A Simple Guide to VPNs and How to Set Them Up on Ruijie Cloud

In today’s digital world, VPNs (Virtual Private Networks) have become essential tools for internet users. A VPN creates a secure, encrypted connection over unsecured networks (like public Wi-Fi), allowing you to access restricted resources, protect your online privacy, and bypass geographic limits. Let’s break down the basics of VPNs and show you how to set one up easily using Ruijie Cloud.

What is a VPN?

A VPN acts like a secure tunnel between your device and the internet. It hides your online activity from hackers, ISPs, or anyone trying to monitor your connection. There are two main types of VPNs:

Site-to-Site VPN: Connects entire networks (e.g., a company’s headquarters and branch offices) over the internet.

Client-to-Site VPN: Lets individual devices (like laptops or phones) securely access a remote network (e.g., a corporate intranet).

Common VPN Types

1. Site-to-Site VPN

This type links multiple physical networks securely. For example, it lets a company’s offices share data safely over the internet.

Key Protocol:

• IPSec: IPsec is a network protocol used for the encryption of IP traffic. IPsec is frequently used as the secure communication protocol for business VPNs, most commonly with a tunneling protocol like L2TP. IPsec is supported on many operating systems and device types, including embedded devices and network routers.

💡 Best for: Businesses needing strong security and flexibility and where the performance requirements are not particularly high.

2. Client-to-Site VPN

This type connects single devices to a remote network. Popular protocols include:

OpenVPN

• Uses SSL/TLS encryption and supports AES (a high-strength encryption standard).

• Works on both UDP and TCP, making it adaptable to different networks.

💡 Best for: Privacy-focused users or accessing highly restricted content.

PPTP

• A basic tunneling protocol with simple encryption.

💡 Best for: Casual privacy needs or low-restriction content access.

L2TP

• Often paired with IPSec for extra security. Encrypts data at the data-link layer.

💡 Best for: Businesses needing secure remote access to internal resources.
