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.

“Hola, ¿hay alguna previsión de en algún momento incluir soporte de Tailscale?, concretamente en los modelos WR3600 y WR3600E que son de los que dispongo, para mí sería un punto muy a favor y espero que algún día lo implementen. Gracias y un saludo.”
hi to all,
i have a WR3600 V1.0, FW: 2.3.12-20250612-115717
and i am trying to set up a VPN, (openVPN client).
the status is connected, and it is working as VPN.
BUT, at system status >>> devices, whatever is the position for the VPN switch, all devices are ALWAYS through the VPN.
That means i cannot control which devices will have VPN and which not.
do you have any ideas to help me?
I have a cudy WR3600H with vpn wireguard installed and kill switch On. Vpn works great. But when i turn off the vpn from a connected device it also loses connectivity to the internet. When i turn completely off vpn all devices connect to internet.

Hi support team,
Do the WireGuard interface settings support dual-stack IPv4/IPv6?
