2 Install the PIX 515E

Follow these steps to install the PIX 515E:


Step 1 Install the rubber feet onto the five, round, recessed areas on the bottom of the chassis.


Note The chassis is also rack-mountable. For rack-mounting and failover instructions, refer to the Cisco PIX Firewall Hardware Installation Guide.


Step 2 Use the yellow Ethernet cable (72-1482-01) provided to connect the outside 10/100 Ethernet interface, Ethernet 0, to a DSL modem, cable modem, or switch.

Step 3 Use the other yellow Ethernet cable (72-1482-01) provided to connect the inside 10/100 Ethernet interface, Ethernet 1, to a switch or hub.

Step 4 Connect the power cable to the rear of the PIX 515E and a power outlet.

Step 5 Power up the PIX 515E. The power switch is located at the rear of the chassis.


Note For additional hardware installation procedures, refer to the Cisco PIX Firewall Hardware Installation Guide.



3 Configure the PIX 515E

The PIX 515E comes with a factory-default configuration that meets the needs of most small and medium business networking environments. A default DHCP server address pool is included for hosts on the inside interface. The factory-default configuration on the PIX 515E protects your inside network from unsolicited traffic.

By default, the PIX 515E denies all inbound traffic through the outside interface. Based on your network security policy, you should also consider configuring the PIX 515E to deny all ICMP traffic to the outside interface, or any other interface you deem necessary, by entering the icmp command. For more information about the icmp command, refer to the Cisco PIX Firewall Command Reference.

The PIX 515E contains an integrated web-based configuration tool

called the Cisco PIX Device Manager (PDM), that is designed to help you set up the PIX Firewall. PDM is preinstalled on the PIX 515E. To access PDM, make sure that JavaScript and Java are enabled in your web browser. Refer to the Cisco PIX Device Manager Installation Guide for more information on the operating system and web browser environments supported by PDM.

PDM includes a Startup Wizard for simplified initial configuration of your PIX Firewall. With just a few steps, the PDM Startup Wizard enables you to efficiently create a basic configuration that allows packets to flow through the PIX Firewall from the inside network to the outside network securely. Follow these steps to use the Startup Wizard:


Step 1 If you have not already done so, connect the inside Ethernet 1 interface of the PIX 515E to a switch or hub using the Ethernet cable. To this same switch, connect a PC for configuring the PIX 515E.

Step 2 Configure your PC to use DHCP (to receive an IP address automatically from the PIX 515E) or assign a static IP address to your PC by selecting an address out of the 192.168.1.0 network. (Valid addresses are 192.168.1.2 through 192.168.1.254 with a mask of 255.255.255.0 and default route of 192.168.1.1.)


Note The inside interface of the PIX 515E is assigned 192.168.1.1 by default, so this address is unavailable.


Step 3 Check the LINK LED on the PIX 515E Ethernet 1 interface. When connectivity occurs, the LINK LED on the Ethernet 1 interface of the PIX Firewall and the corresponding LINK LED on the switch or hub lights up solid green.

Step 4 To access the Startup Wizard, use the PC connected to the switch or hub and enter the URL https://192.168.1.1/startup.html into your Internet browser.


Note Remember to add the "s" in "https" or the connection fails. HTTPS (HTTP over SSL) provides a secure connection between your browser and the PIX 515E.


Step 5 Leave both the username and password boxes empty. Press Enter.

Step 6 Select Yes to accept the certificates and follow the instructions in the Startup Wizard to set up your PIX 515E. For online Help, click the Help button at the bottom of the Startup Wizard window.


4 Example Configurations

The following section provides configuration examples for two common PIX 515E configuration scenarios: hosting a web server on a DMZ network and establishing a site-to-site VPN connection with other business partners or remote offices. Use these examples to set up your network. Substitute network addresses and apply additional policies as needed.

DMZ Configuration

A demilitarized zone (DMZ) is a neutral zone between private (inside) and public (outside) networks. A DMZ allows you to have a presence on the public Internet, while protecting private network resources that are accessed by users on the public Internet; for example, mail servers or web servers. The illustration below shows a sample network topology that is common to most DMZ implementations using the PIX 515E, in which the web server is on the DMZ interface. HTTP clients from the inside and the outside networks are able to access the web server securely.

