Netgear DGN100Bv3 Benutzerhandbuch

By default, this check box is selected. You can disable UPnP for automatic device 
configuration. If you clear the Turn UPnP On check box, the modem router does not allow 
any device to automatically control the resources, such as port forwarding (mapping), of 
the modem router. 

Type the advertisement period in minutes.

The advertisement period specifies how often the modem 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.

Type the advertisement time to live in hops.

The time to live for the advertisement is measured in hops (steps) for each UPnP packet 
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 4 hops, which 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.

Click the Apply button.

The UPnP Portmap Table displays the IP address of each UPnP device that is accessing 
the modem router and which internal and external port 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.

(Optional) To refresh the information in the UPnP Portmap Table, click the Refresh button.
