Outgoing Packet Filtering Process

For incoming packets, your Prestige applies data filters only. Packets are processed depending upon whether a match is found. 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.
