1 Check Items Included

2 Installing the PIX 506E

Follow these steps to connect the cables:

Step 1 Place the chassis on a flat, stable surface. The chassis is not rack mountable.

Step 2 Use the yellow Ethernet cable (72-1482-01) provided to connect the outside Ethernet interface, Ethernet 0, to a DSL modem, cable modem, or router.

Step 3 Use the other Ethernet cable (72-1482-01) provided to connect the inside Ethernet interface, Ethernet 1, to a switch or hub.

Note Make sure that one of the PCs has TCP/IP installed and is configured to obtain an IP address automatically through DHCP. Installing TCP/IP and configuring DHCP allows the PC to communicate with the PIX 506 and the Internet as well as run the PDM Startup Wizard.

Follow these steps to power on the PIX Firewall:

Step 1 Connect the power supply with the power cable.

Step 2 Connect the small, square connector of the power supply cable to the power connector on the rear panel.

Step 3 Connect the AC power connector of the power supply input cable to an electrical outlet.

Step 4 Set the power switch to the on (|) position.

Step 5 Check the power LED, if it is green, then the device is powered on. For more information, refer to the "Check the LEDs" section.

3 Configuring 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.

By default, the PIX Firewall denies all inbound traffic through the outside interface. Based on your network security policy, you should consider configuring the PIX Firewall to deny all ICMP traffic to the outside interface, or any other interface you deem necessary, by entering the icmp command. The icmp command controls responses to ICMP traffic that is directed at one of the PIX Firewall interfaces. If no ICMP control list is configured, then the PIX Firewall will respond to all ICMP requests received on any interface (including the outside interface).

For more information about the icmp command, refer to the Cisco PIX Firewall Command Reference.

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 (no password) 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

The PIX 506E contains an integrated configuration utility called Cisco PIX Device Manager (PDM). PDM is a web browser-based configuration tool designed to help you set 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. 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 outside 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) 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 Leave both the userword and password boxes empty. Press Enter.

Step 6 Accept the certificates and follow the instructions in the Startup Wizard. For online Help, click the Help button at the bottom of the Startup Wizard window.

4 Optional Maintenance and Upgrade Procedures

Upgrade to DES or 3DES/AES

Note The following instructions apply to PIX Firewall Version 6.2 and higher releases. If you are not running PIX Firewall Version 6.2 or higher, refer to the Quick Start Guide for the version of software installed on your Cisco 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 Firewall, such as DES(Free) or 3DES/AES, or upgrade the user license at an additional cost.

Note PDM will not work unless you have at minimum the DES license installed.

If you are a registered user of Cisco Connection Online and would like to obtain a DES or a 3DES/AES license key, or upgrade your user license for the PIX Firewall, go to the following website:

http://www.cisco.com/pcgi-bin/Software/FormManager/formgenerator.pl

If you are not a registered user of Cisco Connection Online, go to the following website:

http://www.cisco.com/pcgi-bin/Software/FormManager/formgenerator.pl

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 DES or a 3DES/AES license key.

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

Note You can verify if you have DES, 3DES/AES, or user license by entering the show activation-key command.

To obtain an activation key, you need a Product Authorization Key, which you can purchase from your Cisco account representative. After obtaining the Product Authorization Key, register it on the Web to obtain an activation key by performing the following steps:

Step 1 Connect a web browser to one of the following websites (the URLs are case-sensitive):

•Go to the following website if you are a registered user of Cisco Connection Online: http://www.cisco.com/pcgi-bin/Software/FormManager/formgenerator.pl

•Go to the following website if if you are not a registered user of Cisco Connection Online: http://www.cisco.com/pcgi-bin/Software/FormManager/formgenerator.pl

Step 2 Obtain the serial number for your PIX Firewall by entering the show version command.

Step 3 Enter the following information, when prompted:

•Your Product Authorization Key

•The serial number for your PIX Firewall

•Your e-mail address

The activation key is generated automatically and sent to the e-mail address that you provide.

Follow these steps to use the activation key:

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

Step 2 From the command-line interface (CLI) enter the configure terminal command to start configuration mode.

Step 3 Enter the activation-key activation-key-four-tuple command. Replace activation-key-four-tuple with the activation key you obtained with your new license.

Step 4 Use the exit command to exit configuration mode. This command is the same as the quit command.

Step 5 Enter the write memory command to save the configuration.

Step 6 To use the new activation key, reboot the PIX Firewall.

For more information on activation key examples or upgrading software, refer to the Cisco PIX Firewall and VPN Configuration Guide.

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:

 
Command
Description

Step 1 

configure factory-default [<inside ip address> [address mask]] 1

Erases the running configuration and replaces it with the factory default configuration.

Step 2 

write memory

Writes the factory default configuration to Flash memory.

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

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

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.

For information on how to access the PIX Firewall configuration mode, refer to the "Accessing Configuration Mode" section in Chapter 1, "Getting Started" in the Cisco PIX Firewall and VPN Configuration Guide.

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 PIX 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 CLI.
