ZeroTier

ZeroTier feature available since V4.2

ZeroTier is a software-based virtual private network (VPN) that enables secure, encrypted communications between devices over the internet. It creates a private, virtual network that allows devices to communicate as if they were on the same local network, regardless of their physical location or network topology. ZeroTier is designed to be easy to set up and use, and offers features such as end-to-end encryption, network segmentation, and network bridging capabilities.

The ZeroTier feature in GL.iNet router allow the router to join the ZeroTier virtual network, then you can access it remotely, even to its WAN or LAN resources.

Note: Because ZeroTier is based on WireGuard, it is not recommended to use the ZeroTier feature with the OpenVPN Client or WireGuard Client at the same time, as there may be bugs.

Note: This feature is currently in beta, and may have some bugs.

Setup

The following is an example of the GL-MT2500.

1. Create your first ZeroTier network

   Refer to ZeroTier's official Getting Started documentation to create a ZeroTier account and network. Remember to take note of the Network ID, which is a 16-digit combination of letters and numbers, as it will be needed when connecting other devices later on.

   

2. Enable ZeroTier on GL.iNet router

   Access router's web Admin Panel, on the left side -> APPLICATIONS -> ZeroTier

   Enable the toggle button, fill in the Network ID in the first step then click Apply.

   

   After a while the interface will indicate that authorization is required, which we will handle in the next step.

   To facilitate testing, add another device (such as a computer or phone) to the ZeroTier network following the instructions in this document.

3. Authorize your device on your network

   

   To authorize your device on your network, click on the ZeroTier Central icon and navigate to the Members section of the settings for your network on the ZeroTier website.

   

   Locate the new device and click on the Auth checkbox to authorize it. Customize the name of the device if desired.

   Note: The device's Address should be displayed on the ZeroTier page of the router, but this feature may be added in future versions. To confirm the current Address of the ZeroTier on your router, SSH into the router and use the "zerotier-cli info" command.

   

   After a short while, ZeroTier will assign a Managed IP to the device. Take note of this IP address as it will be used in the testing step.

Test connectivity

On another device that is also on the same ZeroTier network, use a web browser to access the router's web Admin Panel using the Managed IP obtained in the previous step.

Normally, you will be able to access the web Admin Panel of the router. You can also use the ping command mentioned in the official documentation to test it.

Allow Remote Access WAN

If this option is enabled, the resources on the WAN side of the device will be allowed to be accessed via the ZeroTier virtual network.

For example, as shown below, if this function is enabled, you can access GL-AXT1800 by its IP(192.168.29.1) from leo-phone, because GL-AX1800 is connected to the WAN port of GL-MT2500, which is the upper layer device of GL-MT2500.

The operation steps are as follows.

1. Enable Allow Remote Access WAN.

   

   It will prompt you to set up routing rules.

   

2. Go to the my.zerotier.com or click on ZeroTier Central in the image above, find the Advanced sector of settings panel. Fill in the route (Destination and Via) requested in the previous step. Click Submit.

   

   After adding.

   

3. Now you can access GL-AXT1800 by its IP(192.168.29.1) on other machines. You can actually access the devices at 192.168.29.0/24.

   

Allow Remote Access LAN

If this option is enabled, the resources inside the device LAN will be allowed to be accessed via the ZeroTier virtual network.

For example, as show below, if this function is enabled, you can SSH to Ubuntu by its IP(192.168.8.110) from leo-phone, because Ubuntu is connected to the LAN port of GL-MT2500, which is the lower layer device of GL-MT2500.

The operation steps are as follows.

1. Enable Allow Remote Access LAN.

   

   It will prompt you to set up routing rules.

   

2. Go to the my.zerotier.com or click on ZeroTier Central in the image above, find the Advanced sector of settings panel. Fill in the route (Destination and Via) requested in the previous step. Click Submit.

   

   After adding.

   

3. Now you can ping or SSH the by its IP(192.168.8.110) on other devices. You can actually access the devices at 192.168.8.0/24.
