Now if the modem/router connected to the physical computer has a built in DHCP server use the following command to configure the router port to recieve IP address via DHCP.
Select and add the network interface of the physical computerĬonnect a router to this cloud using an ethernet link, open the console of the router and navigate to the interface which is connected to the cloud node.

Place a cloud node in your topology, right-click select configure and from the drop down list under the ethernet tab select “Local Area Connection” on Windows or “eth0” on Linux and click OK. Open GNS3 as an administrator (Windows) by right clicking it and selecting “Run as administrator” or as a root user (Linux) by using the sudo command. This is the simplest means of connecting GNS3 to the internet. In this scenario your physical machine is connected to a modem/router using a RJ45 cable and the ethernet port of your computer has a private IP address assigned manually or via DHCP. (Physical interface has a private IP address) Connecting GNS3 to the Internet – Scenario 1 Apart from making configuration changes to your operating system NAT has to be configured on the emulated router that connects to the internet. But if you are using a WiFi connection/Data card/a device that requires you to assign a public IP on the physical interface getting your lab to access the internet requires a few more commands in Linux or a few more clicks in Windows. If you just have an ADSL modem/router connected to the ethernet port of your physical machine having a private IP address it is very simple to get your lab to the internet. There are many ways to do this based on what internet connection you are using. Connecting GNS3 to the internet is just another step to bring your emulated network lab closer to real gear.
