• Advertisement Period. The advertisement period is 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 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 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 four hops. The default value is 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.
• 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 open and whether that port is still active for each IP address.
