Broadband/ADSN Connection without Static IP Address

Using Dynamic DNS
The Dynamic DNS is an application that allows user to register a domain name that always points to their GV-System. This application is only necessary when your GV-System is using a dynamic IP address. If so the DDNS will update GV-System’s IP address to DNS server in every 10 minutes. Therefore, even if your GV-System’s IP address changes, you can still locate it by using the registered domain name.
Dynamic DNS supports Windows XP, Windows 2000, and Windows Server 2003 only, it will not support Windows 95/98 or ME.

Dynamic DNS uses port: 80 to upload IP address over the Internet. If your GV-System is connected
behind a router or firewall, please make sure port: 80 are open. Dynamic DNS will only upload Global
IP addresses. If your GV-System is using virtual IP port mapping should be done first.

Installing Dynamic DNS
Insert System CD-ROM into GV-System’s CD-ROM drive. Open V6, then DDNS, Run SETUP.EXE. Select Register Dynamic IP then click Next. Select Dynamic DNS Service then click Next. Determine whether you want to auto run Dynamic DNS AP at Windows startup then click Next. Follow rest of the installation Wizard to complete.
