    Scroll down to the uPNP description
    http://www.draytek.co.uk/products/vigor2600.html

    Essentially, the Windows uPNP service is taking control of your DSL
    router and punching holes in the firewall configuration as it deems
    necessary. Personally I don't trust Windows that much and would
    manually configure it as needed. I'd probably also disable the uPNP
    support on the router.

    It just aint a good idea letting the clients arbitrarily reconfigure
    the firewall. That defeats the purpose of a seperate firewall dontcha
    think? Pretty soon, some spyware or virus is going to figure out how
    to use uPNP. There have already been a few security issues with the
    protocol.
