FurryNutz asked me to comment:  Unfortunatly, I am only using a dynamic dns service and port forwarding on the router to the camera; not the mydlink service.  The camera replies with a login page requesting the camera's user name and password.  I supply those (using linux and firefox), and it shows the camera image.  It is not a video, but rather a still image.  This is sufficient for my needs, since it is only to monitor the temperature of the plenum on my furnace.  I have wondered if I enabled java, if the camera would stream video, but to tell the truth, I have been too lazy to work this out.  I suppose it would involve opening more ports on the router firewall, as a first consideration.
Sorry I can't be of more help.
Regards,
Bob
