled on my LAN gateway ( a Cisco RV180W)
I also see same problem on my friends MBL last sunday, so I doubt this may be WD’s software issue.
I’m afraid I found some interop issue between My Book Live Duo / My Book Live and some other brands’ router
The SSDP Discover sent out by MBLD cannot be responded by my Cisco RV180W router
While the SSDP interop between my Windows 7 laptop (192.168.1.208) and Cisco RV180W (192.168.1.1) is some kind of fine
Look into MBLD’s SSDP Discover message, it is very specific:
M-SEARCH * HTTP/1.1\r\n
[Expert Info (Chat/Sequence): M-SEARCH * HTTP/1.1\r\n]
Request Method: M-SEARCH
Request URI: *

MAN: “ssdp:discover”\r\n
MX: 2\r\n
\r\n
While Win7 SSDP Discover is relatively generic:
M-SEARCH * HTTP/1.1\r\n
[Expert Info (Chat/Sequence): M-SEARCH * HTTP/1.1\r\n]
[Message: M-SEARCH * HTTP/1.1\r\n]

I guess the similar situation happens on my friend’s TP-Link router. I do not have uPnP experience and the protocol document is very rare online, just mark this down. Does anyone have some idea about this?
