Start with Windows VPN Options and Traffic Coverage
Choosing a Windows VPN is about more than node names. A browser opening a webpage does not mean games, meetings, or corporate intranet apps will work too. First identify which programs need a proxy, then check whether the client can handle their traffic and restore the original network when disconnected.
This hands-on comparison uses repeatable checks on your own device. It does not provide unmeasured speed rankings or claim that any client has been tested with every game and work app. The table compares how each method works; verify compatibility with your own computer, network, and target apps.
First, distinguish the service from the client. A subscription service provides routes, access credentials, and data allowances; the client imports configurations, selects an exit, and applies rules. The same subscription may behave differently across clients because proxy cores, virtual adapters, DNS handling, and rule implementations vary.
How to choose: If you mainly use a browser, start with the system proxy and rule-based routing. If an app ignores the system proxy, consider a virtual network adapter. For games and corporate work, check protocol, routing, and permission requirements first; “global” mode does not guarantee compatibility.
Global Proxy, Rule-Based Routing, and TUN Compared
Clients often put options from different layers in the same interface. “Global” and “rules” usually determine which exit traffic uses; “system proxy” and “TUN” determine how traffic reaches the client. The former are routing policies, while the latter are traffic-capture methods—they are not interchangeable.
| Option | What it does | Suitable for | What to check |
|---|---|---|---|
| System proxy | Directs apps that follow system settings to use a local proxy | Browsers and some desktop apps | Whether the target app reads the system proxy |
| Global policy | Sends traffic that has reached the proxy core through the selected exit | Temporarily checking whether rules are misrouting traffic | Does not capture every program |
| Rule-based routing | Selects an exit by domain, address, or supported process rules | Using international websites alongside local services | Rule order, resolution results, and fallback policy |
| TUN virtual adapter | Captures traffic matching routes through a virtual network interface | Apps that ignore the system proxy | Permissions, routes, DNS, and conflicts with other tunnels |
For example, the system proxy may be enabled while a game uses its own network interface. Switching to a global policy may not help: the game’s traffic has not entered the proxy core. Conversely, TUN can be used with rule-based routing so local services connect directly instead of sending all traffic to a remote exit.
Some command-line tools and background services use their own proxy settings and may not follow Windows settings. When testing download tools, software updates, or development environments, check each program’s documentation and the client’s connection logs instead of looking only at the browser’s exit.
Check the Client, Protocol, and Subscription Import
Windows clients mainly differ in supported proxy cores, rule editing, TUN implementation, and service modes. A lightweight interface suits everyday switching; a client with stronger rule support may suit complex work networks, but also requires configuration maintenance. Screenshots alone are not a reliable way to judge capabilities.
Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different protocol options, not node labels that can be freely swapped. Hysteria2 and TUIC are based on QUIC and rely on UDP connectivity; UDP forwarding for other protocols also depends on the client, server, and configuration. A protocol name alone does not prove that gaming will be faster.
VLESS does not provide encryption by itself, so assess the secure transport mechanism in the actual configuration. Trojan typically uses TLS. Check the complete configuration supplied by the service and the client’s supported features. Do not disable certificate verification just to make an import work, and do not add parameters whose purpose is unclear.
- Check supported formats first. Confirm the client instructions, subscription format, and protocols in the service panel, then get the client from a trusted source. Different configuration formats cannot be converted just by changing a file extension.
- Review the import result. Check that the node list and policy groups have been created and that subscription updates completed without errors. Seeing a configuration name does not mean its node contents have loaded.
- Verify a basic connection. Select an exit, enable the capture method suitable for the task, open the target website, then check the client logs for the matched rule and exit.
- Add advanced features last. Once the basic connection works, test TUN, custom rules, and startup behavior. Change one setting at a time to make problems easier to trace.

How to Test Games, Meetings, and Corporate Intranet Apps
Browsers and everyday browsing
First record whether the target webpage opens with the proxy off, then retest with the system proxy and rule mode enabled. Use My IP to check the browser’s current exit, and review the connection logs. A changed exit only describes the route for that webpage request; it does not prove that other programs are captured too.
Game sign-in and matches
A game launcher’s downloads, account sign-in, and match connections may use different domains and protocols. After signing in, also test matchmaking, voice chat, and an actual match. Opening the store page is not enough to confirm compatibility. If the game uses UDP, check that the entire route supports the required forwarding.
