Universal Plug and Play

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, 
to 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.

If you use applications such as multiplayer gaming, peer-to-peer 

connections, real-time communications such as instant messaging, 
or remote assistance (a feature in Windows XP), you should enable 
UPnP.

Select 

Advanced > UPnP. The UPnP screen displays.

The available settings and information displayed in this screen are:

Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. 

The default setting for UPnP is disabled. If this check box is not selected, the router 
does not allow any device to automatically control the resources, such as port 
forwarding (mapping) of the router.

Advertisement Period. The advertisement period is how often the router broadcasts 

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 might compromise the 
freshness of the device status but can significantly reduce network traffic.

Advertisement Time To Live. The time to live for the advertisement is measured in 

hops (steps) for each UPnP packet sent. The time to live hop count is the number of 
steps a broadcast packet is allowed to propagate for each UPnP advertisement 
before it disappears. The number of hops can range from 1 to 255. The default value 
for the advertisement time to live is 4 hops, which should be fine for most home
