Figure 227 Filter Rule Process

You can apply up to four filter sets to a particular port to block various types of packets.

Because each filter set can have up to six rules, you can have a maximum of 24 rules active for

a single port.

For incoming packets, your ZyXEL Device 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 ZyXEL Device

A filter set consists of one or more filter rules. Usually, you would group related rules, for

example, 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.
