Backup / Restore
These functions allow you to save and backup your router’s current settings to a file on your
PC, or to restore a previously saved backup. This is useful if you wish to experiment with
different settings, knowing that you have a backup handy in the case of any mistakes. It is
advisable to backup your router’s settings before making any significant changes to your
router’s configuration.
Press
Backup
to select where on your local PC to save the settings file. You may also
change the name of the file when saving if you wish to keep multiple backups.
Press

to select a file from your PC to restore. You should only restore settings files
that have been generated by the Backup function, and that were created when using the
current version
of the router’s firmware.
Settings files saved to your PC should not be
manually edited in any way.
After selecting the settings file you wish to use, pressing

new users who are able to access the
device’s configuration interface. Once you have clicked on

options:
You can change the user’s
password
, whether their account is active and

Firewall and Access Control
Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet
access from your LAN, as well as helping to prevent attacks from hackers. In addition to this,
when using NAT (Network Address Translation. Please see the
WAN
configuration section for
more details on NAT) the router acts as a “natural” Internet firewall, as all PCs on your LAN will
use private IP addresses that cannot be directly accessed from the Internet.
Firewall
: Prevents access from outside your network. The router provides three levels of
security support:
NAT natural firewall
: This masks LAN users’ IP addresses which are invisible to outside users
on the Internet, making it much more difficult for a hacker to target a machine on your network.
This natural firewall is on when NAT function is enabled.
Firewall Security and Policy (General Settings)
: Inbound direction of Packet Filter rules to
prevent unauthorized computers or applications accessing your local network from the Internet.
Intrusion Detection

Access Control
: Prevents access from PCs on your local network:
Firewall Security and Policy (General Settings)
: Outbound direction of Packet Filter rules to
prevent unauthorized computers or applications accessing the Internet.
