UPnP Help
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.
Turn UPnP On
UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is
enabled. If disabled, the router will not allow any device to automatically control the resources,
such as port forwarding (mapping), of the router.
Advertisement Period
The Advertisement Period is how often the router will advertise (broadcast) its UPnP information.
This value can range from 1 to 1440 minutes. The default period is for 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
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 may 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 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.
