Super G Wireless Router WGT624 v4 User Manual
Advanced Configuration 5-21
v1.0, July 2008
• 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 broadcast its
UPnP information. This value can range from 1 to 1440 minutes. The default period is 30
minutes. Shorter durations will 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. 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 you might need 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.
