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.

7
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
[e-mail]. 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.

9
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.

10
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).
