![]() ![]() I also needed to follow gateway, 10.4.1.1. I’m going to make it 10.4.1.101, so that you can tell something has happened. So you can see if you type this, it would make a change. Netsh int ip set address “Loopback” static In this case because it’s a loopback, I will select that. If you’re doing this from the Command prompt, you can add: Then, it only shows me exactly the loopback interface. If I don’t want to see the whole thing scroll by, I have to scroll back up. I’ll hit the up arrow to bring up my latest command and add “ Loopback”. ![]() If you miss that command, and by the way you’ll notice that because it has a name, Loopback, I can slightly modify my command. That’s the address I want to put on that router. Notice here in this output, I have a default gateway set of 10.4.1.1. ![]() But I needed its information because I put a router in there. I put that on there also before this started, but you can put the IP address on your loopback interface. This is one of the cools things you can do with the netsh context. I want to look at my configuration so I’ll type netsh int ip show address. I’ll go ahead and launch this as administrator. In the meantime, let’s see what’s going in the Cloud 1. I want to grab the Console connection because I want to able to see what’s going on this router. Let it boot up and then I’m going to right-click on the router. Notice that my little dot turns to green. I’ll click the little green triangle and get it running. Now I need my connectors, so I’ll pick the Loopback for the cloud.Ĭonnect it to the Router using FastEthernet 0/0. I’m going to bring in another router by dragging it into my scenario. I need one other thing at least to connect to it. If I click this drop down, remember I named my loopback? I’ll select Loopback. ![]() I have my cloud.īefore I can connect to it, I have to configure. What it’s going to be, it’s the actual laptop machine that I’m connecting to. I’m going to change the symbol to a Computer. You can right-click on this and change the shape. What I want to do now is click on My Devices. You want to right click on that and run it as administrator.Ī lot of stuff will not work correctly inside GNS3 if you don’t do that. When you launch GNS3, I could double click this and it would launch. If you don’t reboot your machine, you’re not going to have good success. Once you do that, very important, reboot your machine before you continue. Now, it’s Microsoft KM‑TEST loopback adapter. If you’ve done this before, there was a Microsoft loopback adapter. This is a little bit weird or different from what you’re used to. You could have hit the letter N, it will get you there faster. I want Networks, so scroll down to Network. And then select the option Install the hardware that I manually select from a list (Advanced) It brings up the wizard, and I’ll click next. Right click on it and select Add Legacy Hardware. It used to be Microsoft loopback adapter.Īs I said, I already have one but let me show you if I didn’t, if this was a brand‑new, clean install, what I would do is come up to the top where it says MJ-Len-LPTP. Notice this Microsoft KM‑TEST Loopback Adapter which by the way Microsoft has slightly changed the wording. What you want to do is scroll down to your network adapters. What I need to do is I need to add a loopback adapter into my machine. In this case, it even goes a step further because I want to take my GNS3 environment connected to a real network.įirst thing I have to do, and I’ll show you the steps. You can do far more testing with a real box. This allows for numerous options of connectivity, better than taking a router and connecting it as an IP Endpoint to generate pings. In this post, I want to show you how to connect GNS3 to a valid external host. In a previous post, I showed how to connect GNS3 to an Oracle VM VirtualBox.
