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 which will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to whatever your current IP address happens to be.
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.
2. Select the Use a Dynamic DNS service check box.
3. Select the name of your dynamic DNS Service Provider.
4. Type the Host Name (or domain name) that your dynamic DNS service provider gave you.
5. Type the User Name for your dynamic DNS account.
6. Type the Password (or key) for your dynamic DNS account.
7. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may
select the Use wildcards check box to activate this feature.
For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same
IP address as yourhost.dyndns.org
8. Click Apply to save your configuration.
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.
