You can enable the grid if you want things to look tidy. Essentially, this is very similar to creating a flowchart. To connect them to one another, add a link. Drag a symbol from the sidebar to the workspace to add a new interface. It has the following options: routers, switches, end devices, security devices, and links. The sidebar on the left displays the nodes (or interfaces) that you can add to the workspace in the middle. Before you begin, you will need to start a new project (to save your work). Give it a name, select where to save it and many of the options on the GNS3 client interface will become usable. The program won't function correctly until a working server is detected. You'll see the local server displayed on the right pane. You will see a dialog box and you need to wait for it to close which may take a moment. Run the client program and wait for it to connect to the server. Interface tour + Creating a virtual network Hit the import button and wait for it to complete the process. Click on open again, and choose the folder where you would like to import the virtual machine to. VMWare Player users can click on Player > Open and browse to the folder where the GNS3 VM.ova file is located. Extract the archive which the VM image comes in to a folder. Since I use VMWare Workstation Player, I used the GNS3 package which was available for it. It's available for Virtual Box, VMWare Workstatiom, VMWare Pro, ESXi anbd HyperV. This is basically an Ubuntu virtual machine. Note: However, pay attention to the final step of the installation, because there is one more optional program (Solarwinds toolset) that you can download. Npcap is required for your network cards to communicate. But then I noticed that the GNS3 client integrates these tools and you can use them directly from within the program's interface. You can uncheck any of these, though I would suggest you install them unless you know that you don't require some of them I did so for the purpose of reviewing them. The installer has quite a few third-party network tools that are pre-selected for installation. ![]() Windows users should download the all-in-one (EXE) from GitHub or SourceForge. ![]() The GNS3 client is what you use for controlling the virtual machine server and simulating the network. Installing the GNS3 client on Windows, Mac, and Linux You can download the program and the server VM from the GitHub or SourceForge pages without registration. Note: If you want to download GNS3 from the official website, you will need to register for an account, and that requires a lot of personal information. The tool consists of two parts, a virtual machine that acts as a server and a client program that you use to interact with the server and access all of GNS3's features. Now, power on the SonicWall Firewall to get started! You can get below the screen while the SonicWall Firewall will get booting.This open source tool can be useful for setting up a local network in an office or other environments, and also for troubleshooting purposes. SonicWall NSv200 can support maximum 6 GB of RAM. Note: 2 CPU Cores and 4 GB RAM is minimum requirement for the SonicWall Firewall. The VMNet8 interfaces, allows SonicWall to communicate with the Internet and also provide the DHCP IP assignment. As you already know, SonicWall has preconfigured with X0, X1 & X2 interfaces. In my case, I’m giving 6GB RAM, 2 Processors, and 4 different virtual network interfaces (VMNet1, VMNet8 & VMNet3). After the successful completion of this process, just modify the assigned virtual network interfaces, memory, and processor. This process will take some time, so have patience. Select the ova file you have download from the support portal. Just open the VMWare Workstation and go to Files > Open (Ctrl+O). Now time to deploy the SonicWall virtual firewall in VMWare Workstation. Step 4: Deploying the SonicWall VM Image in VMWare Workstation For example, I am going to use 192.168.100.0/24 for the vmnet1 interface. After that, you have to provide the IP address. Click on the Add Network and make your virtual interface host only. ![]() Ubuntu, Mint, etc.) you can type the below command to open Virtual Network Editor. So, click on Windows Start Button and search for Virtual Network Editor. By default, there are only two virtual network interfaces, i.e., VMNet1 and VMNet8. Now, it’s time to configure your Virtual Network Adaptors as per your requirements. Step 3: Configuring your Virtual Network Interfaces for SonicWall Firewall
