any device to automatically control the resources, such as port forwarding (mapping) of
the router.
3. Type the advertisement period in minutes.
The advertisement period specifies 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 traf
fic. Longer durations can compromise the freshness of the device
status, but can significantly reduce network traffic.
4. T
ype 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 router 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.
6. (Optional) T
o refresh the information in the UPnP Portmap Table, click the Refresh button.
