30.2.1 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, 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 ZyXEL
Device will warn you and will not allow you to save.

30.2.2 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.
To configure TCP/IP rules, select TCP/IP Filter Rule from the Filter Type field and press
[ENTER] to open Menu 21.1.1.1 - TCP/IP Filter Rule, as shown next
