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.

Dear Freddy,
Thank you for contacting Cudy support team.
Sorry to tell you that No, the Cudy routers don’t support VPN cascading function now.
“Is it possible to achieve VPN cascading using a TR3000.
The configuration is:
1. A VPN server (VPN A) is set up at Site A.
2. A TR3000 is situated at Site B where the device have the VPN client enabled to connect to VPN A and VPN server (VPN B) is also enabled.
3. At Site C, client devices have VPN clients connected to VPN B.
All traffic generated by client devices at Site C is encrypted using VPN B protocol goes to TR3000. The TR3000 decrypts traffic from the clients by VPN B server and encrypts it again using VPN A protocol before sending it to VPN A. This is the solve the problem where devices at Site C do not have reliable routes to Site A directly.”

“Hello, I have a problem with Wireguard site to site vpn. It’s connecting to destination router, however I cannot access local subnet from remote subnet. It’s working the other way. I also spotted that route 0.0.0.0/0 is injected to routing table despite the fact I only specified remote subnets as destination for vpn tunnel policy. What is the solution as I cannot access ssh and check and correct vpn settings manually?”
