2. Specify the following settings:
• Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration.
The default setting for UPnP is enabled. If this check box is not selected, the gateway
does not allow any device to control the resources automatically, such as port
forwarding (mapping) of the gateway.
• Advertisement Period. The advertisement period is how often the gateway
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 more network traffic. Longer durations can
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 number of hops can range from 1 to
255. The default value for the advertisement time to live is four hops, which is fine for
most home networks. If you notice that some devices are not being updated or
reached correctly, you should increase this value.
3. Click the Apply button.
Your settings are saved.
The UPnP Portmap Table displays the IP address of each UPnP device that is accessing the
gateway and which ports (internal and external) that device has opened. The UPnP Portmap
Table also displays what type of port is open and whether that port is still active for each IP
address.
