Configuring IP Filters
The IP filter feature enables you to create rules that control the
forwarding of incoming and outgoing data between your LAN and
the Internet. This chapter explains how to create IP filter rules.
Overview
The IP filter feature enables you to control the types of data being
passed between the Internet and your network. You can create IP
filter rules to block attempts by certain computers on your LAN to
access certain types of data or Internet locations. You can also
block incoming access to computers on your LAN.
When you define an IP filter rule and enable the feature, you instruct
HSA300 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 is carrying,
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 be either accepted (forwarded towards its destination), or
denied (discarded), depending on the action specified in the rule.
