ZeroTier connects your devices with each connect two devices over ZeroTier. We'll use ping to test the connection. Any two devices that can run ZeroTier will do laptop, phone, virtual machine, etc… Both devices can be at the same location, on the same physical network. If you move one to a cafe or to your office, it should still just rough outline isCreate a ZeroTier networkJoin the network from two devicesping one device from the other over the ZeroTier networkThis should take about 5 PreviewHere is a summary of the results of this tutorial, if you're a networking this doesn't mean anything to you, that's OK. We'll get zerotier network you join creates a network interface on your device. It's like adding another Ethernet port to your your first ZeroTier networkCreate an accountnoteIt's free, no credit card is required. Go to and create an a networkMake sure you're on the "Networks" tab of Click the Create A Network creates a virtual network with a random ID and a random name. We got "fervent_smathers" and d5e04297a16fa690 here. Click anywhere on the network to go to the details page for this the Network Settings panel We don't need to change any settings, but we can change the name of the network to personalize "fervent_smathers" to "my cool network" or whatever you like. Collapse the Settings panel. Click on the word "Settings" at the top of the don't need to change any other the Network Members panelIt should say "No devices have joined this network".Leave this browser tab open. We'll look at it again the ZeroTier appDownload and install ZeroTierFor mobile devices, use the app to in a different tab of your the installerThe ZeroTier client should now running on your your first ZeroTier networkWe need to tell the client to "join" the virtual network we just the Network ID of the network from This is the long number that looks like like d5e04297a16fa690Paste the Network ID into the "join" command on your deviceOn macOS and Windows, there is a menubar/tray app. Select "join" from the menu. macOSWindowsCommand LineMobile noteEvery running instance of ZeroTier has a unique address. It's the 10 digit "Address" in the app, or zerotier-cli info addresses are a very secure method of unique your device on your networkAt this point, your client should say "Access Denied." A device can't talk on your network unless you allow it, even if someone discovers the network's Authorize your deviceGo to the Members panel that we left open on node that just "joined" should appear "Address" should match the address in your client. Click the "Auth?" check box for it. Give it a name. Type something like "laptop" or "bob" into the short name input. Confirm authorizationBack on your computer, your client should now say "OK" instead of "ACCESS DENIED" and it should show your custom "my cool network" Now you have 1 member on your network. A network with 1 member can't do much. Repeat with another deviceWe need to have 2 devices connected to the same ZeroTier the join and authorize steps with your second connectivityNow you have two authorized nodes on your network. They should be able to talk over ZeroTier. Your Network Members section should look something like thisThe "Managed IPs" will be different on your going to test with ping. It's the only program that we can think of that exists by default on every operating system. This is a command line program, but don't worry You can do it. Gotcha Windows blocks pingWindows by default doesn't respond to pings. If you try to ping a Windows computer from a different computer, it won't work. You can enable to enable ping on WindowsSearch for Windows Firewall in the Start Menu, and click to open Advanced Settings on the the left pane of the resulting window, click Inbound the right pane, find the rules titled File and Printer Sharing Echo Request - ICMPv4-In.Right-click each rule and choose Enable is a tutorial by MicrosoftOpen the command lineOpen the command line on your computermacOSWindowsLinuxMobileFind the ZeroTier IP Addresses of your devicesTry the ping commandBack in the Command Line / Terminal that you just openedtype ping -c 5 $ZEROTIER_IP_ADDRESS into your command line. A successful pingTry it with both ZeroTier Managed addresses on your of them is the same device you're on, so you're pinging yourself. Pinging the other device might be a little more something goes wrong you might see something likeor There may just be a typo in the IP address. Double check that your device is authorized at us on the discussion forum and see the troubleshooting section if you get doesn't accomplish anything, but it does tell us ZeroTier is working.

Make sure they don't use the same subnet! You can have a home network, a friends network, and a work network, for example. They don't all need to be networks that you've created.
