RangeMax Wireless-N DSL Gigabit Modem Router DGN3500 User Manual 1. Select UPnP on the main menu to display the UPnP screen: Figure 5-8 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 modem router does not allow any device to automatically control the resources, such as port forwarding (mapping), of the modem router. • Advertisement 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. • 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 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. 5-16 v1.0, November 2009 Advanced Configuration
