restricting connection parameters to limit the risk of intrusion and
defending against a wide array of common hacker attacks.

◆ “MAC/IP/Port Filtering” on page 100
◆ “Virtual Server Settings (Port Forwarding)” on page 103
◆ “DMZ” on page 104
◆ “System Security” on page 105
◆ “Content Filtering” on page 106
MAC/IP/PORT FILTERING
MAC/IP/Port filtering restricts connection parameters to limit the risk of
intrusion and defends against a wide array of common hacker attacks.
MAC/IP/Port filtering allows the unit to permit, deny or proxy traffic
through its MAC addresses, IP addresses and ports.
The Mini Broadband Router allows you define a sequential list of permit or
deny filtering rules (up to 32). This device tests ingress packets against the
filter rules one by one. A packet will be accepted as soon as it matches a
permit rule, or dropped as soon as it matches a deny rule. If no rules
match, the packet is either accepted or dropped depending on the default
policy setting.
