Configuring Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access
the network and connect to other devices as needed. UPnP devices can automatically discover the
services from other registered UPnP devices on the network.
To configure UPnP:
1.
Log in to the gateway as described in “Logging in to the Gateway” on page 1-5 .
2.
In the main menu, under Advanced, select
UPnP
. The UPnP screen displays.
3.
Select the
Turn UPnP On
check box. The default setting is disabled, which prevents the
gateway from allowing any device to automatically control of its the resources, such as port
forwarding.
4.
Enter the following information:
•
Advertisement Period
. Enter how often the gateway broadcasts its UPnP information.
The default is 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
. Enter the time to live for the advertisement, which is
measured in hops (steps) from 1 to 255 for each UPnP packet that is sent. A hop is the
number of steps allowed to propagate for each UPnP advertisement before it disappears.
The default setting is 4 hops, which is fine for most home networks. If some devices are
not updated or reached correctly, you might need to increase this value slightly.
