Customizing Your Network 5-11
v1.1, May 2009
Managing the URL to Connect to The Gateway
To manage the gateway via the Internet, you need its public IP address, as seen from the Internet.
This public IP address is allocated by your ISP, and is shown under “IP Address to connect this
device” in the Remote Management screen. Note that if your ISP account uses a dynamic IP
address instead of a fixed IP address, the address can change each time you connect to your ISP.
There are two solutions for this issue:
• Be sure that your ISP allocates a fixed IP address for the gateway.
• Use the Dynamic DNS feature so you can connect using a domain name, rather than an IP
address. See “Configuring Dynamic DNS” on page 5-1.
Configuring Universal Plug and Play (UPnP)
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.
To configure UPnP:
1. In the main menu, under Advanced, select UPnP. The UPnP screen displays.
2. Select the Turn UPnP On check box. The default setting is disabled, which prevents the
gateway from allowing any device to automatically control of its the resources, such as port
forwarding.
