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.

I have WR3000S. I would like to setup either:
1. Open VPN with Certificate Authentication for Site to Site (server to server) tunnel not mobile client tunnel (password authentication)
2. IPSec with multiple phase 2 (remote network) configurations.
Please let me know if this can be done.
Right now, client cannot access all tunnels.
Hi,
I have a Cudy R700 configured as a WireGuard client with side-to-side access enabled. Access from the Cudy to the VPN server is working perfectly. However, I am unable to ping the Cudy R700 from the VPN server.
I would like to use the Cudy R700 as a WireGuard client and provide access to its local LAN from all other VPN clients.
Could you help me resolve this issue?
Hello, I have a TR1200 router that I need to configure as a WireGuard VPN client. What are the steps to follow to ensure it provides VPN communication via Wi-Fi and the LAN port? The TR1200 is configured as a router and assigns IP addresses in the range of 172.16.181.10 to 30, while the VPN client is configured with the address 192.168.10.4. How should this configuration be applied?
