Wireless-N 150 ADSL2+ Modem Router DGN1000 User Manual
1. Select UPnP on the main menu to display the UPnP screen:
Figure 5-10
2. Fill in the settings on the UPnP screen:
• Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. The
default setting for UPnP is enabled. If UPnp is disabled, the wireless modem router does
not allow any device to automatically control the resources, such as port forwarding
(mapping), of the wireless modem router.
• Advertisement Period. The advertisement period is how often the wireless modem router
advertises (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
might 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. A hop is the number of steps 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, then it might be necessary to increase this value a little.
• UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP
device that is currently accessing the wireless modem router and which ports (internal and
external) that device has opened. The UPnP Portmap Table also displays what type of port
is opened and if that port is still active for each IP address.
