    This is probably very easy, but I'm stupid about things like this, so...

    I have set up a static IP through DynDNS.com to point to my computer's dynamic
    IP. Now I am trying to figure out how to allow outside access to port 8080 so I can broadcast a webcam to my family at home. My internet connection is routed to me through two seperate routers- a Comcast cable modem, model number WCG200, recieves the signal, which then runs to my Vonage router, model number RT31P2. I guess I need to forward port 8080 on boh of my routers? This is all very confusing to me, and I've never gotten the whole port forwarding thing quite correct. Could someone please give me some advice on how to do this? Or at least point me in the right direction?

    Thanks very much in advance.

    Hmmm, I am not familar with cable modems, but can you configure it? Is there an administration page?

    Here in germany we have DSL and DSL-modems. Usually the modem is a dump device that does nothing but dial-in - no routing and masquerading stuff.

    Thus you should only have to forward port 8080 on your RT31P2 to the IP of your webcam.
