B-6
Firewall
Security system designed to prevent unauthorized access to a private or
local network.
Anytime you connect a private network to the Internet, you run the risk of
exposing confidential data and systems to malicious attacks from the
outside world. A firewall acts as a security filter that protects your personal
computers and corporate networks from intentional hostile intrusion. A
firewall examines the traffic routed between your private and public network
to determine if it meets certain criteria. If the traffic is legitimate, it is allowed
to pass along, otherwise it is stopped.
The BG-2000 supports IP and packet filtering firewall functions.

hexadecimal range.
