GNS3 provides various customization options. In principle, you can also configure the virtual routers to use an IP address from your provider's DHCP server. If the configuration is correct, ping can query the desired system. You can now use ping to check the accessibility of an external system from the console. Log into the Internet appliance at the console by entering gns3Īs the username and password. Use the Linkįunction to establish a connection between the two routers and one between the Internet device and R1 ( Figure 2).įigure 2: The Internet template connects the virtual with the real network. You will also need two routers, which are automatically labeled R1 and R2 by GNS3 ( Figure 1). In the next step, drag the Internet device into the workspace. After the installation, the Internet router is available from the toolbar in the Devices category. You have to agree explicitly to its installation. , determine the image file available on the VM. In the following steps, you will again be accompanied by a wizard, which now wants to know whether you want to use the VM or another server type. After selecting the import file, GNS3 presents the Add Appliance dialog, which lists important appliance-specific data, such as the category (Router), the name (Internet), the manufacturer (GNS3), and the architecture (i386). Ī good idea is to create your own project for this module and then import the module into GNS3 with the File | Import Appliance If the associated template is not available from the Marketplace, you can alternatively get it online. , and it comes from the GNS3 development team. The procedure differs fundamentally depending on whether you are working with a GNS3 VM or with a local server installation it is far easier with the VM.įor the GNS3 VM, you need the Internet appliance from the Appliance category of the GNS3 Marketplace. Dynamips lets you connect virtual routers to physical network interfaces, so GNS3 can also connect virtual networks to physical hosts.
