VoIP/(802.11g) ADSL2+ VPN Firewall Router
Chapter 4: Configuration
Dynamic DNS
The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname,
allowing users whose ISP does not assign them a static IP address to use a domain name. This is
especially useful for hosting servers via your ADSL connection, so that anyone wishing to connect
to you may use your domain name, rather than having to use your dynamic IP address, which
changes from time to time. This dynamic IP address is the WAN IP address of the router, which is
assigned to you by your ISP.
You will first need to register and establish an account with the Dynamic DNS provider using their
website, for example http://www.dyndns.org/
There are more than 5 DDNS services supported.
Disable:
Check to disable the Dynamic DNS function.
Enable:
Check to enable the Dynamic DNS function. The following fields will be activated
and required:
Dynamic DNS Server:
Select the DDNS service you have established an account with.
Domain Name, Username and Password:
Enter your registered domain name and your
username and password for this service.
Period:
Set the time period between updates, for the Router to exchange information with the
DDNS server. In addition to updating periodically as per your settings, the router will perform an
update when your dynamic IP address changes.
Via WAN Interface:
Decide which WAN interface you want to use for sending DDNS request.
