Chapter 36 Filter Configuration

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.x.1 – TCP/IP Filter Rule, as shown next.

Figure 211   Menu 21.1.x.1 TCP/IP Filter Rule

The following table describes how to configure your TCP/IP filter rule.

Table 127   Menu 21.1.x.1 TCP/IP Filter Rule

Filter #

This is the filter set, filter rule coordinates, for instance, 2, 3 refers to the second filter 
set and the third filter rule of that set.

Filter Type

Use [SPACE BAR] and then [ENTER] to choose a rule. Parameters displayed for 
each type will be different. Choices are TCP/IP Filter Rule or Generic Filter Rule.

Active

Select Yes to activate or No to deactivate the filter rule.

IP Protocol

This is the upper layer protocol, for example, TCP is 6, UDP is 17 and ICMP is 1. 
The value must be between 0 and 255. A value of 0 matches ANY protocol.

IP Source Route

IP Source Route is an optional header that dictates the route an IP packet takes 
from its source to its destination. If Yes, the rule applies to any packet with an IP 
source route. The majority of IP packets do not have source route.

Destination:

IP Addr

Type the destination IP address of the packet you want to filter. This field is ignored 
if it is 0.0.0.0.

IP Mask

Type the IP mask to apply to the Destination: IP Addr field.
