Chapter 2 Installing a PIX Firewall

Software Installation Notes

Follow these steps to download an image over TFTP using the monitor command:

Step 1 Immediately after you power on the PIX Firewall and the startup messages appear, send a BREAK

character or press the Esc (Escape) key.

Note If you are using HyperTerminal with Windows 95, you can press ctrl-break to

activate a BREAK or press the Esc (Escape) key. Depending on which service

pack is installed, Windows NT HyperTerminal may not be able to send a BREAK

character, but the Esc key should work. Refer to the Windows NT documentation

for more information.

The monitor> prompt appears.

Step 2 If desired, enter a question mark (?) to list the available commands.

Step 3 Use the interface command to specify which interface the ping traffic should use. If a PIX 515 or a

PIX 525 have only two interfaces, the monitor command defaults to the inside interface.

Step 4 Use the address command to specify the IP address of the PIX Firewall unit’s interface.

Step 5 Use the server command to specify the IP address of the remote server.

Step 6 Use the file command to specify the filename of the PIX Firewall image. In UNIX, the file needs to be

world readable for the TFTP server to access it.

Step 7 If needed, enter the gateway command to specify the IP address of a router gateway through which the

server is accessible.

Step 8 If needed, use the ping command to verify accessibility. If this command fails, fix access to the server

before continuing.

Step 9 Use the tftp command to start the download.
