When choosing a Windows VPN, first check whether it routes the apps you need, then consider routes and pricing. A browser loading a webpage doesn't mean games and work apps use the same connection path. This guide explains how to compare global proxy modes, split tunneling, and app compatibility with repeatable tests—without presenting unverified performance claims as facts.
For everyday browsing and work, start with rule-based routing. To troubleshoot a connection to an international site, try global mode temporarily. For apps that ignore the system proxy, consider the client's virtual network adapter mode. This guide compares traffic-routing methods; it isn't an unverified brand speed ranking, and it doesn't assume that the WeiVPN client offers every option discussed below.
Understand system proxy, global mode, and virtual network adapters
Windows system proxy settings provide a proxy endpoint for apps that follow them. Browsers and some desktop apps do, but others may use their own network stack, separate proxy settings, or direct connections. Enabling “system proxy” does not mean that all traffic from your PC is routed through the proxy.
In a client, “global” usually refers to routing: connections that have already reached the proxy core are sent through the selected node. “Rules” route or block traffic based on domains, destination addresses, or other conditions. Neither setting determines which apps reach the core in the first place; assess that separately from traffic-capture methods such as the system proxy or a virtual network adapter.
Virtual network adapter mode, often called TUN mode, uses system routes to capture traffic from more apps and generally requires the appropriate permissions and driver support. Exclusions, network interfaces, and client implementation also affect what it captures, so turning it on doesn't guarantee that every connection is covered.
| Setting | What it does | Best for | Common misconception |
|---|---|---|---|
| System proxy | Provides a proxy endpoint to apps that follow the setting | Browsers and proxy-aware apps | Other apps may still connect directly |
| Global mode | Routes captured connections through the proxy | Isolating rule-matching issues | Doesn't capture traffic from every app |
| Rule-based routing | Chooses a connection route based on conditions | Using local services and international sites side by side | Outdated or misordered rules can match the wrong traffic |
| Virtual network adapter mode | Captures traffic from more apps through system routes | Apps that ignore the system proxy | May conflict with corporate networks or other tunnels |
How to Test a Windows VPN: Change One Variable at a Time
Before comparing results, note the client version, current network, selected node, traffic-capture method, and routing mode. Keep the network and target app the same. Don't switch nodes and update rules at the same time, or you won't know which change made a difference. Record outcomes such as “worked,” “failed,” error messages, and matched rules in a local note. There's no need to chase precise-looking speed test numbers you can't reproduce.
- Establish a direct-connection baseline. Disconnect the proxy and check the normal status of websites, local network devices, and work services. If something already fails without the proxy, you can't automatically attribute the problem to the VPN.
- Test system proxy with rule-based routing. Connect to a fixed node, reopen the target app, and check web access, account sign-in, and the actual task you need to complete. Don't rely on the client's connection icon alone.
- Switch to global mode temporarily. Keep the node unchanged. If the problem goes away, check whether the original rule sent the target domain down the wrong route. If it persists, check whether the app's traffic is reaching the proxy at all.
- Test virtual network adapter mode if needed. Enable it only if the client supports it and your network administrator allows it. Repeat the same task and check whether local network or corporate connections are affected.
- Restore your everyday settings and retest. Save any routing rules that worked, then restart the app to confirm them. After quitting the client, check that your regular network works again and that no inactive system proxy setting was left behind.
Separate observations from assumptions. A changed browser exit address only shows that the browser request used that route. To assess a game's or work app's route, check the client's connection log, matched rules, and the app's behavior. Before sharing logs, hide account details, internal network addresses, and subscription credentials.
How browsers, games, and work apps differ
Browsers: a page loading doesn't mean the whole service works
A browser may have its own proxy extension or secure DNS enabled. First check whether the extension overrides system settings, then test the page content, sign-in redirects, images, and downloads. A service often uses multiple domains, so fixing the main site rule may still leave login or resource-loading problems.
To check your exit address, start with the IP check on this site, but don't treat one result as proof for every app. Existing browser connections may continue using their previous route for a while. After changing modes, start a fresh connection before checking again.
Games: check connection type and actual gameplay
A game's launcher, updater, and gameplay process may use different connection methods. Signing in doesn't prove that gameplay traffic is routed through the VPN, and a successful download doesn't prove that real-time connections are stable. Some games use UDP, which requires support from the client, node, and relevant configuration. A protocol name alone doesn't guarantee compatibility.
