2  Check Items Included

3  Connect the Cables

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 Connect Port 0, the outside Ethernet port, to the public network:

a. Use the yellow Ethernet cable (72-1482-01) to connect the device to a switch or hub.

b. Use the orange Ethernet cable (72-3515-01) to connect the device to a cable/DSL/ISDN modem.

Step 3 Connect your PC or other network devices with an Ethernet cable (not provided) to one of the four switched inside ports (numbered 1 through 4).

Note Make sure that one of the PCs has TCP/IP installed and is configured to obtain an IP address automatically through DHCP. This allows the PC to communicate with the PIX 501 and the Internet as well as run the PDM Startup Wizard.

4  Power On the PIX 501

Follow these steps to power on the PIX Firewall:

Step 1 Connect the small, round connector of the power supply cable to the power connector on the rear panel.

Step 2 Connect the AC power connector of the power supply input cable to an electrical outlet.

Note The PIX 501 does not have a power switch. Completing Step 2 powers on the device.

5  Check the LEDs

The LINK/ACT LED indicators on the front panel of the PIX Firewall are normally solid green when a link is established and flashing green when the ports are active. Each inside Ethernet interface (1 through 4) has two LEDs to indicate the operating speed and that the physical link is established.

Note If all LEDs are operating as expected (see Table 1), this concludes the hardware installation. The pages that follow include instructions on running PDM and additional optional procedures.

Table 1 PIX 501 LEDs

LED
State
Description

POWER

Green

The device is powered on.

Off

The device is powered off.

LINK/ACT

Flashing green

Network activity, such as Internet access, is present.

Green

The correct cable is in use, and the connected equipment has power.

Off

No link is established.

   

Tip If the LINK/ACT LED does not light up, you might be using the wrong type of cable. Try replacing the yellow (straight-through) Ethernet cable with the orange (crossover) Ethernet cable.

VPN TUNNEL

Green

One or more IKE/IPSec VPN tunnels are active.

Off

No VPN tunnels are active. The default configuration does not include VPN. Thus, the VPN tunnel LED will only be enabled if VPN is added to your configuration and a VPN tunnel is then established. Also, the LED does not light up when PPTP/L2TP tunnels are established.

100 MBPS

Green

The interface is autonegotiated at 100-Mbps half or full duplex.

Flashing green

The interface is functioning at 10-Mbps half or full duplex.


6  (Optional) Install a Cable Lock

The PIX 501 includes a slot that accepts standard desktop cable locks to provide physical security for small portable equipment, such as a laptop computer. The cable lock is not included.

Follow these steps to install a cable lock:

Step 1 Attach the cable lock (not included) to the lock slot on the back panel of the PIX 501.

Step 2 Follow the directions from the manufacturer for attaching the other end of the device for securing the PIX Firewall.

7  Configuring the PIX 501

The PIX 501 comes with a factory default configuration that meets the needs of most broadband networking environments. The factory default configuration on the PIX 501 protects your inside network from any unsolicited traffic. It is configured to use DHCP on the outside interface to acquire its IP address. A default DHCP server address pool is included for hosts on the inside interface.

PDM contains a Startup Wizard that lets you easily change settings to suit your needs.

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 your 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

8  PDM Startup Wizard

The PIX 501 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 501. 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 the 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 load PDM and use the Startup Wizard:

Step 1 Use an Ethernet cable to connect your PC to one of the four switched inside ports (numbered 1 through 4) 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 LINK LED to verify that your PC has basic connectivity to the PIX Firewall on one of the inside ports (1 through 4). When connectivity occurs, the LINK LED on the front panel of the PIX Firewall lights up solid green.

Step 4 To access the Startup Wizard, use a PC connected to one of the PIX Firewall switch ports and enter the URL https://192.168.1.1/startup.html into your browser.

Note It is very important to enter the "s" in "https://192.168.1.1," which indicates a secure connection. If you enter "http://192.168.1.1" without the "s" in "https," you cannot access the PIX Firewall.

Step 5 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.

9  Alternative Ways to Access the PIX 501

You can use a serial terminal emulator from a PC or workstation connected to the Console port for local administrative access.

You can also use PDM or a console to configure Telnet access to the PIX Firewall. By default, Telnet access is not permitted. 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. For more information, refer to the Cisco PIX Firewall and VPN Configuration Guide.

Follow these steps to connect a console for local administrative access:

Step 1 Plug one end of the console cable adapter (29-0810-01) into a standard 9-pin PC serial port.

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

Refer to the Cisco PIX Firewall and VPN Configuration Guide for information about how to use the command-line interface (CLI).

10  Upgrade to DES, 3DES, or a 50-User License

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 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), 3DES (not free), or a 50-user license.

To request a free activation key for DES, complete the online form at the following website:

http://www.cisco.com/pcgi-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 and request a free 56-bit DES key.

To purchase an activation key for 3DES (PIX-501-VPN-3DES=) or a 50-user license (PIX-501-SW-10-50=), go to Cisco's ordering website:

http://www.cisco.com/public/Ordering_root.shtml

Note You can verify if you have DES, 3DES or a 50-user license features using 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 From the CLI, enter the activation-key activation-key-four-tuple command, replacing activation-key-four-tuple with the activation key obtained from Cisco.

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

Step 3 Reboot the PIX Firewall by powering it off and then on again.

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

For activation key examples or upgrade troubleshooting, refer to the Cisco PIX Firewall and VPN Configuration Guide, available at the following website:

http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_62/index.htm

Active Host Limitation

The PIX 501 supports up to 10 active hosts on the inside network, or 50 active hosts on the inside network if the optional 50-User License has been purchased. A host is considered active when any of the following statements are true:

•The host has passed traffic through the PIX Firewall during the time configured for the xlate timeout interval

•The host has an established NAT/PAT translation through the PIX Firewall

•The host has an established TCP connection or UDP session through the PIX Firewall

•The host has an established user authentication through the PIX Firewall

Refer to the System Properties>Timeout online help within PDM for the default inactivity timeout values associated with each of the preceding bulleted items.

11  Restore the Default Configuration

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

If you inadvertently erase the default configuration or need to restore the default configuration, you can restore the factory default values in one of the following ways:

•Run the Startup Wizard and click Reset PIX to Factory Default Configuration from the Starting Configuration page.

•Use PDM and click File>Reset PIX to Factory Default Configuration.

•Use PDM or a terminal emulation program and enter the following 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 optional address mask are specified, the factory-default configuration will reflect the specified IP address.

Note The config factory-default command considers both licensing and platform in creating DHCP pool sizes of 32 or 128.
