ICA-500 User’s Manual
26/80
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
