5. After finishing the installation, go to My Network Places. You will find an icon (ex: Residential
Gateway Device) for the UPnP function.
6. Double-click the icon. The Gateway will open another Web page for UPnP functions. Now, the NAT
traversal function of UPnP will be available. The Gateway will create virtual servers automatically
when it detects the computer running some Internet applications that require this configuration.
Consult your Windows operating system documentation for more information on UPnP, installation, and
usage.
Security
Your gateway provides broad security measures against unwanted users. Security also allows for the
configuration of the gateway firewall, administrator password, (NAT) Network Address Translation, and
DMZ (Demilitarized Zone) configuration. A firewall is a system designed to prevent unauthorized access
to or from a private network. The administrator password allows you to configure all of the gateway
options. NAT is an Internet standard that enables a local-area network (LAN) to use one set of IP
addresses for internal traffic and a second set of addresses for external traffic. The hiding of internal
addresses allows greater security for your network. DMZ allows a device on your gateway through your
firewall. This feature is primarily used for gaming. The administrator logon allows you access to all of
the security options while the gamer user allows access to the firewall options and address translation.
The user logon does not allow you access to any of the security options.
To access security options,
1. Logon as the administrator.
2. Click Gateway in the toolbar.
3. Click Security in the left-navigation pane.
4. Please see the next section in this document titled Firewall.
