    On a XP system, public access AP, I am receiving floods of these
    incoming UDP packets. If I block port 1900, I lose my assigned IP and
    cannot reconnect. On another system windows 98SE, if I block port 1900,
    no problem, stay connected.

    Anyone know what the purpose of these incoming UDP packets is? They are
    being sent by the gateway/dns server..

    Port 1900 is uPNP, it shouldn't be required in most cases unless you're
    using uPNP, but I've seen weirder things.
