Technology

We have been chasing technology in all possible ways and we try our best to keep on the same steps as the technology. To be sure that we are on the same platform, we need to practice the devices. For the practice, we would need a virtual environment. So why not start with the installation of the FortiGate Firewall in GNS3? The easiest way of installation in a limited specification of a machine has described below.

All the steps are to be followed in the right order and not even one step should be missed.

When you are trying to install FortiGate Firewall in GNS3 then you must ensure one thing that the GNS3 software version must be the same as the GNS3 VM version.

STEP 1
In my case, I installed GNS3 2.2.5 version on my laptop, and the same GNS3 VM version 2.2.5 was installed in VMware Workstation.

If you are curious about the installation of GNS3 VM in VMware Workstation, then you can contact us.

After successful installation of GNS3 VM, we will check the KVM support if it is available or not. If not, then you must enable Virtualization and verify that it is true.

STEP 2
After opening GNS3, we will Configure GNS3 VM Server.

STEP 6
Since we have already selected GNS3 VM to run FortiGate, the other two options are not highlighted. Click Next > In Qemu Settings click Next.

STEP 7
In this window, the list of FortiGate Firewall KVM image versions with extension .qcow2 is visible. The FortiGate version you have downloaded in your system will be displayed in green color here. Select the FortiGate VM and click “Next”.

STEP 8
After you click Next, a confirmation message will be displayed. Click on Yes to install the appliance. The GNS3 will upload a copy of that file to the GNS3 VM.

STEP 9
after the previous step, a new window will appear then click Finish to complete the appliance addition. You will see the Default Username and Password.

Our next step would be initial configuration to get the GUI access as we have completed all the steps of FortiGate VM installation in GNS3.
STEP 10
Post these steps, you will see FortiGate Firewall in the GNS3 toolbar. Now, you can create topologies with the new FortiGate appliance. Drag and drop the appliance from the GNS3 Toolbar to the GNS3 Workspace.
When you will create your topology then you need to start the appliance: Right-click on the Device and click Start. 
To open a console to this device: Right-click on the FortiGate Device and click Console.
At the login prompt, type admin and press Enter.
The password area is blank by default and it may prompt immediately to change the password. You have to provide the password twice.

STEP 11
If you will connect the FortiGate Firewall with the DHCP server, then it will get the IP address details or you can configure the Firewall statically.

In my case, I configured it manually and set the IP address as 192.168.122.134 and it might be different in your case. Open Browser and enter IP in the URL bar.

We hope after reading this blog, it will be very easier for you to install the firewall in GNS3.

We also have written about the FortiGate Firewall and its use cases and about the FortiGate Firewall Installation in VMware Workstation.
