D6300 WiFi DSL Modem Router
Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration.
The default setting for UPnP is disabled. If this check box is not selected, the WiFi
modem router does not allow any device to automatically control the resources, such as
port forwarding (mapping) of the WiFi modem router.
Advertisement Period. The advertisement period is how often the WiFi 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.
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 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.
UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP
device that is currently accessing the WiFi modem 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.
