Click on the “Restore” symbol in the upper-right corner of Firefox, to take it out of the fullscreen view: Starting up the Webterm container (the NAT node will automatically be running from the moment it’s added to a topology) and opening its console will result in a VNC window appearing. That symbol causes the system to not read those lines, and are commonly used to add comments to code, which should not be processed) (uncomment means removing the ‘#’ symbol at the front of those lines. To configure this container to use DHCP, you uncomment the two lines shown in the below image, and click Save:

You enable DHCP or manually configure static IP assignment to docker container like Webterm, by right-clicking on it while it’s shutdown, and then select “Edit config”:Ī window will open, showing this container’s /etc/network/interfaces file: To allow more than one topology node to have access to the internet, it will be necessary to connect a switch or router to the NAT node, and then connect the topology nodes to the other device.įor simplicity, the built-in ethernet switch will be connected to the NAT node, and the Webterm container will be connected to the switch: The NAT node has a single interface named nat0: Next, the Webterm docker container will also be added to the workspace: The NAT node will appear in the workspace: This article will use the Webterm docker container for testing internet connectivity, so the server type needs to be set to GNS3 VM, as this is being done on a Win10 workstation: You will be prompted to specify the server type you want to use, to run the NAT node. To add the NAT node to a topology, drag and drop it into the workspace. It’s located in the End devices category: Libvirt is necessary, to create a virbr0 interface for this node to function.īy default, the NAT node runs a DHCP server with a predefined pool in the 192.168.122.0/24 range. The NAT node requires either the GNS3 VM, or a Linux computer with libvirt installed. It’s also much simpler to use than the preexisting Cloud node.

It’s useful when you need to download things from the internet, like packages, if nodes need to perform license check, etc…). If that is required, then the Cloud node should be used. Your topology will not be directly accessible from the internet or local LAN, when using the NAT node.
