the Internet directly, the NAT function can be disabled.

Check one of the access methods among the 5 listed items and click

connection method.

The WAN-DNS is shown as below.

A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. In

the Internet, every host has a unique and friendly name such as www.yahoo.com

and an IP

address. As the IP Address is hard to remember, the DNS converts the friendly name into its

equivalent IP Address.

You can obtain a Domain Name System (DNS) IP address automatically if your ISP provides it

when you logon. Usually when you choose PPPoE or PPPoA as your WAN - ISP protocol, the

ISP will provide the DNS IP address automatically. You may leave it as blank. Or your ISP may

provide you with an IP address of their DNS. If this is the case, you must enter the DNS IP

address.
