Set Networking Protocols - NETGEAR CG4500BDv2 User Manual

• Advertisement time to live. The time to live for the advertisement, measured in hops
(steps) for each UPnP packet that is sent. Hops are the steps a packet takes between
routers. The number of hops can range from 1 to 255. The default value for the
advertisement time to live is four hops, which should be fine for most home networks.
If you notice that some devices are not being updated or reached correctly, you might
need to increase this value slightly.

To configure UPnP:
1. In the main menu, under Advanced, select UPnP.
2. Select the Turn UPnP On check box.
By default, this check box is cleared. This
prevents the gateway from allowing any
device to automatically control the
resources, such as port forwarding, of
the gateway.
3. Complete the Advertisement Period and
Advertisement Time to Live fields.
The UPnP Portmap Table displays the IP
address of each UPnP device that is
accessing the gateway and which
internal and external ports of the gateway
that device opened. The UPnP Portmap Table also displays the protocol for the port that
was opened and if that port is still active for each IP address.
4. Perform one of the following actions:
• Click Apply to save your settings.
• Click Cancel to disregard any unsaved changes.
• Click Refresh to update the UPnP Portmap Table and to show the active ports that
are currently opened by UPnP devices.
