8 FIREWALL CONFIGURATION
The Mini 3G Broadband Router provides extensive firewall protection by
restricting connection parameters to limit the risk of intrusion and
defending against a wide array of common hacker attacks.
Firewall Configuration contains the following sections:
“MAC/IP/Port Filtering” on page 96
“Virtual Server Settings (Port Forwarding)” on page 99
“DMZ” on page 101
“System Security” on page 102
“Content Filtering” on page 103
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 3G 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.
