retrieved. Now, a gateway can be configured to use a third-party service instead of a 
permanent and unchanging IP address to establish bi-directional VPN connectivity.

To use DDNS, you need to register with a DDNS service provider. Some DDNS service 
providers include:

DynDNS: www.dyndns.org

TZO.com: netgear.tzo.com

ngDDNS: ngddns.iego.net

In this example, Gateway A is configured using a sample FQDN provided by a DDNS service 
provider. In this case we established the hostname dg834g.dyndns.org for Gateway A using 
the DynDNS service. Gateway B uses the DDNS service provider when establishing a VPN 
tunnel. 

To establish VPN connectivity, Gateway A has to be configured to use Dynamic DNS, and 
Gateway B has to be configured to use a DNS host name provided by a DDNS service 
provider to find Gateway A. Again, the following step-by-step procedures assume that you 
have already registered with a DDNS service provider and have the configuration information 
necessary to set up the gateways.

Step-by-Step Configuration

Log in to Gateway A (your modem router).

This example assumes that you have set the local LAN address as 10.5.6.1 for Gateway 

A and have set your own password.

On Gateway A, configure the Dynamic DNS settings.

On the Advanced tab, select Advanced Setup > Dynamic DNS to display the 

following screen:

Fill in the fields with account and host name settings.

Select the Use a Dynamic DNS Service check box.

In the Host Name field, type gw_a.dyndns.org.

In the User Name field, enter the account user name.

In the Password field, enter the account password.

Click Apply.
