The UPnP facility on the router enables UPnP aware applications such as MSN Messenger to
discover what are behind a NAT router. The application will also learn the external IP
address and configure port mappings on the router. Subsequently, such a facility forwards
packets from the external ports of the router to the internal ports used by the application.
The reminder as regards concern about Firewall and UPnP
Can't work with Firewall Software
Enabling firewall applications on your PC may cause the UPnP function not working
properly. This is because these applications will block the accessing ability of some
network ports.
Security Considerations
Activating the UPnP function on your network may incur some security threats. You
should consider carefully these risks before activating the UPnP function.
¾ Some Microsoft operating systems have found out the UPnP weaknesses and hence
you need to ensure that you have applied the latest service packs and patches.
¾ Non-privileged users can control some router functions, including removing and
adding port mappings.
The UPnP function dynamically adds port mappings on behalf of some UPnP-aware
applications. When the applications terminate abnormally, these mappings may not be
removed.
