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.
• Wildcard: This function enables sub-domain name support. Enable this function when
there is any subdomain name.
• 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, the router will perform an update when your dynamic IP
address changes.
