Table 55   Menu 21.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.

Port #

Type the destination port of the packets you want to filter. The field range is 0 to 

65535. A 0 field is ignored.

Port # Comp

Select the comparison to apply to the destination port in the packet against the value 

given in Destination: Port #. Choices are None, Less, Greater, Equal or Not 

Equal.

Source:

IP Addr

Type the source IP Address of the packet you want to filter. A 0.0.0.0 field is ignored.

IP Mask

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