I used my IP cameras to test these 2 external ports, which runs perfectly !!!
The reason why I would like to port forwarding is for the purpose of DDNS. It seems MyBookLive doesn’t support DDNS at all… However, no matter whether MyBookLive supports DDNS or not, Remote Access in MyBookLive settings are just like
Connection Status: Connected (Relay connection established)
Port forwarding failed to connect on port 8470 and port 8443 . (Error 31526)
If you are looking to use DDNS for you MBL from “Remote Access”, you might be looking in the wrong area.
The Remote Access is made to work with the WD2go feature. The port forwarding vs. relay connection has to do with the connection to your remote WD2go client.
What are you trying to accomplish through Port Forwarding?
