Cisco ASA Firewall
is very important from the prospective of CCNP Security exam. We can setup the
ASA Firewall in Gns3 for the preparation of exam and practice. In this post we
will just discuss the setup of ASA in 64-bit as well as 32-bit Gns3 , later on
we will also discuss some interesting configurations and topologies in Gns3
with help of ASA firewall.
So let's begin the
process. First of all we need to download the ASA firewall components. Use the
following links to download the two required image files.
1. Now open gns3 and
from the menu bar follow the path
edit>preference.
2. In preference dialog
go to the qemu and click on the ASA tab.
3. now put some name in the identifier name box..
4. In the Qemu option
field put the following command in red color
as per the version of gns3.
For 32-bit Gns3 : -vnc none -vga none
-m 1024 -icount auto -hdachs 980,16,32
For 64-bit Gns3
: vnc none -vga
none -m 1024 -icount auto -hdachs 980,16,32 -m 1024 -icount auto -hdachs
980,16,32
5. Now we have to
specify the path of initrd
file and kernel file that are the two files instructed to
download in the beginning of the post.
6. In kernel cmd line
field following command is used independent of the 32 or 64 bit Gns3
Kernel cmd line :
-append ide_generic.probe_mask=0x01 ide_core.chs=0.0:980,16,32 auto nousb
console=ttyS0,9600 bigphysarea=65536
Now click on the
save button and then apply and save.
Your ASA Firewall is
ready to rock with Gns3 .
Just pick and drop
the Cisco ASA firewall to the topology field and start the ASA.
Enjoy. !!!
