N300 Wireless ADSL2+ Modem Router DGN2200v3
To set up UPnP:
1. Select Advanced > UPnP to display the following screen:
2. Specify the settings as follows:
Tu
rn UPnP On. UPnP can be enabled or disabled for automatic device configuration.
The default setting for UPnP is enabled. If UPnP is disabled, the modem router does
not allow any device to automatically control the resources, such as port forwarding
(mapping), of the modem router.
Advertisem
ent Period. The advertisement period is how often the 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.
Adv
ertisement Time to Live. This 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 is 4 hops, which works for most home networks. If you notice that some
devices are not being updated or reached correctly, you might need to increase this
value a little.
UPn
P Portmap Table. The UPnP Portmap Table displays the IP address of each
UPnP device that is currently accessing the 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.
3. T
o save, cancel your changes, or refresh the table:
Click Apply to save t
he new settings to the modem router.
Click Canc
el to disregard any unsaved changes.

resh to update the portmap table and to show the active ports that are