Do not run multiple game accelerators and network tunnels at the same time during testing, or it will be difficult to determine which route is in use. Follow game requirements if anti-cheat or security policies restrict network tools; do not try to evade them. An exit in another region may also affect server selection and account risk controls, so avoid switching regions repeatedly during sign-in.
Meetings and remote work
Meeting apps may handle sign-in, media, and screen sharing separately. Test joining, listening, speaking, and sharing rather than checking only the sign-in screen. If rule mode works but global mode does not, first check whether media traffic that could connect directly is being routed remotely.
Corporate VPNs, intranet DNS, and private proxies may compete for the default route or DNS resolution when running together. Even if a company domain connects directly, it may still require corporate DNS to resolve. Do not change policies on a managed device without authorization. Confirm permitted co-existence options with an administrator; if needed, disconnect the private proxy before connecting to the work network.
- ✅ Record the capture method, policy, exit region, and target app instead of noting only “works” or “doesn’t work.”
- ✅ Test sign-in, core tasks, and sustained connections separately, then check again after waking the computer from sleep.
- ✅ Disconnect the proxy and retest local websites, printers, and corporate resources to confirm the network recovers.
- ❌ Do not use a webpage speed test as a substitute for checking game packet loss, meeting audio, or corporate intranet access.
Troubleshooting Split-Tunnel Rules and DNS Leaks
Rule-based routing commonly fails because of incorrect rule order, missing domains, or a request reaching the core with only its destination IP remaining. A typical approach is to handle clearly identified local and corporate resources first, then specified services, and set a fallback policy last. Check the documentation for the core in use to confirm its matching order.
DNS resolution determines how the client gets a destination address. If a query that should be handled through the tunnel is unexpectedly sent to a resolver on the local network, the domain being accessed may be exposed. DNS leaks and whether traffic is encrypted are separate issues; a resolver’s displayed country alone cannot confirm a leak.
Encrypted DNS in the browser, Windows resolution settings, and the client’s DNS feature may all run at once. When troubleshooting, first decide which domains should be resolved on the proxy side and which corporate domains should use an internal resolver. Then compare connection logs, DNS test results, and app behavior instead of applying an unfamiliar configuration.
Some clients use Fake-IP, mapping domains to internal addresses to help with routing. This can affect software that relies on real addresses or a special resolution process; decide whether to exclude a domain based on reproducible results. If the network supports IPv6, check its traffic and DNS paths too rather than inspecting only the IPv4 exit.
Startup, Routes, and Choosing a Plan
Starting at boot does not mean the proxy is ready as soon as the computer starts. A user-session app, a background service, and TUN features that require elevated permissions may be in different states. First confirm that a manual connection is stable, then enable startup as described by the client. After restarting, check subscription loading, exit selection, proxy settings, and target apps—not just the system tray icon.
If the browser cannot connect after an unexpected exit, first check whether Windows proxy settings still point to a local listening address that has stopped, then check whether the virtual adapter and routes were restored. To return to a direct connection, turn off the relevant proxy setting or use the client’s recovery feature. Do not delete unfamiliar network components.
For routes, direct connection usually means a device connects to the remote entry directly; a relay forwards traffic through an intermediate entry. IEPL typically refers to international Ethernet private line transport. A private line describes part of the transmission path; it does not mean every app uses a dedicated end-to-end network or guarantee low latency. Home internet, entry location, congestion at the exit, and the destination server still affect performance.
When viewing the route list, consider coverage alongside your actual destinations. R9VPN covers 100+ countries and 210+ routes, with no device limit. These describe the service’s coverage and should not be taken to mean that every region, game, or work app will perform the same way.
For billing, monthly subscriptions are ¥9.9 / 60GB, ¥18 / 250GB, and ¥28 / 500GB, with data resetting monthly on the activation date; data packages never expire. Fixed work use and occasional browsing have different usage patterns, so check your actual data use before comparing options on the plans page. R9VPN offers a 30-day no-questions-asked refund; see the site’s instructions for how to request one.
In short: First confirm the target app is captured correctly, then verify routing rules, DNS, and recovery after disconnecting. Enable startup last. Browser users do not need to turn on TUN just to get “more features”; users working with games or corporate apps should not switch directly to a global policy without checking compatibility.
