Universal Plug and Play

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.
If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time
communications such as instant messaging or remote assistance (a feature in Windows XP),
you should enable UPnP.
To turn on Universal Plug and Play:

1. Select ADVANCED > Advanced Setup > UPnP.
2. Select the Turn UPnP On check box.
By default, this check box is selected. UPnP for automatic device configuration can be
enabled or disabled. If the Turn UPnP On check box is cleared, the modem router does
not allow any device to automatically control the resources, such as port forwarding
(mapping), of the modem router.
3. Type the advertisement period in minutes.
The advertisement period specifies how often the modem 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 can compromise the freshness of
the device status, but can significantly reduce network traffic.
4. Type the advertisement time to live in hops.
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 networks. If you notice that some devices are not being
updated or reached correctly, it might be necessary to increase this value.
5. Click the Apply button.
The UPnP Portmap Table displays the IP address of each UPnP device that is accessing
the modem router. The UPnP Portmap Table also shows which ports are open, what type
of ports are open, and whether each open port is still active for each IP address.
To refresh the information in the UPnP Portmap Table, click the Refresh button.
