ICA-500 User’s Manual

address.

HTTP Port 2:

The function is the same as http port 1. It’s the second choice of the port number.

Current implementation supports 2 HTTP port setting, the Http port 1 set to 80, the Http port 2 is not defined. The user can access the ICA-500 by

http://xx.xx.xx.xx/, or

http://xx.xx.xx.xx:xxxx/ to access the ICA-500.

Suggest keeping the Http port 1 as 80 to make sure the ICA-500 can be accessed by the default HTTP port setting access on the LAN. http://xx.xx.xx.xx/

If multiple ICA-500 is installed on the LAN, also required to be accessed from the WAN, then the Http port 2 can be changed as the virtual server port mapping to support multiple ICA-500.

Note: If you just want to reboot system without change anything. You could click SAVE button directly, then system will reboot again without any setting changed.

DDNS:

DDNS: Stands for Dynamic Domain Name Server

The ICA-500 supports DDNS. DDNS allows the ICA-500 to use an easier way to remember naming format rather than an IP address. The name of the domain is like the name of a person, and the IP address is like his phone number. On the Internet we have IP numbers for each host (computer, server, router, and so on), and we replace these IP numbers to easy remember names, which are organized into the domain name. As to ADSL environment, most of the users will use dynamic IP addresses. If users want to set up a web or a FTP server, then the Dynamic Domain Name Server is necessary. For more DDNS configuration, please consult your local dealer.

Your Internet Service Provider (ISP) provides you at least one IP address, which you use to connect to the Internet. The address you get may be static, meaning it never changes, or dynamic, meaning it’s likely to change periodically. Just how often it changes, depends on your ISP. A dynamic IP address complicates remote access since you may not know what your current WAN IP address is when you want to access your network over the Internet. The solution to the dynamic IP address problem comes in the form of a dynamic DNS service.

The Internet uses DNS servers to lookup domain names and translates them into IP addresses. Domain names, such as www.veo.com, are just easy to remember aliases for IP addresses. A dynamic DNS service is unique because it provides a means of updating your IP address so that your listing will remain current when your IP address changes. There are several excellent DDNS services available on the Internet and best of all they’re free to use. Two such services you can use are www.no-ip.com and www.DynDNS.org. You’ll need to register with the service and set up the domain name
