11.2Configuring IP Filters

When you define an IP filter rule and enable the feature, you instruct the HM210dp/di 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 either be accepted (forwarded towards its destination) or denied (discarded) depending on the action specified in the rule.
