M2M Cellular Gateway
service provider, the host name of the gateway, and the user name (or E‐mail address) and password
(or key) for authenticating to the service provider successfully. This device supports most popular third‐
party DDNS service provider, including DynDNS.org(Dynamic), DynDNS.org(Custom), No‐IP.com,
TZO.com, and DHS.org. Before you enable Dynamic DNS, you need to register an account with one of
these Dynamic DNS servers that we list in Provider field.
Once the IP address of a WAN interface in the gateway has changed, the dynamic DNS agent in the
gateway will inform the DDNS server with the new IP address. The server automatically re‐maps your
domain name with the changed IP address. So, other hosts in the Internet world will be able to link to
your gateway by using your domain name regardless of the changing global IP adress.
Dynamic DNS Scenario
Scenario Application Timing
When the IP address of the Gateway is often changed by ISP, and other hosts in the
Internet want to link to the gateway device by using its corresponding domain name.
The gateway must provide the dynamic DNS function to carry out the requirement.
Scenario Description
Apply one account to the DDNS provider for DDNS service before DDNS function in the
gateway can work.
The gateway asks the DDNS server to re‐map the domain name and WAN's IP address of
the gateway once the IP address has been changed.
Parameter Setup Example
Following table lists the parameter configuration as an example for the gateway in
above diagram with "Dynamic DNS" enabling.
Index skipping is used to reserve slots for new function insertion, when required.
