    How to open a uPnP forwarded port

    Our software will be installed behind a ifrewall, but we need it to accept incoming connections on a specific port. I figure what I need to do is use port forwarding via uPnP. How do you do this in C/C++ for windows, using Visual Studio 6.0?

    Everythign I looked for on the net just wants to discuss the overall architecture fo port forarding, not how to do it in a program.

    You can't, unless you can tell the router what to do -- or you have a computer running as a gateway (and your program handles/forwards connections).

    Well gee, thats odd because uTorrent does it as well as several other software packages.

    The external links include protocol specifications and implementations.

    again, while that is interesting it does not actually give any meaningful examples. I already know what uPnP is, I need code that shows how to implement it in C/C++

    Oh but it does, down the bottom of the wiki page it links "Free ANSI C library to control a Universal Plug and Play Internet Gateway Device" @ http://miniupnp.free.fr/

    yes perhaps, but when i tried to DL it from that site I kept getting connect errors, so I figured the link was broken.
