Microsoft released a long article extolling the virtues of UPnP where it pitches the system as a replacement for X.10 home automation, (e.g. everything including your alarm clock is UPnP enabled, and gets synchronised / alarms set by a central server), with only a small mention of the hideous firewall 'features' UPnP moves policy and security decisions from the firewall ruleset where they properly belong to a userspace app running on Windows - forgive me, but the designer of this system seems like a candidate for the Darwin Awards of the most dangerous and stupid network idea ever - just think the next version of Sasser / Fizzer would open ports on your $50 UPnP-enabled firewall and make you be an even bigger zombie host. And all in the name of 'ease of use' - bah. Let's hope a huge lawsuit against Netgear / Belkin / other low-end router manufr. puts an end to this disease. gdh How about a third. Permitting Microsoft's UPnP through you firewall is equivalent to taking all the curtains down in your house and letting the entire world look inside. But alas, they may not be content with just viewing as they may see some things they might like and will eventually break in at night and take them.
