Figure 11 DDNS setup
This page is used to configure DDNS. Dynamic DNS (DDNS) allows a dynamic IP
address to be aliased to a static, pre-defined host name so that the host can be
easily contacted by other hosts on the internet even if its IP address changes.
The CMRG supports a dynamic DNS client compatible with the Dynamic DNS
service (
http://www.dyndns.com/
).
To activate the DDNS client:
1. Go to the DynDNS website and create an account for the Dynamic DNS service.
You will create a username and password, and be asked to choose a host name for
your server, and the dynamic DNS domain to which your host will be assigned.
You will also be asked for your host’s current IP address. This is the WAN IP
address that has been assigned to your CMRG during provisioning. (See WAN IP
Address on the Basic / Setup web page.)
2. Enter your account information on the Basic / DDNS web page, enable the
service by selecting www.DynDNS.org from the DDNS Service drop-down list, and
click Apply.
3. The DDNS client will notify the DDNS service whenever the WAN IP address
changes so that your chosen host name will be resolved properly by inquiring hosts.
The current status of the service is shown at the bottom of the DDNS web page.
