Same problem here, Just one day to another the router stop forwarding the ports of Enable Remote Management no mater what port I put it's doesn't work.
I have two routers in my network and the problem that I found:
1. Lan to External IP with the port: doesn't work
2. Lan to External IP second router port: doesn't work
3. From another Network to External IP with the port: Work.
4. From another Network to External IP second router to the port: Doesn't work.
If I put the same port to another computer works ok.
If I put the IP of the second router in the DMZ is work ok also.
If I ping to any unused IP for example 192.168.1.200 the ping respond.
Reply from 192.168.1.4: Destination host unreachable.
When the IP 192.168.1.4 is in use.
Why the address change?
All the other port is working fine.
Already reprogram the Firmware without success.
Hope some one can help my.

I can't get this to work either. My setup sounds almost like yours with 2 routers, but router2 is behind the dlink dir-655. hw rev B1, 2.11NA F/W. Router2 is to only extend or whatever main router. Mydlink.com is working just fine.
In fact, I can see in the "INTERNET SESSIONS" all my dlink cams phoning home to california, 52.8.x.x:443 and 54.193.x.x:443. BaMoh would be interested in that.
I do see this obscure entry in the log: notice May 29 23:35:11 client6_init: skip opening control port
I'm not sure if that is related to my issues.
