179 Chapter 22 Filter Configuration
Figure 117 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 Prestige applies data filters only. Packets are processed depending
on whether a match is found. The following sections describe how to configure filter sets.
22.1.1 The Filter Structure of the Prestige
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.
