Step-By-Step Configuration - NETGEAR DG834GUv5 Reference Manual

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 email addresses, host names and IP addresses) can be stored and retrieved. Now, a
gateway can be configured to use a 3
address to establish bi-directional VPN connectivity.
To use DDNS, you must register with a DDNS service provider. Example 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 an example 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 will use the DDNS Service Provider when establishing a VPN
tunnel.
In order to establish VPN connectivity Gateway A must be configured to use Dynamic DNS, and
Gateway B must be configured to use a DNS hostname to find Gateway A provided by a DDNS
Service Provider. 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.
