ZyXEL Communications 792H manual Filter Set Configuration, Filter Structure of the Prestige

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.
