304 Chapter 30 Filter Configuration

Refer to the next section for information on configuring the filter rules.

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.
