Reference Manual for the ADSL Modem Wireless Router DG834GSP
7-14 Advanced Configuration
v1.0, June 2007
1. Click UPnP on the main menu to invoke the UPnP menu:
2. Fill out the UPnP screen:
• Turn UPnP On: UPnP can be enabled or disabled for automatic device configuration. The
default setting for UPnP is enabled. If disabled, the Router will not allow any device to
automatically control the resources, such as port forwarding (mapping), of the Router.
• Advertisement Period: The Advertisement Period is how often the Router will advertise
(broadcast) its UPnP information. This value can range from 1 to 1440 minutes. The
default period is for 30 minutes. Shorter durations will ensure that control points have
current device status at the expense of additional network traffic. Longer durations may
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 may 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 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.
3. To save, cancel or refresh the table:
a. Click Apply to save the new settings to the Router.
b. Click Cancel to disregard any unsaved changes.
