ORT ILTERING
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 3G Mobile Wireless 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.
