PIX 501 firewall configuration: Configuration setup

Learn how to enable administrative mode in order to allow custom configuration.

When booting up PIX firewall for the first time, you should see a screen like this:

You will be prompted to answer YES or NO as to whether or not you want to configure the PIX through interactive prompts. Answer NO, because learning how to configure the firewall is more useful than just answering a series of questions.

After that, you will be sent to a prompt that looks like this:

pixfirewall>

With the "greater than" symbol at the end of the prompt, you are in the PIX user mode. Change to privileged mode with the en or enable command. Press "enter" at the Password prompt. Here is an example:

pixfirewall> en
Password: 
pixfirewall#

You now have administrative mode to show things but would have to go into global configuration mode to configure the PIX.

In the next step we'll discuss the basic configuration of the PIX.
