Your router can secure your network and data communications with built-in
firewall capabilities. A firewall is any combination of hardware and software
that secures a network and traffic to prevent interception or intrusion. Your
router is equipped with predefined scripts that can be modified or used directly to
construct firewalls. You can select from four firewall options:
•Maximum: Establishes a firewall with the most restrictive policies
for maximum network security.
•Medium: Establishes a firewall with flexible policies for a moderat e
level of network security.
•Minimum: Establishes a firewall with a basic set of policies for a
minimum level of network security.
•None: No firewall.
Make your selection, and press the Apply button to implement your firewall. To
cancel, press the Back to Home button and return to the home screen.
For many networks, these predefined firewalls will protect against all but the
most sophisticated attacks. For the experienced network security technician,
these predefined scripts can serve as a starting point for custom configurations to
support your own unique network policies.
CAUTION:
All network security efforts, including firewall configurations, should be
performed by an experienced and qualified network security technician, who is
familiar with the unique architecture and requirements of your network.
Efficient Networks cannot be liable for security violations due to inadequate or
incorrect firewall configurations.
