Chapter 9 Filter Configuration
Figure 9-1. Outgoing Packet Filtering Process
For incoming packets, your Prestige applies data filters only. Packets are processed depending
upon whether a match is made. Your Prestige allows you to customize the filter sets that you wish
to use. The following sections describe how to configure filter sets.
The Filter Structure of the Prestige
You can configure up to twelve filter sets with six rules in each set, allowing you to customize up
to 72 filter rules (12 x 6).
When implementing these filter sets, you can link up to four of the filter sets together to screen
the data packet. Therefore, with each filter set having up to six rules, you can have a maximum of
24 rules active for a single filtering application.
