Chapter 2 Installing a PIX Firewall

Before You Begin the Installation

Before You Begin the Installation

Note The information you gather here is required during configuration and is a reminder to find it while installing your PIX Firewall—before beginning the configuration. You can use this information with Chapter 9, “Installing the PIX Firewall Setup Wizard” or with the Cisco PIX Firewall Configuration Guide, Version 5.2.

Before you begin the installation, gather information about each network interface that will be connected to the PIX Firewall. If you have a PIX 506, all you need are IP addresses for the two interfaces. All other information in Table 2-1will be provided automatically in the configuration that comes with the PIX 506. For models other than the PIX 506, locate the following information before proceeding.

To prepare to configure the PIX Firewall, locate the following information:

Interface speed—The speed of each network interface. You only need to specify a value for Ethernet interface boards that do not autosense the interface’s speed, connection type, and full/half duplex support; or for Token Ring interface boards. Use the interface command to enter the speed for each interface in the configuration.

IP address and netmask—The IP address and network mask for each network interface. The

IP address for each interface must be different from any others you use in your network. Use the ip address command to enter the IP address and network mask for each interface in the configuration.

Interface nameHW—The hardware name for the interface, such as ethernet0, ethernet1, token0, token1, fddi0, fddi1, and so on. Use the nameif command to enter the hardware name for the interface in the configuration.

Interface nameSW—The software name for the interface, such as inside or outside. The inside interface must be named “inside.” All other interfaces can have any name. Note that you will need to enter this name frequently in the configuration. Use the nameif command to associate the hardware and software names in the configuration.

Security level—Used to determine the level of trust for each network interface. The outside network must have a security level of 0 and the inside network must be 100. The perimeter interfaces can be any value from 1 to 99. Use the nameif command to enter the security level in the configuration.
