30/83
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://192.168.0.100:8080
.
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 H 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.
