DG834G v5 with FQDN to FVL328
This section is a case study on how to configure a VPN tunnel from a NETGEAR DG834G v5 to a
FVL328 using a fully qualified domain name (FQDN) to resolve the public address of one or both
routers. This case study follows the VPN Consortium interoperability profile guidelines (found at
).
Configuration Profile
The configuration in this section follows the addressing and configuration mechanics defined by
the VPN Consortium. Gather all the necessary information before you begin the configuration
process. Verify that the firmware is up to date, and that you have all the addresses that will be
necessary, and all of the parameters that need to be set on both sides. Check that there are no
firewall restrictions.

Using a Fully Qualified Domain Name (FQDN)
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 third-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. 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 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 uses the DDNS service provider when establishing a VPN tunnel.
To establish VPN connectivity, Gateway A must be configured to use Dynamic DNS, and
Gateway B must 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
1.
Log in to the DG834G v5 labeled Gateway A as in the illustration.
Out of the box, the DG834G v5 is set for its default LAN address of http://192.168.0.1 with its
default user name of
admin
, and default password of
password
. 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.
2.
On the DG834G v5, configure the Dynamic DNS settings.
