Well here is my problem. My 920 works great inside the network but when I leave and check it remotely it stops working sometimes meaning, if I reset the DDNS from home it will work for about 12 hours then stop working again. I have opened ports 80-80 (maybe 80-81?) and setup my account with dlinkddns.com and triple checked the settings are right. I have turned on the DDNS through the webcam not the router. I am not sure about the DCHP settings or the UNPnp settings. I'll check when I'm home for lunch today. I think the IP is not updating but I can't be sure. BTW I'm running a d-link router as well, not sure what model.
