3Configuring the PIX 506E

The PIX 506E comes with a factory default configuration that meets the needs of most broadband

networking environments. The factory default configuration on the PIX 506E protects your inside

network from any unsolicited traffic. It is configured to use DHCP on the outside interface to acquire an

IP address. A default DHCP server address pool is included for hosts on the inside interface.

Instances in which it might be necessary to change or make additional changes to the default

configuration include the following:

•To create administrative and Telnet passwords

Note We highly recommend that you change the administrative and Telnet passwords from

their default settings to secure the administration of the PIX Firewall.

•To configure Point-to-Point Protocol over Ethernet (PPPoE) or a static IP address for an outside

interface

•To configure VPN and Auto Update features

ThePIX 506Econtainsanintegratedconfigurationutility

called Cisco PIX Device Manager (PDM). PDM is a web

browser-basedconfigurationtooldesignedtohelpyouset

up, configure, and monitor the PIX Firewall. PDM is

preinstalled on the PIX 506E. To access PDM, make

sure JavaScript and Java are enabled in your web

browser. For best performance, we recommend that

you use Microsoft Internet Explorer 5.5 or a higher

release. Refer to the Cisco PIX Device Manager

Installation Guide for more information on operating

system and web browser environments supported by

PDM.

PDM Version 2.0 and higher releases include a Startup Wizard for initial configuration. Follow these steps

to use the Startup Wizard:

Step 1 If you have not already done so, use an Ethernet cable to connect your PC to the inside port

(Ethernet 1) on the rear panel of the PIX Firewall.

Step 2 Configure your PC to use DHCP (to receive an IP address automatically from the

PIX Firewall) or assign a static IP address to your PC by selecting an address out of the

192.168.1.0 network.

Note The inside interface of the PIX Firewall is assigned 192.168.1.1, so choose a different

IP address.

Step 3 Check the ACT LED on the rear panel of the PIX Firewall (see Table 2 on page 11) to verify

that your PC has basic connectivity to the inside port (Ethernet 1). When connectivity occurs,

the ACT LED next to the port lights up solid green.

Step 4 To access the Startup Wizard, use a PC connected to the inside port and enter the URL

https://192.168.1.1/startup.html into your browser.

Note Remember to add the “s” to “https” or the connection fails. HTTPS (HTTP over SSL)

provides a secure connection between your browser and the PIX Firewall that you are

using PDM to configure or monitor.

Step 5 Do not enter your username or password, just press Enter.

Step 6 Accept the certificates and follow the instructionsin theStartup Wizard. Foronline help, click

the Help button at the bottom of the Startup Wizard window.

4Optional Maintenance and Upgrade Procedures

Upgrade to DES or 3DES

Note The following instructions are applicable to PIX Firewall Version 6.2 and higher releases. If

you are not running PIX Firewall Version 6.2, refer to the Quick Start Guide for the version

of software installed on your PIX Firewall.

To upgrade features you did not specify at the time of purchase, you need to use an activation key. The

activation key lets you add software features to the PIX 506E, such as DES or 3DES.

To obtain a free DES (56-bit) license key for the PIX Firewall, use the IPSec 56-bit Customer

Registration form. Accessing this form requires prior registration on Cisco.com at

http://www.cisco.com/register. However, access to this form does not require a purchase or service

contract. You can register as a guest and then proceed to fill out the form. The form is available at the

following website:

http://www.cisco.com/cgi-bin/Software/FormManager/formgenerator.pl?pid=221&fid=324

Note If you are unable to access this form because you do not have a CCO login, send an e-mail to

licensing@cisco.com. In the e-mail include the PIX Firewall serial number as it appears in the

show version command output and request a free 56-bit DES key.

You must purchase a 3DES (168-bit) license key, or have a service contract, to obtain a 3DES license

key. If you have already purchased a 3DES upgrade, and you have your Cisco PIX Firewall 3DES

upgrade document with the entitlement number printed on it, you can register your license key for use

on your PIX Firewall with the License Registration form. Accessing this form also requires prior

registration on Cisco.com at http://www.cisco.com/register.

The License Registration form is available at the following website:

http://www.cisco.com/cgi-bin/Software/FormManager/formgenerator.pl?pid=221&fid=301

You must also purchase or have a service contract to download PIX Firewall software. Enter the

activation key only after you have downloaded an image—not from the command line or without

rebooting first.

Note You can verify if you have the DES or 3DES feature by entering the show activation-key command.

Follow these steps to use an activation key:

Step 1 Ensure that the image in Flash memory and the Running Image are the same.

Step 2 Make sure that you are in config mode to enter a new activation key.

Step 3 From the CLI, enter the activation-key activation-key-four-tuple command, replacing

activation-key-four-tuple with the activation key obtained from Cisco.

Step 4 Reboot the PIX Firewall by powering it off and then on again.

After the key update is complete, the system reloads to update the running image.

Restore the Default Configuration

You can restore your configuration back to the factory default values in one of the following ways:

•You can start the Startup Wizard at: https://192.168.1.1/startup.html

•Enter the following CLI commands:

Refer to the following website for detailed command information and configuration examples:

http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_62/cmdref/index.htm

The Cisco TAC website is available to all customers who need technical assistance. To access the TAC

Website go to:

http://www.cisco.com/tac

Command Description

Step 1 configure factory-default [<inside

ip address> [address mask]] 1

1. If the optional inside IP address and optional address mask are specified, the factory-default configuration

will reflect the specified IP address.

Caution Entering the configure factory-default command erases the current running configuration.

Erases the running configuration and replaces it with

the factory default configuration.

Step 2 write memory Writes the factory default configuration to Flash

memory.

Alternative Ways to Access the PIX 506E

You can access the command-line interface (CLI) for administration using the console port on the PIX

Firewall. To do so, you must run a serial terminal emulator on a PC or workstation.

To connect a console for local administrative access:

Step 1 Plug one end of the console cable adapter into a standard 9-pin PC serial port.

Step 2 Plug one end of the blue console cable (72-1259-01) into the PC terminal adapter.

Step 3 Plug the other end of the blue console cable into the Console port.

Step 4 Configure the PC terminal emulation software or terminal for 9600 baud, 8 data bits, no

parity, and 1 stop bit.

You can also access the CLI using SSH/Telnet to the PIX Firewall. By default, SSH/Telnet access is not

permitted. Use PDM or the console to configure SSH/Telnet access to the PIX Firewall. To Telnet to

the PIX Firewall from the outside perimeter of the firewall, configure an outside IP address and IPSec

for a secure Telnet session. Refer to the Cisco PIX Firewall and VPN Configuration Guide for more

information about how to use the command-line interface (CLI).
