HTTP Port:
The device supports two HTTP ports. The first one is default port 80 and this port is fixed.
This port is very useful for Intranet usage. The second HTTP port is changeable. Users
could assign the second port number of http protocol, and the WAN users should follow the
port number to login. If the http port is not assigned as 80, users have to add the port
number in back of IP address. For example:
http://192.168.1.100:8080 .
Therefore, the user can access the device by either
http://xx.xx.xx.xx/ , or
http://xx.xx.xx.xx:xxxx/ to access the device.
If multiple devices are installed on the LAN and also required to be accessed from the WAN,
then the HTTP Port can be assigned as the virtual server port mapping to support multiple
devices.

DDNS service
DDNS: Stands for Dynamic Domain Name Server
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 device over the Internet.
One of the possible solutions to the dynamic IP address problem comes in the form of a
dynamic DNS service.
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. One such service you can use is
www.DynDNS.org. You’ll need to register with the service and set up the domain name of
your choice to begin using it. Please refer to the home page of the service for detailed
instructions or refer to Appendix G for more information.
If your device is connected to xDSL directly, you might need this feature. However, if your
device is behind a NAT router, you will not need to enable this feature because your NAT
router should take care of this job. As to xDSL 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.
