When choosing a Windows VPN, first check whether global proxy and split tunneling cover the apps you actually use. Then assess startup and reconnect reliability. If you use services in mainland China alongside international websites, start with rules-based split tunneling. Switch temporarily to global mode when troubleshooting to narrow down the cause.
This hands-on comparison provides checks you can repeat on your own computer; it does not offer unverified speed rankings. The table compares how each mode works and where it may fit. It does not mean any client has passed every test. Check the installed version and your own results for specific settings, protocol support, and recovery behavior.
Global Proxy and Split Tunneling: Understand What Gets Routed
“Global” can refer to two different things: which connections enter the client, and which route they take once there. A system proxy typically provides a proxy endpoint to apps that follow Windows proxy settings; it does not automatically take over every connection on the computer. A browser may reach international websites while a game or command-line tool still connects directly. There is no contradiction.
TUN mode uses a virtual network interface and routing configuration to handle traffic. Its coverage is often broader, but it still depends on exclusion rules, permissions, firewall settings, and the client’s implementation. TUN and global mode are not synonyms: TUN can work with rules-based split tunneling, while a system proxy can send received requests through a selected exit route.
| Setting | Role and limits | Suitable scenarios | What to check |
|---|---|---|---|
| System proxy | Primarily affects apps that follow the setting; it does not guarantee that every process is covered | Browsers and desktop apps that support proxies | Whether the target app uses the system proxy or its own proxy settings |
| TUN routing | Handles connections through a virtual interface and routes; may require extra permissions | Apps that ignore the system proxy, or scenarios requiring broader coverage | Route conflicts, DNS settings, and UDP support |
| Global policy | Sends all captured traffic not excluded by rules through the selected exit route | Temporary troubleshooting or accessing services in one region | Whether services in mainland China or company intranets are affected |
| Rules-based split tunneling | Uses rules such as domains and addresses to choose direct or proxied routes, usually in order | Using mainland China work services alongside international websites | Rule order, the final rule, and where DNS queries are resolved |
Bottom line: Start with split tunneling for everyday use. If an app does not work, first check whether its traffic enters the client, then review the routing rules. Do not treat “switch to global” as a permanent fix for every problem.
Choosing a Client: Subscription Compatibility Matters More Than the Name
When choosing a Windows client, first check its download source, subscription format, maintenance status, and log readability. VPNJo provides an entry point for its Windows client. Visit the download panel for currently available versions and instructions. Do not assume that software with the same name on another platform offers the same features on Windows.
A subscription link lets the client retrieve nodes and configuration; it is not a fixed address for a particular node. A successful import only means the client has read the content. Also check the node list, update time, and connection status. Before sharing a screenshot or submitting a support ticket, hide the full subscription link, which may contain access credentials. If you suspect it has been exposed, check whether the panel offers a reset option.
Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different proxy protocols or protocol designs; changing a name does not convert one into another. The client’s core must support the protocols and parameters in the subscription. A protocol alone is no guarantee of a faster route. These names are included to explain compatibility and do not mean that VPNJo offers every protocol listed.
- Get the client from the service’s provided entry point, then review its Windows installation and permission instructions.
- Copy the subscription address from the panel and use the client’s subscription import option. Do not paste it into a field for an individual node configuration.
- Run an update. Confirm that the list appears without format or protocol parsing errors, then select a route.
- First verify connectivity in a browser, then test the work, gaming, or development tools you actually need.
Games and Work Apps: Check Each Connection Path
The browser works, but a work app does not
A desktop app may use the system proxy or its own network library or settings. Its login window and main application may also use different routes. So a working website does not verify the desktop app. Test the actual tasks: complete a login, sync a document, and upload an attachment. Then check the client connection log for the relevant domain and matched rule.
Take extra care with company intranets, shared folders, and enterprise remote-access software. A personal proxy’s TUN routes may conflict with the corporate network. On company devices, follow your organization’s requirements and do not override corporate DNS or security policies. Keeping intranet traffic direct before testing external access usually makes problems easier to pinpoint than sending every connection through the same exit.
Signing in to a game does not mean gameplay traffic is routed
A launcher download, account sign-in, and in-game session may use different domains, processes, and transport methods. UDP traffic in particular depends on the client, selected protocol, and server configuration. Do not assume a game is compatible just because its login page opens, or assume a general-purpose proxy can replace dedicated game route optimization.
During testing, check updates, entering the lobby, and an actual match separately. If the game only works with TUN enabled, continue checking for effects on other apps. If you see an anti-cheat warning, follow the game’s rules and official support guidance; do not try to bypass restrictions.
