Testing Pix related labs can be difficult without the necessary features. In this tutorial, you will learn how to find and use an unrestricted license on your virtual pix firewall.  This will not work on an actual Pix firewall. Only GNS3 and only for testing.



How to obtain an unrestricted license on your own

  1. Open google.com
  2. Enter “This Platform has an unrestricted (UR) license” (with quotes)
  3. Search the results until you find a valid ‘show version’ with a serial number and activation key
  4. Copy the serial number
  5. Open a new tab and go to google.com again
  6. Paste the serial number followed by “in hex”
    ex: [405400750 in hex                 ]
  7. The resulting hex  number will be used as the serial number in GNS3



Configure PEMU to use the unrestricted Pix license

  1. Open Gns3
  2. Create a new project file
    • check save NVRAMS and other disk files
    • click ‘Ok’
  3. Configure Pemu Preferences
    • Go to the ‘Edit > Preferences’ menu
    • Make sure the pemuwrapper path is correct
    • Locate a Pix image on your hard drive
    • Enter the hex version of the serial number found with google’s help
    • Click ‘Ok’
  4. Drag a Pix Icon onto the lab
  5. Start the firewall
  6. Console into the firewall
  7. Type ‘enable’ to enter enable mode
  8. Press enter when prompted for a password
  9. Type ‘config t’ to enter config mode
