Firmware Restore
Firmware restore resets the Router’s firmware 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 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.
