UPnP limited number of ports?

    I'm making an experiment where I would try to use UPnP to forward the ports ports that are needed for MS Combat Flight Simulator 2, instead of forwarding them the oldfashioned way.

    I found an utility, UPnP Port Works, that can make the forwards from a cmd line, but it seems that I can only forward 25 ports in the router this way.

    Does any of you know if the number of forwarded ports in Tomato are limited to 25, and if there is a way to increase this number? About 200 - 250 ports are needs to be forwarded to make the game work on-line.

    The reason for the experiment is that some people have problems getting access to forward all the needed ports in their routers, but as far as I know their routers have UPnP, and I thought that could be a way to get around it. A simple .bat file to add all the needed ports, and another to remove them after the game.

    CFS2 is an old game, that doesn't seem to be designed for modern times where most people have a router between Internet and their computers.

    Never mind that question.
    I found out that Tomato's UPnP seems to handle the portforwarding for that game, without having to do anything manually.

    Hopefully that's the same for other routers with UPnP too, so people just need NOT to try manual port forwarding.
