GNS3, Windows 7 with ASA 802

NOTE: The below dose NOT work for asa842-k8.bin

This is a fairly easy task to accomplish when you know how and where all the files are so I thought I would put it all together here.
Download and install GNS3

Download  and unzip unpaker

Download and unzip gzip.

From the gzip folder copy the file “gzip.exe” to “c:\windows\System32\
Go back to the unpaker folder and open the “README.txt ” file and follow the instructions for windows. Essentially you need to open a dos prompt, cd to the unpaker folder and execute the following command “unpack.exe –format ASA8 asa802-k8.bin
The file asa802-k8.bin you need to download from www.cisco.com
Once the command completes the following files are produced.

  • asa802-k8.bin.unpacked.initrd
  • asa802-k8.bin.unpacked.vmlinuz

Start GNS3 and see the screen shot below on what to configure

You can now drag and drop an ASA onto your topology. Highlight the ASA right click on it and click on “start”, minimise the window and then right on the ASA again and console.
