7-14 Advanced Configuration of the Router
202-10039-01
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 will 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.
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 networks. If you notice that some devices are not being updated or reached
correctly, then it may be necessary to increase this value a little.
UPnP Portmap Table: The UPnP Portmap Table displays the IP address of each UPnP device that
is currently accessing the router and which ports (Internal and External) that device has opened.
The UPnP Portmap Table also displays what type of port is opened and if that port is still active for
each IP address.
