I'm trying to help you, but you aren't answering my questions...
My computer/camera are on the same network...which is why my camera source link looks like this: 192.168.1.255/video.cgi
I also use DDSN (running an updater on my computer) so that I can access my computer remotely. Using port forwarding, I am also able to access the camera remotely without using iCam. I don't know why I'd ever need to, but I have the ability to. If you answer the questions, I might be able to actually help you.
