A flexible and highly adaptable network topology simulator application that you can rely on to set up networks without needing any expensive hardware
What's new in GNS3 2.2.0 Beta 2:
- GUI:
- Fix wrong aligment of symbols in saved/exported projects. Fixes #2800
- Replace urllib.request by Qt implementation for local server synchronous check. Fixes #2793
- Support snapshots for portable projects. Fixes #2792
If you are interested in computers and hardware or you like to experiment with connections between routers or switches, then you are bound to appreciate the feature set of GNS3, as it enables you to set up topologies of routers (like IOS and JunOS), firewalls (such as (ASA or PIX) and hosts without risking to break down your equipment.
GNS3 supports several types of routers and switches, so it can help you study for certification exams such as Cisco CCNA, CCNP, CCIP, CCSP, CCVP and CCIE, Juniper JNCIA, JNCIS or JNCIE, while being equally useful to network engineers or admins.
Once you install the application, you can start creating your own project from scratch and add the objects you need by dragging and dropping them from the devices panel onto the dedicated area.
Next, you can establish relations between them as you see fit - when you try to create a faulty connection, GNS3 displays a warning message so you can correct your mistake. Due to this, you can rest assured that the topology you come up with can be applied on real devices without any glitches.
You can adjust the attributes of each of your objects to helps them match your exact requirements, and test the configuration every step of the way by running a simulation. You can even customize the display within the main window of GNS3 by hiding layers, interface labels or hostnames.
In a nutshell, if you are studying for a Cisco or Juniper certification exam, or you want to test a certain topology you created, you will surely appreciate the functions of GNS3. And since it is a freeware utility, you can just go ahead and discover its features yourself.

The blog is for the new GNS3 VM (Virtual Machine) users on Windows 7/8/10.
What is gns3?
It’s a graphical network simulator that allows you to design complex network topologies, where you can run different devices (irrespective of vendors) like cisco, juniper, chCheckpointFortinet, PFSense etc.
New features:
Gns3 has introduced VM which is referred to as gns3 VM and makes it easier to configure and install network devices as per the users wish without interrupting the host os (windows)
è The VM is introduced to overcome the shortcomings of hosts OS
è The VM is powered by Ubuntu
è The VM is installed on the virtual box, VMware workstation, KVM, hypervisor
Requirements:
è Core i3/i5/i7 Processor with 8/16 Gb ram
è Windows 7/10 operating system (Windows 7 would be ideal)
è VMware workstation/virtual box (VMWare workstation would be ideal)
Installation:
è You can download VMware Workstation
è You can download gns3 VMhttps://github.com/GNS3/gns3-gui/releases/download/v1.5.4/GNS3.VM.VMware.ESXI.1.5.4.zip
è You can download gns3 application GUI
è Please Install the VMWare workstation then import gns3 VM Into VMware and allocate enough memory 8 GB would be ideal and click start
è Now install gns3 GUI after installation, disable windows firewall to allow GUI to get connected to VM.
Configuration:
è After starting VM Please enter default username and password
1.User Name: root/gns3
2.Password: gns3vm/gns3
è You can configure different port and location of file saving in gn3 by navigating to Preferences in the edit menu.
è Let’s define few setting briefly General preferences are the options defines users project storing location.
è Server preferences allow user to set GNS3 VM application and Ports.
è Packet Capture preferences specify location of packet capture.
è VPC for virtual private cloud path or location.
è Dynamips->IOS Routers to install IOS Devices.
è IOS on Unix->IOU Devices for old version devices installed on Unix/Linux or Linux images
è QEMU->Qemu VM’S for Cisco ASA and other firewalls.
è Virtual Box, VMWare for type of application we are using to host GNS3 VM
Installing and Configuring Devices:
The GNS3 VM has a new feature called “New Appliance Templet” where we can import images of devices such as routers, firewalls etc.
How To Install Gns3
You can download this temple from GNS3 Marketplace.
