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.

Ho acquistato un Cudy P4 AX3000 per utilizzare il servizio di tunneling con protocollo OpenVPN client. Dopo aver seguito la guida per la configurazione del servizio riuscendo a stabilire la connessione con il server OpenVPN non riesco a raggiungere i dispositivi LAN tramite Port forwarding. Come posso risolvere? Grazie mille
Wenn ich für WireGuard VPN die von der Fritz!Box erstellte Konfiguration lade, kann ich nicht mehr über den Browser auf den Cudy-Router P5 zugreifen. Auf der Fritz!Box wird die Verbindung zum P5-Router als grün bzw. ok angezeigt. Die SSID des P5-Routers ist immer noch sichtbar, so dass eine Verbindung noch möglich ist. Auch mit der Cudy-App kann ich nicht mehr auf den Router zugreifen. Was mache ich falsch?
