Prestige 791R G.SHDSL Router

For incoming packets, your Prestige applies data filters only. Packets are processed depending on whether a match is found. The following sections describe how to configure filter sets.

The Filter Structure of the Prestige

A filter set consists of one or more filter rules. Usually, you would group related rules, e.g., all the rules for NetBIOS, into a single set and give it a descriptive name. You can configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the system.

You can apply up to 4 filter sets to a particular port to block multiple types of packets. Because each filter set can have up to 6 rules, you can have a maximum of 24 rules active for a single port.
