Update DDNS automatically
Dynamic DNS (Domain Name Service) is a method of keeping a domain name linked to a changing (dynamic) IP address. With most Cable and DSL connections, you are assigned a dynamic IP address and that address is used only for the duration of that specific connection. To properly configure the DDNS feature follow the steps below:
Step 1 Log into the web based configuration by typing in the IP address of the router (default:192.168.0.1) in your web browser. The username is admin (all lowercase) and the password is blank (nothing).
Step 2 Click on the Tools tab and then click Misc. If you have the DI-614+ with firmware 2.30, click on Tools > Parental Control.
Step 3 Enter the required information under Dynamic DNS:
Server Address: Enter the IP Address or domain name of your DDNS server (IE members.dyndns.org).
Host Name: Enter the Domain name that you registered with your DDNS service provider, (IE mydomain.dyndns.org).
Step 4 Click Apply and then Continue to save your changes.
