I struggled quite a lot of get ASA 8.4 working on GNS3. I had 8.0(2) working and was helping to test the configurations and VPNs but now wanted to get 8.4 running such that I can prepare myself for new NAT statements and migration from 8.0(2) to 8.4(2).
Here are the steps to get it working. All links to any images or keys are removed for legal reasons. Once its gone its gone.
Download the ASA 8.4 files for GNS3 from the following address
I am afraid you will have to search google for reputable sources to get firewall ASA842 image. Please dont ask here for the image.
2. Configure GNS3 as following. ( I am using Ver 0.8.2 Beta 2, Also Tested 8.3 with Windows 7 64 bit which worked without any issues). Type the code below into relevant fields
Qemu Options: -vnc none -vga none -m 1024 -icount auto -hdachs 980,16,32
Kernel cmd line: -append ide_generic.probe_mask=0x01 ide_core.chs=0.0:980,16,32 auto nousb console=ttyS0,9600 bigphysarea=65536
Once the firewall is up and running use following activation keys
Again the activation keys are in public domain so get it using your search capabilities.
It will take a while (10-15 min) to accept the second activation key and will take the same time at first reboot.
That's all done and we have a working firewall to play with.
Now if you want to run two ASAs, you will have to change the Qemu options on the second firewall as below
Qemu Options: -vnc :2 none -vga none -m 1024 -icount auto -hdachs 980,16,32

I have posted a LAB Guide for migrating NAT from 8.2 to 8.3/8.4 Version, which is still work in progress but has a lot of stuff already added into it
