28.4.1 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.x.1 – TCP/IP Filter Rule, as shown next.
Figure 160 Menu 21.1.x.1 TCP/IP Filter Rule
The following table describes how to configure your TCP/IP filter rule.

FIELD DESCRIPTION
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.
