7.2.2 Configuring a Filter Rule
To configure a filter rule, type its number in
Menu 21.1 — Filter Rules Summary
and press [ENTER] to
open menu 21.1.1 for the rule.
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 filter field or vice versa, the Prestige will warn you and will not allow you to save.
7.2.3 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.
To configure TCP/IP rules, select press [
ENTER
] to open
Menu 21.1.1 — TCP/IP Filter Rule
, as shown