In the illustration below, an HTTP client (10.10.10.10) on the inside network initiates HTTP communications with the DMZ web server (30.30.30.30). HTTP access to the DMZ web server is provided for all clients on the Internet; all other communications are denied. The network is configured such that the range of available IP addresses on the DMZ interface are between 30.30.30.50-30.30.30.60. There are two publicly routable IP addresses available, one for the PIX 515E outside interface (209.165.156.10) and one for the translated DMZ server (209.165.156.11). Because the DMZ server is located on a private DMZ network, it is necessary to translate its private IP address to a public (routable) IP address. This public address allows external clients HTTP access to the DMZ server as though it was located on the Internet. Use PDM to quickly configure your PIX 515E for secure communications between HTTP clients and web servers.

Step 1 Manage IP Pools for Network Translations

For an inside HTTP client (10.10.10.10) to access the web server on the DMZ network (30.30.30.30), it is necessary to define an IP pool (30.30.30.50-30.30.30.60) for the DMZ interface. Similarly, an IP pool for the outside interface (209.165.156.10) is required for the inside HTTP client to communicate with any device on the public network. Use PDM to manage IP pools efficiently and easily to facilitate secure communications between protected network clients and devices on the Internet.

a. Launch PDM.

b. Click the Configuration button at the top of the PDM window.

c. Select the Translation Rules tab.

d. Click the Manage Pools button and a new window appears, allowing you to add or edit global address pools.


Note For most configurations, global pools are added to the less secure, or public, interfaces.


In the Manage Global Address Pools window:

a. Select the dmz interface.

b. Click the Add button.

In the Add Global Pool Item window:

a. Select dmz from the Interface drop-down menu.

b. Click the Range radio button to enter the IP address range.

c. Because the range of IP addresses for the DMZ interface is 30.30.30.50- 30.30.30.60, enter these values in the two fields.

d. Enter a unique Pool ID (in this case, enter 200).

e. Click the OK button to go back to the Manage Global Address Pools window.


Note You can also select PAT or PAT using the IP address of the interface if there are limited IP addresses available for the DMZ interface.


Because there are only two public IP addresses available, with one reserved for the DMZ server, all traffic initiated by the inside HTTP client exits the PIX 515E using the outside interface IP address. This allows traffic from the inside client to be routed to and from the Internet.

In the Manage Global Address Pools window:

a. Select the outside interface.

b. Click the Add button.

When the new window comes up:

a. Select outside from the Interface drop-down menu.

b. Click the Port Address Translation (PAT) using the IP address of the interface radio button.

c. Assign the same Pool ID for this pool as in Step d above (200).

d. Click the OK button.

Once the pools are configured, confirm their values before applying the rules to the PIX 515E.

Confirm the configurations:

a. Click the OK button.

b. Click the Apply button in the main window.

Step 2 Configure Address Translations on Private Networks

Network Address Translation (NAT) replaces the source IP addresses of network traffic traversing between two PIX interfaces. This translation prevents the private address spaces from being exposed on public networks and permits routing through the public networks. Port Address Translation (PAT) is an extension of the NAT function that allows several hosts on the private networks to map into a single IP address on the public network. PAT is essential for small and medium businesses that have a limited number of public IP addresses available to them.

To configure NAT between the inside and the DMZ interfaces for the inside HTTP client, complete the following steps starting from the main PDM page:

a. Select the Translation Rules tab. Ensure that the Translation Rules radio button is selected.

b. Right click in the gray area below the Manage Pools button and select Add.

c. In the new window, select the inside interface.

d. Enter the IP address of the client (10.10.10.10).

e. Select 255.255.255.255 from the Mask drop-down menu.


Note You can select the inside host by clicking on the Browse button.


f. Select the DMZ interface on which the translation is required.

g. Click the Dynamic radio button in the Translate Address to section.

h. Select 200 from the Address Pools drop-down menu for the appropriate Pool ID.

i. Click the OK button.


Note Enter the entire network range (10.10.10.0) or select the network using the Browse button and select the Pool ID if there are multiple HTTP clients.


j. Click the OK button.

k. Click the Proceed button. Check the displayed configuration for accuracy.

l. Click the Apply button to configure the PIX Firewall.

Repeat the steps to configure interface PAT between the inside and outside interfaces. The procedure remains the same, except the interface on which the translation is required is now the outside interface and the Dynamic address pool should now indicate the interface PAT keywords.

