Advertisement time to live. The time to live for the advertisement, measured in hops 

(steps) for each UPnP packet that is sent. Hops are the steps a packet takes between 
routers. The number of hops can range from 1 to 255. The default value for the 
advertisement time to live is four hops, which should be fine for most home networks. 
If you notice that some devices are not being updated or reached correctly, you might 
need to increase this value slightly.



In the main menu, under Advanced, select UPnP. 

Select the Turn UPnP On check box. 

By default, this check box is cleared. This 
prevents the gateway from allowing any 
device to automatically control the 
resources, such as port forwarding, of 
the gateway.

Complete the Advertisement Period and 

Advertisement Time to Live fields.

The UPnP Portmap Table displays the IP 
address of each UPnP device that is 
accessing the gateway and which 
internal and external ports of the 
gateway that device opened. The UPnP Portmap Table also displays the protocol for the 
port that was opened and if that port is still active for each IP address.

Perform one of the following actions:

Click Refresh to update the UPnP Portmap Table and to show the active ports that 
are currently opened by UPnP devices.
