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

@Dear apostolos,
1. Please update the latest firmware of your router first. You can download the firmware on the website below.
https://www.cudy.com/pages/download-center/search
2. Then please check the instruction about the Nord VPN, it is almost the same.
3. If the problem remains, please offer me some information.
The screenshot of the VPN settings page.
Download the Diagnosis bin file in “Diagnostic Tools”→“Diagnosis”→“GO”→“Download”, and send the file to me.
The VPN config file.
I will check and try to find a solution.

@Dear Konstantinos,
Sorry to tell you that there is no firmware of WR1500 that supports OpenVPN. We have plan to add it in future.
“Is there an older firmware of 1500 that includes openvpn client ? or there is only wireguard solution ? thanks”

@Alex,
For now, the Wireguard VPN performance of WR1500 is not good. I think the performance 20Mbps is normal of WR1500. We will provide your feedback to our R&D team to optimize this in future.
“Wireguard.”
