4.3.3.4 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
Browse
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

4.3.4 Firewall
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) the router acts as a “natural” Internet
firewall, since all PCs on your LAN use private IP addresses that cannot be directly
accessed from the Internet. See the
WAN
configuration section for more details on NAT.
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 the NAT function is enabled.
When using Virtual Servers (port forwarding) your PCs are exposed to the
degree specified in your Virtual Server settings provided the ports specified
are opened in your firewall packet filter settings.

prevent unauthorized computers or applications accessing your local network from the

attacks.
MAC Filter rules
: Prevents unauthorized computers accessing the Internet.
URL Filter
: Blocks PCs on your local network from unwanted websites.
A detailed explanation of each of the following five items appears in the
