Simulate a Cisco ASA firewall using GNS3

There are very few simulators capable of simulating the ASA firewall. Currently, GNS3 is one of the most outstanding ones. There are many introductions on the Internet, but the method of simulating the ASA is also very messy, after several days of research and testing, I can simulate the ASA firewall, but it is not perfect.

Step 1.

Install gns3-0.8.4-rc3-all-in-one.exe and install all the required software.

Step 2.

Start GNS3 and configure it as follows:

Here, you need to calculate the IDEL value every time you add a route device to ios to prevent high CPU usage on your computer.

The first time you run the device, you need to execute the following command: single mode/Multi mode depends on the asa Kernel used by the simulator)

Asa single mode/mnt/disk0/lina_monitor

Asa multi-mode/mnt/disk0/lina-m
