New and Changed Information

New Software Features in Release 12.0(5)T

The following new software enhancements are supported by the Cisco 802 IDSL and 804 IDSL routers

Cisco IOS Firewall Feature Set for the Cisco 802 IDSL and 804 IDSL Routers

Cisco IOS Firewall Feature Set is not new to Release 12.0(5)T; however, the Cisco IOS Firewall Feature

Set combined with IPSec is new to this release. Enhancements to the Cisco IOS Firewall feature set are

now available on the Cisco 802 IDSL and 804 IDSL routers. This feature set is available on the

IP/Internet DSL/FW/IPSec56 and IP/Internet DSL/IPX/FW/ IPSec56 images only. This feature set

provides the following additional capabilities:

• Context Based Access Control (CBAC)

• Java Blocking

• Denial of Service

• Real-time Alerts and Audit Trails

The Cisco IOS Firewall Feature Set feature module provides several sample firewall configurations,

including the following examples for small-office environments:

• IP network to Internet

• Remote office network to corporate office network

If you want to configure a firewall in an IP-network-to-Internet network, you can use the Cisco 800 Fast

Step application (recommended for inexperienced network administrators) or the Cisco IOS software

command-line interface (CLI) (recommended for more experienced network administrators). You can

also configure a firewall by using Cisco ConfigMaker software version 2.3.

With the Cisco 800 Fast Step application, you can configure CBAC only. For information on how to use

the Cisco 800 Fast Step application, refer to the application online help.

If you want to configure a firewall in a remote-office-to-corporate-office network, you must use the

Cisco IOS CLI. For information on how to configure a firewall using the CLI, refer to the following

online documents:

• Cisco IOS Firewall Feature Set feature module document

• Security Configuration Guide

• Security Command Reference

IPSec Network Security

The IPSec network security feature is now available on the Cisco 802 IDSL and 804 IDSL routers

(IP/Internet DSL/FW/IPSec56 and IP/Internet DSL/IPX/FW/ IPSec56 images only). This feature

supports the 56-bit Data Encryption Standard (DES); it does not support the triple DES. Enabling this

feature can impact your router performance.

IPSec is a framework of open standards that provides data confidentiality, data integrity, and data

authentication between participating peers, such as two routers. IPSec provides these security services

on IP datagrams. For information on configuring this feature, refer to the Cisco IOS Release 12.0

Security Configuration Guide.