Check command-line tools separately
Terminal tools do not necessarily read the Windows system proxy automatically. Some support HTTP_PROXY, HTTPS_PROXY, or their own proxy settings, but syntax and support vary. Follow the tool’s documentation and enter the local listening address shown by the client. Do not copy ports from unknown sources or use a subscription address as the proxy server address.
Startup and Reconnect: Test the Full Recovery Process
“Start at startup” often means launching the client after you sign in to Windows, not connecting as soon as the system starts. The window opening automatically, the background core running, proxy settings taking effect, the subscription loading, and the exit route becoming available are separate states. Check the full process when evaluating a client, not just whether a process appears in Task Manager.
Save a working configuration first, then test restarting the computer, waking from sleep, switching networks, and recovery after manually disconnecting the network. Save your work before testing. Change one condition at a time; updating a subscription, switching regions, and changing split-tunneling rules together makes it hard to identify the cause.
- ✅ After signing in to the desktop, does the client start as configured and load the expected settings and mode?
- ✅ After startup, do your browser and commonly used apps work, rather than merely showing “connected” in the status bar?
- ✅ After waking from sleep or restoring the network, can new requests complete? Do existing sessions need to be refreshed?
- ✅ After manually exiting the client, do system proxy settings revert, and can you still access websites in mainland China?
- ✅ If TUN is needed, are permission prompts expected, and are there conflicts with other virtual adapters or the corporate network?
- ❌ Do not count the startup screen appearing, one webpage opening, or an old connection still working as proof of successful automatic recovery.
Automatic reconnect is not the same as connection protection. During an outage, the client may reconnect or allow some connections to fall back to a direct route; the behavior depends on traffic handling and protection settings. If the client offers connection protection, read its instructions and test how it works. Do not infer that all traffic will be blocked from the button label alone.
Internet access stops after quitting: First check whether the Windows system proxy still points to a local client that has stopped, then check the virtual adapter and routes. Note the original settings before restoring them. Do not delete unfamiliar adapters or disable system security protections as a first step.
Exit Routes and DNS Checks: Look Beyond the Connection Icon
When checking an exit route, distinguish between “a region is selected” and “the target request actually went through that route.” Use a trusted exit-check tool alongside the client logs. A browser’s result only confirms the route for that browser request; it says nothing about a game, terminal, or other app.
For DNS, check where domain lookups are sent. Some apps use their own encrypted DNS, while clients may use remote resolution, system resolution, or a mapping mechanism. Seeing a local resolver on a test page does not necessarily prove that all traffic bypasses the proxy, but it may indicate that DNS is not following the expected path. Check the configuration further.
Also consider IPv6. If the client only handles certain address types, an app may choose a different route. Do not disable features just to get an ideal result on a test page. First confirm that the client supports the relevant traffic handling, split-tunneling, and DNS policies, then adjust settings according to its official instructions.
When troubleshooting split-tunneling issues, you can switch temporarily to a global policy. If access is restored, rules, resolution, or the direct route merit closer inspection; it does not prove that the route itself is faulty. Switch back to split tunneling and use the logs to find the final matched rule. Fixing that rule is more practical than keeping global mode enabled, and makes it easier to keep services in mainland China accessible.
Routes and Pricing: Choose for Your Actual Needs
IEPL dedicated lines, transit, and direct connections describe different ways of organizing routes, not client protocol names. Generally, a direct connection reaches an exit from the local network, transit forwards traffic through an intermediate node, and IEPL uses dedicated Ethernet connectivity provided by a carrier. Labels alone cannot verify the route or experience; check the client and service documentation for the actual route type.
For extended work sessions on Windows, completing document syncs, downloads, and video calls reliably is usually more useful than a one-off speed test. Keep the task, traffic-handling mode, and local network conditions consistent when testing, and note where a failure occurs. Do not compare only region names or treat one result as a long-term performance guarantee.

Data resets monthly on the activation date; mid-cycle upgrades are prorated based on the remaining days. For ongoing downloads and video use, choose based on the panel’s data records rather than estimating usage from the number of desktop devices.
For occasional use, you can also compare data packages: ¥158 / 300GB, ¥358 / 1000GB, and ¥658 / 3000GB. They remain valid until used and never expire. See the plans page for full pricing. VPNJo requires no email address; you can create an account with a username and password, and a 14-day no-questions-asked refund is available. These facts do not replace compatibility testing on your own computer.
Final recommendation: For browsers and everyday work, start by testing the system proxy with rules-based split tunneling. If a target app does not use the proxy, then evaluate TUN. After choosing a client, test startup, reconnecting, DNS, and recovery after quitting with real tasks, then choose a plan based on actual data use.
