I have the same problem like french_guy. I can access my camera through mydlink.com from the local LAN, (the LAN where the camera is installed), but I can not access it from a remote location.
In my office, I have two LAN's. One is for test purpose. I call "the local LAN", the LAN where the camera is installed, and "the remote LAN" is the other one.
In my local LAN I have a Dlink DNS-320. This SAN is using port 80 in order to be accessed from outside of the router. The camera uses the same port 80. Dlink support changed the camera port from 80 to 1025, in order to avoid conflict with the SAN. Also, in the router, they created a port forwarding rule, pointing to the camera. The camera has private IP address 192.168.0.100, port 1025.
Everything works fine. From the remote LAN, I can type the router IP followed by port 1025, and I can see the Live Video from my camera, but when using mydlink.com from the remote LAN, I can't see the video.
I appreciate any help.
