This tutorial will show you how to setup a VPN tunnel between your Cudy machine and any other computer. ZeroTier is one of the easiest VPN services to configure and it's completely free for up to 50 devices. The entire process, from start to finish, should only take a few minutes.
1. Create ZeroTier Accounts
2. Create a Network
- After you've logged in to ZeroTier, navigate to the Networks tab
- Click Create New Network and your Network ID will be visible in the interface

3. Choose Public or Private Access
There are two ways to manage access: Public or Private
Public Network: Anyone with the Network ID can connect. This is the easiest option but is slightly less secure.
- Click on the Network in the ZeroTier interface
- Under Access Control, select the Public Network option:

Private Network: All machines must be approved through the ZeroTier interface before they can connect. This is the default option and is more secure.
- When machines join the Network (see Step 4), they will need to be approved under the Members section. Just check the box under the Auth? column to approve each machine:
4. Setup Cudy Router
- A. Open a web browser and Login to http://cudy.net/ or http://192.168.10.1/
- B. Go to General Settings -> VPN to set Zerotier, choose Zerotier master and input the Zerotier Network ID. Then click Save and Apply.

- C. If you configure your network as Private network,need to check the box under the Auth? column to approve Cudy Router again.

- D. Add Routes for Cudy router.

5. Install ZeroTier App
Download and install the ZeroTier App on all machines you would like to connect.
6. Join machines to network
When the ZeroTier app is running, click Join Network
Enter the Network ID from Step 2 and click Join. If you created a Public Network, you should now be connected. If you created a Private Network, you will need to approve each machine in the ZeroTier interface (see Step 2).
7. Verify connectivity
You can check to see if you've successfully connected by clicking Show Network on the ZeroTier app. The Status should show OK and the Connected box should be checked. You can also try pinging a private IP address of another machine to verify the connection.
8. Remote Access
Then you can remote access cudy router use 192.168.10.1 (192.168.192.118) or the subnet 192.168.10.xxx.

Hi Support,
Will be there a future upgrade to enable Zerotier on the LT 300 V2 ? I recently purchased this device as a 4G backup as I thought it has the Zerotier option for VPN but unfortunately it didn’t and did not see anywhere if this option will be available in the future. Many 4G mobile ISP’s use CGNAT and makes using the device as a Wireguard /OpenVPN server useless. Zerotier would fix this , at the moment I have an ISP that is not using CGNAT and can use Wireguard server with DDNS as I don’t have a fixed IP , but the day I switch over to another 4G ISP provider with CGNAT Wireguard/OpenVPN server will not work……If no implementation is plannend for this device I’m going to return it sadly….
