MSN Messenger communicates using UPNP to try to auto-detect any UPNP-compliant firewalls/routers you may have. Ostensibly, NAT/Firewall devices that support UPNP will allow file transfers, voice and audio communications so MSN Messenger polls for them to autoconfigure itself and the NAT/Firewall device to support these transfer types.
So MSN Messenger thinks that a properly configured firewall would configure itself to let arbitrary connections to the outside world through just because a UPnP device asked it to? Gaak. Trying to get my mind around that concept is making my brain hurt. -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
