N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000
To turn on Universal Plug and Play:
1. Select ADVANCED > Advanced Setup > UPnP.
2.The available settings and information in this screen are:
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 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 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 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 open and whether that port is still active for each IP address.
