2. In ATM mode, if only a single PVC with IPoA or static IPoE protocol is configured, Static DNS server IP addresses

must be entered.

3. If you cannot locate the static DNS server IP information, ask your ISP to provide it.

4. The default settings are recommended if you are unsure about the DNS server addresses. If a wrong DNS server

address is configured, webpages may not be open.

Dynamic DNS (DDNS)

If your Internet service provider (ISP) gave you a static (fixed) public IP address, you can register a domain name and

have that name associated with your IP address by public Domain Name Servers (DNS). However, if your ISP gave you

a dynamic (changing) public IP address, you cannot predict what your IP address will be, and the address can change

frequently. In this case, you can use a commercial Dynamic DNS service. It lets you register your domain to their IP

address and forwards traffic directed at your domain to your frequently changing IP address.If your ISP assigns a private

WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic DNS service does not work because private addresses

are not routed on the Internet.

4.2.10 DSL

This screen provides multiple ASDL modulation modes to meet diversified environments. You can also select phone line

pair and Capability.

DSL parameter configurations must be supported by ISP to take effect. Actual parameters (see Statistics-xDSL) resulted

from the negotiation between your router and ISP. Wrong configurations may fail your Internet access.

The best DSL configurations are the factory defaults. Only change them if you are instructed by your ISP or our

technical staff when your router fails to negotiate with ISP in DSL (ATM) mode.

Usually, this failure can be identified

and confirmed if the ADSL LED on the device keeps displaying a slow or quick blinking light.

Check the checkbox next to a modulation to enable it and then click

Apply/Save

.

UPnP

UPnP (Universal Plug and Play) allows Windows based systems to configure the device for various Internet applications

automatically. UPnP devices can automatically discover the services from other registered UPnP devices on the network.

If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications, such as

instant messaging or remote assistance (a feature in Windows XP), you should enable UPnP.

Enable UPnP:
