Chapter 3 – Using the Web Management Software
IP Setup, DDNS Configuration Parameters
DDNS (Dynamic Domain Naming System) allows you to have a static domain name with a dynamic IP address.
When the dynamic IP address changes, it is submitted to the DDNS server. Here, the domain name is updated to point to the new IP address.
You must register with a DDNS server to use this feature.
General Group
This section describes the parameters that you can configure in the General group.
DDNS
Check the Enable or Disable box. This enables/disables DDNS. Default is Disable.
Use Check IP
Check the Enable or Disable box. If enabled, the program queries the server to determine the IP address before it performs the DDNS update (the IP address is still assigned by the wireless provider and the DDNS is updated based on the address returned by Check IP
Server). If disabled, the program performs the DDNS update using the IP address that it obtains from the PPP link. Default is Enable.
Check IP Server
Enter the Server name from which the currently assigned IP address is obtained. This server is a server the router accesses to check its current IP address.
Check IP Port

Enter the port number of the Check IP Server. Default is 80.
