Welcome to the first blog post in this new series on GNS3 in Azure. The first part of this series will cover how to setup GNS3 on Azure. I’ll share with you what works and what doesn’t so that you don’t have to waste your time finding out. I’ll then cover how to add appliances to GNS3 specifically using the Sophos network security appliances (the Sophos XG firewall and the Sophos UTM). I’ll then conclude by covering how to get internet connectivity working from within your lab environment.

Jan 31, 2013 Open GNS3 by right clicking it and choosing “Run as administrator”, insert a cloud node into the topology, right-click select configure Add the loopback adapter from the configure dialog box of the cloud node Add a router to the topology, connect one of its ethernet ports to the cloud and start the router.

  1. Insert a cloud (C1) and at the NIO UDP tab within cloud add a currently un used port for local and listening port say 40000 and 50000 respectively. And connect this C1 to R7. In the cloud that's already connected to R30 (I'll call it C2) add an NIO UDP with the local and listening port 50000 and 40000 respectively and reconnect it to this NIO.
  2. Running GNS3 from the cloud!!! Using Amazon EC2 server. Step by step instructioninstalling gns3# - Run apt-get update$ sudo apt-get update # - Install GNS3.

For those that may not be aware, GNS3 is a great application that is used by hundreds of thousands of network engineers worldwide to emulate, configure, test and troubleshoot virtual and real networks (and hundreds of thousands is not an exxageration). It was originally developed by a guy named Jeremy Grossman, who originally created the application to help him to study for his CCNP exam.


On a personal level, GNS3 really helped me to develop my computer networking skills and I’ve used it to better understand a many networking protocols and concepts especially in my earlier days in IT. I’ve built complex and fully automated lab environments based on GNS3 in the past and I still use those environments till today but sadly as I moved around to different roles, I’ve not had the chance to redesign the earlier environments on the latest version of GNS3 until now. Which is where this series come in – As I’m getting rid of most of my physical servers that I used to use for testing and relying mainly on my Azure test environments, I thought I’ll share the things that I’ve learned more recently with you around setting up a GNS3 lab environment on Azure.
