INTRODUCTION
A Virtual Private Network (VPN) is used to create an encrypted connection tunnel, enabling users to
exchange data across shared or public networks while acting as clients connected to a private network.
The benefit of using a VPN is to ensure the appropriate level of security to connected systems when the
underlying network infrastructure alone cannot provide it. The most common types of VPNs are remote-
access VPNs and site-to-site VPNs.

The VPN security model provides:
✓ Client authentication to forbid any unauthorized user from accessing the VPN network.
✓ Encryption, that will prevent man in middle attacks and eavesdropping on the network traffic.
✓ Data integrity to maintain the consistency, and trustworthiness of the messages exchanged.
The purpose of this guide is to underline VPN client/server feature on Grandstream GWN7000 Router and
use this feature to implement Site-to-Site VPN using OpenVPN
