Using a Dynamic DNS Service

54 Mbps Wireless Router WGR614v7 Reference Manual

Using a Dynamic DNS Service

If your network has a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you will not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial dynamic DNS service, who will allow you to register your domain to their IP address, and will forward traffic directed at your domain to your frequently-changing IP address.

Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the dynamic DNS service will not work because private addresses will not be routed on the Internet.

The router contains a client that can connect to many popular dynamic DNS services. You can select one of these services and obtain an account with them. Then, whenever your ISP-assigned IP address changes, your router will automatically contact your dynamic DNS service provider, log in to your account, and register your new IP address.

From the Main Menu of the browser interface, under Advanced, click on Dynamic DNS.

To configure Dynamic DNS:

1.Register for an account with one of the dynamic DNS service providers whose names appear in the ‘Select Service Provider’ box. For example, for dyndns.org, go to www.dyndns.org.

Each LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a normal connection e.g. connecting to a computer or an uplink connection e.g. connecting to a router, switch, or hub. That port will then configure itself to the correct configuration. This feature also eliminates the need to worry about crossover cables, as Auto UplinkTM will accommodate either type of cable to make the right connection B-16 54 Mbps Wireless Router WGR614v7 Reference ManualNetwork, Routing, Firewall, and Basics AprilAppendix C Preparing Your Network Computer Network Configuration RequirementsWhat You Need To Use a Router with a Broadband Modem Cabling and Computer HardwareWhere Do I Get the Internet Configuration Parameters?

How Does WPA Compare to WPA2 IEEE 802.11i? What are the Key Features of WPA and WPA2 Security?The primary information conveyed in the Beacon frames is the authentication method and the cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared key is an authentication method that uses a statically configured pass phrase on both the stations and the access point. This obviates the need for an authentication server, which in many home and small office environments will not be available nor desirable. Possible cipher suites include WEP, TKIP, and AES Advanced Encryption Standard.
