Chapter 8 Using Advanced Settings Firmware Restore Firmware restore lets the Router's firmware return to an earlier version, if the current version is unstable or does not meet specified needs. Click Firmware Restore from the Advanced screen to generate the "Firmware Restore" screen. The screen displays the "Active Firmware" and the "Backup Firmware." To restore the firmware to the backup firmware, click Restore Backup Firmware. A confirmation screen appears. Click OK to finish restoring the Router's firmware. Dynamic DNS Dynamic DNS (Domain Name Server) a dynamic IP address to be aliased to a static hostname, allowing a computer on the network to be more easily accessible from the Internet. Typically, when connecting to the Internet, the service provider assigns an unused IP address from a pool of IP addresses, and this address is used only for the duration of a specific connection. Dynamically assigning addresses extends the usable pool of available IP addresses, while maintaining a constant domain name. This allows to user to access a device (a camera, for example) from a remote location, since the device will always have the same IP address. When using Dynamic DNS, each time the IP address provided by the ISP changes, the DNS database changes accordingly to reflect the change. In this way, even though the IP address of the computer changes often, its domain name remains constant and accessible. 131

Using Advanced Settings
Firmware Restore
Firmware restore lets the Router’s firmware return to an earlier version, if the cur-
rent version is unstable or does not meet specified needs. Click
Firmware Restore
from the Advanced screen to generate the “Firmware Restore” screen.
The screen displays the “Active Firmware” and the “Backup Firmware.” To restore
the firmware to the backup firmware, click
Restore Backup Firmware
. A confir-
mation screen appears. Click
OK
to finish restoring the Router’s firmware.
Dynamic DNS
Dynamic
DNS
(Domain Name Server) a dynamic
IP
address to be aliased to a static
hostname, allowing a computer on the network to be more easily accessible from
the Internet. Typically, when connecting to the Internet, the service provider assigns
an unused
IP
address from a pool of
IP
addresses, and this address is used only for
the duration of a specific connection. Dynamically assigning addresses extends the
usable pool of available
IP
addresses, while maintaining a constant domain name.
This allows to user to access a device (a camera, for example) from a remote loca-
tion, since the device will always have the same
IP
address.
When using Dynamic
DNS
, each time the
IP
address provided by the
ISP
changes,
the
DNS
database changes accordingly to reflect the change. In this way, even
though the
IP
address of the computer changes often, its domain name remains
constant and accessible.
