A VPN client is a terminal device or software used to establish a secure connection between a user and a VPN server.
What is VPN?
VPN (Virtual Private Network) helps you access internet resources remotely, securely, and privately with tunneling technology. The VPN encrypts your personal information and hides your IP address from the public when you use the internet. To the users of the VPN, it will look like the computers were directly connected to each other.
Common Network Topology:
Here we take WR2100 as a demonstration.
Step 1: Open a web browser and go to http://cudy.net or http://192.168.10.1.
For details, please refer to How to log into the web interface of Cudy Router?
Step 2: Click on General Settings->VPN and enable VPN.
Default Rule: Allow all devices or Ban all devices to use VPN.
To specify the device, click on System Status-> Devices->VPN to enable or disable it.
Site-to-Site: Allow the devices in two sites to communicate with each other.
VPN Policy:
Disable: No additional setting.
VPN kill switch: Turn off the Internet connectivity when the VPN connection is lost.
Domain: Specify which domains go through the VPN and which don't
Remote Subnet: Specify what subnets go through the VPN and which don't
Step 3: In the Protocol list, select the one you need and enter the VPN information provided by your VPN provider.
• PPTP VPN
Enter the VPN server address (for example, 113.92.73.163) and the VPN Username and password provided by your VPN provider.
• L2TP VPN
Enter the VPN server address (for example 113.92.73.163), VPN username and password, and pre-shared key provided by your VPN provider.
If your VPN provider also provides you the tunnel IP which binds with the account, you can enable the Use custom tunnel IP option.
• OpenVPN
Click on Browser to import the configuration file provided by your VPN provider.
• WireGuard VPN
Click on Browser to import the configuration file provided by your VPN provider.
The Interface and Peer will synchronize automatically from your VPN Provider's CONF File.
• ZeroTier Slave
Type in the ZeroTier Network ID and Gateway provided by the ZeroTier Master. The Gateway can be found on VPN Status part.

@yilmar londoño,
Dear Customer.
Thank you for contacting Cudy support team.
Please check if the Cellular IP address is a public IP address? As shown nelow. If the public IP address is the same as the IP Address? If not the same, the Cellular IP address is not a public IP address, then you can’t access the router from the internet. You can try to ask the ISP if they can offer you a public IP address.
Hello, I have two cudy lt400 routers, I need to connect them through wireguard, the server router is connected through a 4g chip, when creating the client and the server, the client never connects to the server, I ping the server’s public IP from another network, the ping does not respond, could this be the problem?

Dear customer,
Thank you for contacting Cudy support team.
1. What is the speed when enable the VPN function. Is it possible to use the wireguard VPN which will have faster speed?
2. We have plan to add it to the Cudy APP, please wait for the update.
“Hello, I bought a cudy LT700 4G/WiFi openvpn router. Everything works good after configuring open VPN but 2 issues.
First issue: Once VPN is enabled the speed is reduced by 80% which is not good. I won’t blame the VPN because I can connect via tplink openvpn router or software con and the performance is reduced by only 20%.. so what happens with cudy lL700, why I am seeing 80% performance loss?
Second issue: the cudy app do not have “VPN” option, I have to use the browser to enable or disable VPN? What should I do have the VPN option in the app?”

Hello,
I would appreciate it if you could please send me a response to my email. My question is similar to that of Francesco. My router is AX3000S.
Thank you for your attention.
