IP Setup > DDNS Configuration

DDNS (Dynamic Domain Naming System) updates the IP address of the modem/router in a DDNS server for the

configured domain name whenever the IP Address changes; thus, it leaves the domain name pointing to the current IP

Address of the modem/router at all times.

General

DDNS: Check the Enable or Disable box. This enables/disables DDNS.

Default = Disable.

Use Check IP: Check the Enable or Disable box. If enabled, the program will query 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 will be updated based on the

address returned by Check IP Server). If disabled, the program will perform the

DDNS update using the IP address that it obtains from the PPP link. Default =

Enable.

Check IP Server: Enter the Server name from which the currently assigned IP address is obtained.

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

Server: Enter the Server name to which the IP Address change is registered. Example:

members.dyndns.org

Port: Enter the Server port number. Default is 80.

Max Retries: Enter the maximum number of tries that will be allowed if the update fails.

Default = 5. Range is 0 – 100.

Update Interval: Enter the intervals in days that will be allowed to pass when there is no IP Address

change. At the end of this interval, the existing IP Address will be updated in the

server so that it will not expire. Default = 28 days. Range is 1 – 99 days.

System: Sets the system registration type as either Dynamic or Custom. Default = Dynamic.

Domain: Enter the registered Domain name.

Authentication

User Name: Enter the User Name that can access the DDNS Server. Default = NULL.

Password: Enter the Password that can access the DDNS Server. Default = NULL.

Submit

completed and submitted all the screens on which you have made changes.
