Prerequisites

  • An overseas VPS with an un-blocked IP; Debian / Ubuntu recommended.
  • No domain needed — that's REALITY's advantage.

A one-click script is easiest

The community has mature Xray install scripts that install the core, generate a UUID and key pair, and set up REALITY. Run it, choose VLESS + REALITY, and note the UUID, publicKey, shortId and port it prints.

Key parameters

  • dest / SNI: a major TLS 1.3 site that's reachable on your route.
  • Open the matching port in the VPS firewall.

Import to the client

The script usually prints a vless:// share link or QR — copy it into v2rayN with Ctrl+V. If it won't connect, first check the server's time sync and the port.
