Using Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network.
Figure 8-14
From the main menu of the browser interface, under Advanced, click on UPnP. Set up UPnP according to the guidelines below.
Turn UPnP On—UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is disabled. If disabled, the router will not allow any device to automatically control the resources, such as port forwarding (mapping) of the router.
Note: If you use applications such as multi-player gaming, peer-to-peer connections, real 
time communications such as instant messaging, or remote assistance (a feature in
Windows XP), you should enable UPnP.
Advertisement Period—the Advertisement Period is how often the router will broadcast its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of additional network traffic. Longer durations may compromise the freshness of the device status but can significantly reduce network traffic.
