32.2.1 Configuring a Filter Rule

To configure a filter rule, type its number in Menu 21.1.1 - Filter Rules
Summary and press [ENTER] to open menu 21.1.1.1 for the rule.
To speed up filtering, all rules in a filter set must be of the same class, that is,
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 filter field or vice versa, the P-793H v2 will warn you and will not allow
you to save.

32.2.2 Configuring a TCP/IP Filter Rule

This section shows you how to configure a TCP/IP filter rule. TCP/IP rules allow
you to base the rule on the fields in the IP and the upper layer protocol, for
example, UDP and TCP headers.
