This guide explains how to configure v2rayN on a Windows PC, from installing the client and importing nodes to enabling a proxy. It also covers how your exit IP, DNS, and browser settings can affect your connection. Follow the steps in order: first make sure you can connect, then troubleshoot any sites that won’t load. Menu names may vary slightly between versions.
1. Install the client and prepare your nodes
Download a stable release for your version of Windows and processor architecture from the Releases page of the official v2rayN GitHub project. Extract it to a permanent folder and run the main program; don’t launch it directly from the archive. If you’re prompted to install a runtime, follow the official instructions for your version. Don’t download DLL files from third-party sites.
The client itself does not provide usable connections, so you’ll also need a node sharing link or subscription URL. Common links begin with vless://, vmess://, or trojan://. Subscription URLs are usually HTTPS links and may contain access credentials. Don’t share your subscription URL or screenshots that show your full credentials. If you use free nodes, check their source and expiration date.
2. Import nodes and enable the system proxy
- Copy the full node sharing link. In the client, open the “Servers” menu or a similar menu and choose the option to import from the clipboard. Make sure the node appears in the list and no format error is shown.
- If you have a subscription URL, open “Subscription Group Settings,” add a group, enter the URL, and save it. Then update the subscription. Make sure you enter the node link and subscription URL in the correct places.
- Select the node you want to use and set it as the active server from the right-click menu. Latency tests are only a guide; they don’t replace testing actual access.
- In the system proxy menu, select “Automatically configure system proxy” or a similar option. For your first setup, choose the built-in rule-based routing mode so common domestic websites connect directly.
- Open a website that requires a proxy in your browser, then check your exit IP using an IP lookup site. Whether the lookup site uses the proxy depends on your routing rules, so don’t rely on a single result.
Selecting a node doesn’t mean all your apps will use the proxy. The system proxy mainly affects apps that follow Windows proxy settings. You don’t need to enable TUN during initial setup. If you need to route apps that don’t follow the system proxy, enable it according to the official instructions. This can help prevent conflicts between proxy tools.
3. How IP, DNS, and browser settings affect your connection
Your exit IP is the address websites see for a connection, determined by the route that request takes. DNS resolves domain names to addresses. If your IP has changed but a website still won’t load, the cause could be DNS, your routing rules, the node, or a website restriction. This alone doesn’t prove there’s a DNS leak.
Secure DNS, proxy extensions, and separate proxy settings in your browser can all affect how traffic is routed. To troubleshoot, first pause other proxy extensions, use the browser’s default proxy settings, and note your original Secure DNS configuration. Changing your exit IP won’t automatically clear your cookies, sign-in state, or browser fingerprint, so it doesn’t guarantee that a website will identify you as a new user.
4. Troubleshoot connection failures in this order
- Nothing loads: First clear the system proxy and confirm your local network works. Then check the active node, system time, and client error logs.
- Subscription update fails: Check that the URL is complete and hasn’t expired. The route used to update a subscription may differ from the one used to connect through a node, so don’t keep importing it repeatedly.
- Only some domains fail: Check which routing rule is being applied and compare results with another node. If the logs show a DNS resolution error, check your DNS settings. If needed, run ipconfig /flushdns in Command Prompt to clear the cache.
- Works in the browser but not in other apps: Check whether those apps follow the system proxy. Don’t assume the node is the cause.
Change one setting at a time and test again to help pinpoint the cause. When you’re done, clear the system proxy before exiting the client to avoid leaving Windows pointed at a local proxy port that is no longer running.