The configurations should display as shown below:

Step 3 Configure External Identity for the DMZ Web Server

The DMZ server is easily accessible by all hosts on the Internet. This configuration requires translating the DMZ server IP address so that it appears to be located on the Internet, enabling outside HTTP clients to access it unaware of the firewall. Complete the following steps to map the DMZ IP address (30.30.30.30) statically to a public IP address (209.165.156.11):

a. Right click in the gray area under the Translation Rules tab.

b. Select Add.

c. Select dmz from the drop-down menu of interfaces.

d. Enter the server IP address (30.30.30.30) or select the server by clicking on the Browse button.

e. Select 255.255.255.255 from the Mask drop-down menu.

f. Click the Static radio button.

g. Enter the external IP address (209.165.156.11). The Advanced button allows you to configure features such as limiting the number of connections per static entry and DNS rewrites.

h. Click the OK button.

i. Confirm the values that you entered. Click the Apply button.

The configurations should display as shown below:

Step 4 Provide HTTP Access to the DMZ Web Server

In addition to configuring address translations, you must configure the PIX 515E to allow the specific traffic types from the public networks. To configure access lists for HTTP traffic originating from any client on the Internet to the DMZ web server, complete the following:

a. Click the Configuration button at the top of the PDM window.

b. Select the Access rules tab.

c. In the table, right click and select Add.

The Edit Rule window opens up, allowing you to select the ACL rules to permit/deny traffic.

a. Under Action, select permit from the drop-down menu to allow traffic through the firewall.

b. Under Source Host/Network, click the IP Address radio button.

c. Select outside from the Interface drop-down menu.

d. Enter the Source Host/Network information (0.0.0.0 for any host or network).

e. Under Destination Host/Network, click the IP Address radio button.

f. Select dmz from the Interface drop-down menu.

g. Enter 30.30.30.30 in the IP address box.

h. Select 255.255.255.255 from the Mask drop-down menu.


Note Alternatively, you can select the Hosts/Networks in both cases by clicking on the respective Browse buttons.


Select the type of traffic that you would permit:


Note HTTP traffic is always directed from any TCP source port number toward a fixed destination TCP port number 80.


i. Select the TCP radio button, under Protocol and Service.

j. Select "=" (equal to) from the Service drop-down menu under Source Port.

k. Scroll through the options, and select Any.

l. Select "=" (equal to) from the Service drop-down menu under Destination Port.

m. Scroll through the options, and select HTTP.

n. Click the OK button.


Note For additional features, such as system log messages by ACL, check the radio button at the top and click the More options button. You can provide a name for the access rule in the window at the bottom.


o. Check the various fields for accuracy and click the OK button.


Note Although the destination address specified above is the private address of the DMZ web server (30.30.30.30), HTTP traffic from any host on the Internet destined for 209.165.156.11 is permitted through the PIX 515E. This is made possible by the translation (30.30.30.30 = 209.165.156.11).


p. Click the Apply button in the main window.

The configurations should display as shown below:

The HTTP clients on the private and public networks can now securely access the DMZ web server.


Site-to-Site VPN Configuration

Site-to-site VPN (Virtual Private Networking) features provided by the PIX 515E enable businesses to securely extend their networks across low-cost public Internet connections to business partners and remote offices worldwide. A VPN connection allows you to send data from one location to another over a secure connection, or "tunnel," by first strongly authenticating both ends of the connection, and then automatically encrypting all data sent between the two locations. Some models of the PIX 515E include a VPN Accelerator Card+ (VAC+), which provides significantly improved VPN throughput. You can purchase a VAC+ as an add-on for other PIX 515E models.

PDM provides an easy-to-use VPN Wizard that can quickly guide you through the process of configuring a site-to-site VPN in five simple steps. The illustration below shows an example VPN tunnel between two PIX 515E, and will be referenced in the following steps.

Step 1 Start the VPN Wizard

Use PDM to configure PIX 1. In the main PDM page, select the VPN Wizard option from the Wizards drop-down menu. This opens the VPN Wizard page.

At the first VPN Wizard page, do the following:

a. Select the Site to Site VPN option.


Note The Site to Site VPN option connects two IPSec security gateways, which can include PIX Firewalls, VPN concentrators, or other devices that support site-to-site IPSec connectivity.


b. Select outside from the drop-down menu as the enabled interface for the current VPN tunnel.

c. Click the Next button to continue.

Step 2 Configure the VPN Peer

a. Enter the Peer IP Address (PIX 2) and select an authentication key (for example,"CisCo"), which is shared for IPSec negotiations between both PIX 515E units.


Note To configure PIX 2, enter the IP address for PIX 1 (1.1.1.1) and the same Pre-shared Key (CisCo).


b. To use X.509 certificates for authentication, check the Certificate radio button and the applicable option for the peer identity, FQDN (Fully Qualified Domain Name) or IP Address. If the peer identity is its FQDN, enter the exact name in the text field.

c. Click the Next button to continue.

