Always On: This setting provides convenience, but it leaves your network permanently
connected to the Internet.
On-Demand: Furnishes almost all the benefits of an Always On connection, but has
additional security benefits:
Your network cannot be attacked when it is not connected.
Your network may change address with each connection, making it more difficult to
attack.
Manual: This setting disables automatic connection attempts. The user must bring the
connection up and down via the Connect/Disconnect buttons.
• User Inactivity Timeout: For On-Demand connections only, you can specify the time in
seconds before disconnection if there is no data passing to or from the Internet.
UPnP: Universal Plug and Play (UPnP™) is a set of protocols that allows a PC to auto-
•
matically discover other UPnP devices (anything from an internet gateway device to a
light switch), retrieve an XML description of the device and its services, control the
device, and subscribe to real-time event notification. By default, UPnP is enabled on the
Motorola Netopia® Gateway.
For Windows XP users, the automatic discovery feature places an icon representing the
Motorola Netopia® Gateway automatically in the "My Network Places" folder. Double-
clicking this icon opens the Gateway's web UI.
PCs using UPnP can retrieve the Gateway's WAN IP address, and automatically create
NAT port maps. This means that applications that support UPnP, and are used with a
UPnP-enabled Motorola Netopia® Gateway, will not need application layer gateway sup-
port on the Motorola Netopia® Gateway to work through NAT.
You can disable UPnP, if you are not using any UPnP devices or applications. Uncheck
the UPnP Enabled checkbox.
When all of your entries are made, click the
Save and Restart Connection
button.
