NETGEAR VPN Configuration FVS318 or FVM318 with FQDN to FVS328

Many ISPs (Internet Service Providers) provide connectivity to their customers using dynamic 
instead of static IP addressing. This means that a user’s IP address does not remain constant over 
time, which presents a challenge for gateways attempting to establish VPN connectivity.

A Dynamic DNS (DDNS) service allows a user whose public IP address is dynamically assigned 
to be located by a host or domain name. It provides a central public database where information 
(such as e-mail addresses, host names and IP addresses) can be stored and retrieved. Now, a 
gateway can be configured to use a 3

rd

 party service in lieu of a permanent and unchanging IP 

address to establish bi-directional VPN connectivity.

To use DDNS, you must register with a DDNS service provider. Example DDNS Service 
Providers include:

In this example, Gateway A is configured using an example FQDN provided by a DDNS Service 
provider. In this case we established the hostname netgear.dyndns.org for Gateway A using the
