When you define an IP filter rule and enable the feature, you instruct
the Hurricane 9200/S to examine each data packet it receives to
determine whether it meets criteria set forth in the rule. The criteria
can include the size of the packet, the network or internet protocol it
carries, the direction in which it is traveling (for example, from the
LAN to the Internet or vice versa), the IP address of the sending
computer, the destination IP address, and other characteristics of
the packet data.
If the packet matches the criteria established in a rule, the packet
can either be accepted (forwarded towards its destination), or
denied (discarded), depending on the action specified in the rule.
