How to run ASA 8 firewall on GNS3 0.7.3

In this post i will explain you how to configure the ASA version 8 firewall in GNS3. Since GNS3 0.7.3 this only took me 5 minutes.

 

I assume you already have Qemu running.

 

  • Start GNS3
  • Open the menu, go to “Edit” then “Preferences”.
  • Open the “Qemu” tab.
  • Open the “ASA” tab.
  • Select the “Initrd” file. The filename I used was “asa802-k8.initrd.gz”. Press Open.
  • Select the “Kernel” file. The filename I used was “asa802-k8.kernel”. Press Open.
  • Hit the “Save” button. Press “Ok”.
  • Click and drag an ASA Firewall to your topology screen and press the “Start” button.
  • Minimze your Qemu screen (don’t close it).
  • Press the “Console” button.
  • After it’s done booting wait about 1 minute then type in the following:
    /mnt/disk0/lina_monitor
  • Voila! you have a running ASA 8 Firewall in GNS3.

 

That’s all there is to it! Thanks to CCNA Tools for the information, this is where i found the explanation to do this.

 

Now the only thing left to do is make sure we have ASA labs here at GNS3Vault. I’m more of a routing & switching guy so if you have anything to share…please do!

    I am running GNS3 v0.7.4 on a windows 7 64bit laptop. I followed all the steps above and I got this error message when I tried to load an ASA firewall. Dynamips error: 202 Unknown-command ‘clean’. What does this mean and how can I fix this?
    thank you,

    Has anyone seen the fix for the ASA in GNS3 doing the reboot. I have patched qemu per GNS3 website and followed all the sites I can find on the internet to get asa842-k8 (the 2 files) to work in GNS3. I have copied and pasted several different Qemu Options and Kernel CMD opitons and still get the rebooting error. I have a Windows 7 64bit Lenovo with 6 gig ram. Any help would be greatly appreciated?

    I followed everything and used the same config files as suggested. I start the asa and it goes from red to green… When I open the console nothing happens. I am never prompted to enter the /mnt/disk0/lina_monitor command as it just stays with nothing happening.

    I don’t get any errors or anything.
