8.3 Configuring a Filter Rule
To configure a filter rule, enter its number in Menu 21.1 - Filter Rules Summary and press [ENTER] to
open menu 21.1.1 for the rule.
There are three types of filter rules: TCP/IP, IPX and Generic. Depending on the type of rule, the
parameters below the type will be different. Use the [SPACE BAR] to select the type of rule that you wish
to create in the Filter Type field and press [ENTER] to open the respective menu.
To speed up filtering, all rules in a filter set must be of the same class, i.e., protocol filters or generic filters.
The class of a filter set is determined by the first rule that you create. When applying the filter sets to a
port, separate menu fields are provided for protocol and device filter sets. If you include a protocol filter set
in a device filters field or vice versa, the Prestige will warn you and will not allow you to save.