During testing, record how sign-in, updates, matchmaking, and actual gameplay perform separately. Don't disable security software or modify anti-cheat components just to make a game recognize the network. Follow the game's regional and account rules, too; changing your exit region may trigger additional checks.
Work apps: preserve corporate network and local access
Corporate tunnels, virtual network adapters, and proxy clients may all change routes or DNS settings. If shared drives, intranet portals, or printers stop working, first pause any newly enabled traffic-capture method, then check internal network ranges and corporate domain routes. Don't use global proxy as the default fix for corporate network issues.
Have an administrator approve settings on managed devices. If a work app has its own proxy option, check whether it inherits system settings first. Avoid stacking settings in the app, system, and client: if authentication fails, it becomes much harder to pinpoint the cause.
How to Check Routing Rules and DNS Leaks
Rules are usually checked in order. A broad rule placed too early can override a more specific rule below it. If a service stops working, first check which rule actually matched, then decide whether to change a domain rule, destination range, or app rule. Process-based rules depend on whether the client can identify processes; don't copy settings from another platform without checking.
A DNS leak check asks whether DNS queries follow the intended route. If proxy traffic uses a different exit but DNS still goes through the local network, that may not meet your privacy expectations. Conversely, a test page showing resolvers in another region doesn't by itself prove a leak. Public DNS routing, caching, and browser secure DNS can all affect the results.
Start by defining what you expect: which domains should use proxy DNS, and which corporate or local domains must keep their existing resolution path. Then compare the client DNS settings, browser settings, and test results. If you use a mapping method such as fake-IP, check the client documentation for how to configure exceptions for local network services.
- ✅ Check the rule matched by the target connection and its final route—not just the mode name.
- ✅ Check browser secure DNS, client DNS, and corporate network requirements separately.
- ✅ Add precise exceptions for local services only when needed, then verify the change.
- ❌ Don't treat disabling the system firewall as a routine troubleshooting step, or import a full ruleset from an unfamiliar source.
Importing subscriptions, launching at startup, and running in the system tray
A subscription link is a credential used to retrieve nodes or configuration, not a public URL. Copy it from the service dashboard and confirm that your client supports its format. Support for Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC depends on the client and core version. Being able to import a link doesn't mean every protocol and configuration field is supported.
With WeiVPN, visit the dashboard download page for the Windows client and instructions. After importing, update the subscription and check the node list and any error messages. Never paste a full subscription URL into an unfamiliar online conversion site just to make it work. If you need help, describe the error through the support page, and hide the link and account details in screenshots.
Launch at startup, connect automatically, and minimize to the system tray are separate options. First verify a manual connection, then enable startup options that the client actually offers and check their status under Windows Startup apps. Closing the window may only minimize the client to the tray; you may need to quit from the tray menu. The exact behavior depends on the client.
After restarting, check that the client launched, the subscription is available, the proxy is working, and the system proxy is restored after you quit. If the client relies on the system proxy, an unexpected exit may leave a setting that points to a stopped local service. Check Windows proxy settings rather than repeatedly reinstalling your browser.
Routes and plans: choose for your needs, not by the label
Direct, relayed, and IEPL dedicated routes describe different network paths or transport methods, not speed tiers. A relay typically forwards traffic from an entry point to an exit; IEPL refers to dedicated-line transport. Real-world performance also depends on the entry network, exit interconnection, congestion, and destination service. Without clear route details, don't assume a route is IEPL, and don't use the number of regions to predict gaming performance.
WeiVPN offers 100+ countries, 240+ routes, and unlimited devices, with support for Windows, macOS, iOS, Android, and Linux. See the route list, then test the apps you use with the steps above. Device limits and the performance of an individual connection are separate considerations.
Monthly plans are ¥9.9/month for 60GB, ¥18/month for 250GB, and ¥28/month for 500GB. Data resets monthly on the activation date; mid-cycle upgrades are prorated for the remaining days. Data packs cost ¥158/300GB, ¥358/1000GB, and ¥658/3000GB; they expire only when used up and never otherwise expire. For regular use, compare the monthly plans; for occasional use, consider a data pack based on your actual usage. Neither option is automatically better for everyone.
WeiVPN requires no email address; you can register with a username and password. Payment options include Alipay, WeChat Pay, and USDT, and the service offers a 14-day no-questions-asked refund. The “anonymous, no-logs” statement describes the privacy policy; it doesn't mean that account apps, payment services, or destination websites keep no records of their own.
