It seems like a routing issue, but I can't answer what your ISP may be doing.

I've installed a Linksys WVC11B camera in my home via a wireless network, and it works just fine, as long as I'm at home viewing it through one of the two computers on the network.
However, when I type in my IP address, and the port number into IE, the page won't load up. I've checked my router, and I have port forwarding, with port 1024 enabled.
I spent 4 hours on the phone with Linksys, and then sent the camera back for a new one (they thought it might be a hardware problem). Needless to say, the second camera doesn't work any better.
Could this be a problem with my ISP (Mediacom Cable)? Is there a way they can block a request from being routed to my camera?
Any suggestions would be appreciated!
