V2rayN Setup Guide: VLESS/Xray Configuration for Windows
V2rayN is the most popular Windows client for VLESS and VMess protocols. This guide walks you through installation, importing configs from clipboard, enabling TUN mode, and fixing common issues like the green tray icon.
V2rayN setup guide for Windows: import a VLESS Reality connection string, pick the right core (Xray, not V2Ray), enable TUN mode for full-device routing, and confirm you are seeing a Polish mobile carrier IP. Takes about 5 minutes from download to working Windows proxy client.
Download & Install V2rayN
V2rayN is an open-source Windows GUI for Xray and V2Ray cores. Get the latest release from github.com/2dust/v2rayN/releases β download the full package that includes the Xray core, not just the GUI installer. You need both files for VLESS Reality support.
Run the installer as administrator. After installation, V2rayN appears in your system tray. Right-click the tray icon to access all features.
Import VLESS Config from Clipboard
The fastest way to add a server is to import from clipboard. Copy your VLESS connection string (format: vless://UUID@host:port?...) then right-click the V2rayN tray icon β Servers β Import from Clipboard. No string yet? A Proxy Poland mobile proxy includes VLESS/Xray access, and you can test one free for 1 hour first.
After import, the server appears in the main window. Double-click to verify the configuration details: UUID, server address, port, and transport settings.
VLESS String Format
vless://UUID@proxyhost:443?encryption=none&security=reality&sni=example.com&fp=chrome&pbk=PUBLIC_KEY&sid=SHORT_ID&type=tcp&flow=xtls-rprx-vision#ProxyPolandCore Settings & TUN Mode
For system-wide proxy, enable TUN mode: open Core Settings (Ctrl+O) β TUN tab β Enable TUN. This routes all traffic through V2rayN, not just browser traffic.
In Core Settings, set 'Core Type' to Xray for VLESS Reality support. VMess and older configs work with V2Ray core but VLESS Reality requires Xray.
Proxy Poland provides dedicated 4G/5G mobile proxies with VLESS/Xray protocol support. Polish IP, IP change once per minute, 99.9% uptime target.
Understanding the Tray Icon Colors
V2rayN uses tray icon colors to show connection state: Red = disconnected/error, Yellow = connecting, Green = connected and routing traffic.
If the icon stays green but you cannot reach sites, check that the correct server is selected (bold in the list) and that the proxy mode is set to 'Global' or 'PAC' rather than 'Direct'.
Testing Your Connection
After connecting, check your IP at proxypoland.com/tools/proxy-checker or whatismyip.com. It should show a Polish mobile carrier IP from a CGNAT pool. Run a speed test: VLESS Reality on Proxy Poland modems typically hits 30-50 Mbps depending on your distance to the server.
Troubleshooting
Connection refused: Check firewall β Windows Defender may block V2rayN. Add an exception in Windows Security β Firewall β Allow an app. Also verify the server UUID and port are correct.
Slow speeds: Try switching the transport to XTLS-Vision flow in config. Ensure Xray core is selected, not V2Ray. For best performance with VLESS Reality, the server must support XTLS.

Frequently Asked Questions
V2rayN is the Windows client (N = PC), V2rayNG is the Android client (NG = Next Generation for mobile). Both support VLESS and VMess protocols but are separate applications for different platforms.
Copy the vless:// string to clipboard, then right-click the V2rayN system tray icon β Servers β Import from Clipboard. The server is added instantly without manual configuration.
Yes, VLESS Reality is sensitive to clock drift. If your system time is off by more than a few minutes, Reality handshake fails. Ensure Windows Time is synced: Settings β Time β Sync Now.
Green means V2rayN is active and routing traffic. However, green only confirms the client is running β it does not commitment all traffic goes through the proxy. Check the proxy mode (Global/PAC/Direct) to confirm routing.
Yes. Proxy Poland supports VLESS and Xray protocols on all proxy plans. You receive a VLESS connection string with your credentials. Import it directly from clipboard into V2rayN and connect.
V2RayN keeps profiles in guiNConfig.json inside its install directory (typically %USERPROFILE%\Downloads\v2rayN-Core or the folder you extracted to). Back up that file to migrate profiles to another machine. Subscription URLs auto-refresh from the source on the interval you set under Settings; manually imported profiles persist until you delete them.
Click the V2RayN tray icon, choose Servers > Import from QR code from screen. V2RayN scans your primary monitor, finds the QR code (display the URI from your phone or another window), and creates the profile automatically. If detection fails, fall back to clipboard import: copy the vless:// URI and choose Servers > Import from clipboard.
Green tray = active profile is running and proxy is up. Red = service stopped or profile failed to start. Right-click the tray icon and pick 'V2Ray-core information' to see the raw startup logs and any handshake errors. Common failures: wrong UUID (auth fail), wrong publicKey/shortId on Reality (TLS verification fail), wrong serverName (SNI mismatch). The log line shows which one tripped.
Right-click the tray icon and pick HTTP proxy > Set system proxy (forces all traffic), or HTTP proxy > PAC mode (uses a rule file to route only matching domains). PAC is preferable when you only want VLESS routing for specific hostnames; system proxy is simpler but routes everything. The local SOCKS5 port (default 10808) and HTTP port (default 10809) stay the same in both modes.
Yes β Settings > Common settings > 'Start on boot' adds V2RayN to Windows autostart. To also auto-activate the last-used profile, enable 'Auto-start last used server'. The tray icon appears at boot; the proxy ports become listenable within a few seconds. For headless server use without GUI, switch to v2ray-core directly or Xray-core with a config.json instead of the V2RayN GUI wrapper.
With the profile active, open a browser configured to use 127.0.0.1:10809 as HTTP proxy (or the SOCKS5 port). Visit ifconfig.me or whoer.net β the IP shown should match the VLESS server's egress, not your local ISP. Then run V2RayN's built-in 'Test current server (real delay)' from the right-click menu β it sends a TCP probe and reports milliseconds; under 200 ms is healthy.
Three usual causes: time skew on the local clock (Reality requires sync within a few seconds β fix with w32tm /resync on Windows), MTU issues on the upstream link (lower fragmentation MTU in profile to 1380), or carrier-side throttling on the egress mobile IP (rotate the proxy to refresh the carrier session). Check V2RayN logs for 'tls handshake' or 'context deadline' errors to narrow it down.
