Table B-1 lists sample predefined criteria, ranges, and actions for some common

filtering goals.

Table B-1. Predefined Criteria, Ranges, and Actions for Sample Inbound Traffic Filters

Filtering Goal Criteria Path Ranges Action Path Notes

Configure a

subset of

allowed Telnet,

TFTP, and FTP

users

Criteria > Add > IP

Source Address

Client IP source

addresses

Use

dotted-decimal

format.

Action > Add >

This strategy works only if the

destination IP address is one

of the router’s interfaces and if

the protocol or well-known

port is Telnet, TFTP, or FTP.

Configure a

router to drop

BootP requests

from particular

clients

Criteria > Add >

UDP Frame > UDP

Destination Port

MAC addresses of

the BootP clients

Action > Add >

Drop

Drop inbound

Telnet traffic

Criteria > Add > IP >

TCP Frame > TCP

Destination Port

See Table 5-6 in

Chapter 5 for a list

of common TCP

port ranges.

Action > Add >

Drop

For a more secure method,

create a user-defined filter

(see Table B-2).

This filter will not stop remote

users from establishing a

Telnet session with the router.

To do that, you must also

create outbound traffic filters

on the remote circuits.
