Filter Configuration

8-3

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.

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.

To configure a filter set, follow the procedures indicated:

Step 1.  Type 21 in the main menu to open Menu 21.

Step 2.  Type the filter set to configure (no. 1 to 12) and press [ENTER]

.

Step 3.  Type a descriptive name or comment in the Edit Comments field and press [ENTER].