Step 3 Configure the IKE Policy

This step is comprised of two windows:

1. Configure the IKE negotiation parameters.

In most cases, the default values are sufficient to establish secure VPN tunnels between two peers.

a. Select the Encryption (DES/3DES/AES), Authentication algorithms (MD5/SHA), and the Diffie-Hellman group (1/2/5) used by the PIX 515E during an IKE security association. Confirm all values before moving to the next window.


Note When configuring PIX 2, enter the exact values for each of the options that you selected for PIX 1. Encryption mismatches are a common cause of VPN tunnel failures and can slow down the process.


b. Click the Next button to continue.

2. Configure the IPSec parameters.

a. In the second window, select the Encryption algorithm (DES/3DES/AES) and Authentication algorithm (MD5/SHA). Confirm all values before continuing to the next window.


Note When configuring PIX 2, enter the exact same values for each of the options that you selected for PIX 1. Encryption and algorithm mismatches are a common cause of VPN tunnel failures and can slow down the process.


b. Click the Next button to continue.

Step 4 Configure Internal Traffic

This step is comprised of two windows:

1. Select network traffic on the local PIX 515E encrypted through the VPN tunnel.

a. Select the Local Host/Network based on the IP Address, Name, or Group.


Note Use the Browse button to select from preconfigured groups.


Add or remove networks dynamically from the selected panel by clicking on the >> or << buttons respectively. Traffic from Network A (10.10.10.0) is encrypted by PIX 1 and transmitted through the VPN tunnel.

b. Click the Next button to continue.

2. Select traffic permitted from the remote PIX Firewall.

a. In the second window, select VPN traffic for remote network configuration. For PIX 1, the remote network is Network B (20.20.20.0) so traffic encrypted from this tunnel is permitted through the tunnel.


Note When configuring PIX 2, ensure that the values are correctly entered. The remote network for PIX 1 is the local network for PIX 2 and vice versa.


b. Click the Finish button to complete the configuration.

Step 5 View and Enable VPN Commands

If you enabled preview commands, you will see this page:

To enable preview commands:

a. In the main PDM page, select Options.

b. Select Preferences and check the Preview commands before sending to firewall box.

Check the configuration to ensure that all values are entered correctly. Click the Send button to enable PIX 1 for site-to-site VPN communication with PIX 2.


This concludes configuration for PIX 1. When configuring PIX 2, enter the exact same values for each of the options that you selected for PIX 1. Mismatches are a common cause of VPN configuration failures.

Alternative Ways to Access the PIX 515E

You can access the 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.


Step 1 Connect the blue console cable so that you have a DB-9 connector on one end as required by the serial port for your computer, and the RJ-45 connector on the other end.


Note Use the console port to connect to a computer to enter configuration commands. Locate the blue console cable from the accessory kit. The blue console cable assembly consists of a null-modem cable with RJ-45 connectors and a DB-9 connector.


Step 2 Connect the RJ-45 connector to the PIX 515E console port, and connect the other end to the serial port connector on your computer.

If your PIX 515E has a four-port Ethernet circuit board already installed, the Ethernet circuit boards are numbered as shown in the illustration below. The four-port Ethernet circuit board is required to access the PIX 515E unrestricted license.

If your PIX 515E has one or two single-port Ethernet circuit boards installed in the auxiliary assembly on the left of the unit at the rear, the circuit boards are numbered top to bottom so that the top circuit board is Ethernet 2 and the bottom circuit board is Ethernet 3. (Using more than one Ethernet circuit board requires the PIX 515E-unrestricted license for access. If a four-port FE card is used with the restricted license, only one network interface is activated.)


Note If you need to install an optional circuit board, refer to the "Installing a Circuit Board in the PIX 515E" section in the Cisco PIX Firewall Hardware Installation Guide.


If you have a second PIX 515E to use as a failover unit, install the failover feature and cable as described in the "Installing Failover" section in the Cisco PIX Firewall Hardware Installation Guide.

Step 3 Connect the inside, outside, or perimeter network cables to the interface ports. Starting from the top left, the connectors are Ethernet 2, Ethernet 3, Ethernet 4, and Ethernet 5. The maximum number of allowed interfaces is six with an unrestricted license.


Note Do not add a single-port circuit board in the extra slot below the four-port circuit board because the maximum number of allowed interfaces is six.


Step 4 Power on the unit from the switch at the rear to start the PIX 515E. Do not power on the failover units until the active unit is configured.

Opening a TAC Case

Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

To open a case by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
