V2Ray

What is V2Ray?

V2Ray is a very powerful and privacy-enhancing proxy tool. It supports multiple protocols, can bypass the censorship of many countries, and traffic is fully encrypted, securing your internet use without restrictions.

Note: V2Ray itself is only a protocol framework but is not a provider of servers. You may want to either set up your server or subscribe to one, often referred to as "机场" in Chinese .

Common Protocols:

  • VLESS: Lightweight and generally better for servers.
  • VMESS: can be configured with advanced features to bypass highly strict censorship.

The most popular config is: VLESS + CDN + WS + TLS.

Terms Explanation

Term Meaning
VLESS A protocol used in V2Ray configurations.
WS WebSocket, an upgraded HTTP protocol supporting real-time data syncing.
TLS Encrypts data to not be visible to firewalls.
CDN Content Delivery Network; puts content closer to users for speed and makes blocking servers much more difficult.

Setup: VLESS + CDN + WS + TLS

Requirements

  • A domain name with cloudflare
  • A Linux VPS with port forwarding for 443 and a random port (Other web hosting services like Render or Koyeb will also do; they provide a domain and CDN in most cases.)
  • Basic command line skills
  • Root
