Confirm It’s Working: Connection vs. Traffic
How can you tell if your VPN is working? Don’t rely on the client’s “Connected” status alone. Compare your exit IP before and after connecting, check how DNS queries are routed, and test both your browser and the apps you use. The goal is to verify specific requests—not just a status light.
“Connected” usually means a tunnel has been established or a local proxy service has started, depending on the client. It doesn’t necessarily mean system routing, browser proxy settings, or per-app routing are configured correctly. A successful latency test only shows that the test request received a response; it doesn’t prove that a website’s pages, sign-in, and downloads all use the same exit route.
First, be clear about what you expect. Rule-based mode typically sends some requests directly and routes others through the proxy. If a test site matches a direct-connection rule, seeing your regular exit IP may be expected. Conversely, a foreign IP on one test page doesn’t prove that other apps or protocols are covered.
Exit IP: Set a Baseline, Then Compare
Open our network check page and note the public IP, network provider, and location it shows. To establish a baseline, disconnect the proxy and close any work pages you want to protect; run only the checks you need. If testing without the proxy isn’t suitable for your network, skip the baseline and account for the uncertainty.
- Check the selected node and operating mode in your client, and confirm that system proxy or virtual adapter mode is enabled. Selecting a node alone may not route your traffic through it.
- Reconnect and open the check page again. If needed, close the old tab first so you don’t mistake cached results for new ones.
- Compare the full IP address, then check the network provider and location. Location databases can be inaccurate, so don’t rely on the city name alone.
- Look for the test site in your client’s connection list or rule-match log to see whether it was routed through the proxy or connected directly.
- Open the target service using the same mode and check its pages and key features—not just the test site.
If the exit IP changes and the request matches the expected node, you can confirm that this test request used the corresponding proxy route. However, the same node name doesn’t guarantee a fixed exit IP: the service may use different exits, and its location label may not exactly match the database. If the result is unclear, note the time, node name, and result, then ask the service’s support team to verify.
| Observed result | What it tells you so far | What to check next |
|---|---|---|
| Client shows “Connected” | The client reports an active connection | Check traffic routing and rule matches |
| Test page shows a different exit IP | The request from that page used a different exit | Check whether the target app uses the same route |
| IP unchanged in rule-based mode | The request may be direct, or traffic may not be captured | Check which rule matched the test domain |
| IP changed, but the website denies access | The proxy route may be working; the service may have other restrictions | Check regional policies, account status, and the error message |
| Browser works, app doesn’t | Different apps may use different network routes | Check app proxy settings, per-app rules, and tunnel coverage |
DNS: Check the Resolution Route, Not Just the Location
DNS translates domain names into IP addresses. Routing a web connection through a proxy doesn’t automatically route its DNS queries through the proxy too. A traditional system proxy may only cover connections from apps configured to use it. Whether a domain is resolved locally or by the proxy also depends on the app, proxy type, and client settings.
A DNS leak generally means that DNS queries you expected to travel through the tunnel were instead sent to a resolver outside it. You can’t determine this just because the DNS server and proxy node appear to be in different countries. Public DNS services may use distributed servers, and the resolver location reported by a test tool may not be the server your device contacted directly.
Start by checking your client’s DNS settings: does it handle system DNS, apply different rules to direct and proxied domains, or use its recommended configuration? Then check your browser’s Secure DNS settings. A browser may resolve domains separately over encrypted DNS. That traffic might use the proxy or take another route, so check the connection logs to find out.
- ✅ Check your client’s documentation to see how DNS is handled in the current mode; don’t replace it with a public resolver at random.
- ✅ Check for conflicting or overriding settings across browser Secure DNS, system DNS, and client DNS.
- ✅ After changing settings, close the affected apps before testing again to avoid interference from cached results and existing connections.
- ❌ Don’t assume that a resolver in a different location means your actual network address has been exposed.
- ❌ Encrypted DNS isn’t a substitute for a proxy: it protects DNS traffic but doesn’t automatically change the route used to access websites.
DNS test pages usually ask your browser to look up specific domains, then check where those lookups came from. The results mainly cover DNS requests made by that browser, not every app on your device. If your client uses virtual DNS mapping, an app may see an internal mapped address, which shouldn’t be mistaken for an ordinary public IP address.
Per-App Checks: Browser Access Isn’t Enough
Apps on Windows, macOS, and Linux vary in how they handle system proxy settings. A browser may follow the system configuration, while command-line tools, games, or desktop apps may need separate setup. Browser extensions usually affect only that browser, so they don’t show whether other apps are routed through the proxy.
On iOS and Android, tunnel clients often use system networking interfaces to route traffic, but per-app policies, exclusions, and other network settings can still affect what’s covered. App selection on Android and split-tunneling options on iOS depend on the client and system configuration. Don’t assume instructions for one platform apply to another.
Use the target app to do something real—load a workspace, open a document, or start a call—and watch the client’s connection list. A webpage loading successfully doesn’t mean voice or video traffic will work: some real-time communications use UDP, which the current proxy route may not handle correctly. Test the features you actually need; there’s no need to route every unrelated app.
Rule-Based Mode, Global Mode, and Virtual Adapters
Rule-based mode chooses an exit according to conditions such as domain, address, or process. Global mode usually applies one policy to traffic that has already reached the proxy core. It may not capture apps that bypass the system proxy, so “global” doesn’t guarantee that all traffic from the device goes through the tunnel.
Virtual adapter mode can generally capture more traffic at the network layer, but it still depends on routing, permissions, DNS settings, and exclusion rules. Read the client’s documentation before enabling it, and avoid conflicts with access software required by your organization. When testing is done, switch back to a mode that suits everyday use while preserving access to local networks as needed.
Common Reasons a VPN Shows Connected but Isn’t Working
Local proxy started, but system traffic isn’t routed through it
Some clients separate “Start proxy core” from “Set system proxy.” First, check that traffic routing is enabled, then see whether your browser has a separate manual proxy setting. If several proxy tools are running at once, they may override each other’s system settings. Stop any tools you don’t need and test again; running them together isn’t a reliable setup.
Subscription imported, but the configuration is outdated or rules don’t fit
A subscription link retrieves client configuration. Importing it successfully only confirms that the link or configuration could be read. Nodes may need updating, and the target domain may match an unsuitable rule. Use the client’s update feature and confirm that the selected configuration is active. Don’t share a full subscription link in a public screenshot; it may contain access credentials.
IPv6 or another request path isn’t being routed as expected
If your device has both IPv4 and IPv6 connectivity, check the results for each separately. Routing one address family through the proxy doesn’t mean the other follows the same path. First check whether the client supports and captures that traffic. Disabling a system networking feature isn’t a general-purpose fix.
WebRTC checks in browsers also require distinguishing between address types. A local network address or privacy-masked localhost identifier doesn’t mean your public exit IP has been exposed. If an unexpected routable public IP appears, check your browser policies, UDP route, and tunnel coverage.
Network changed, but the old session didn’t recover
After switching from hotel Wi-Fi to a mobile network, or waking a device from sleep, the client may still show connected even though the old connection no longer works. First, confirm that the current network is available and check whether the guest network requires web-based sign-in. Then reconnect to the node and reopen the target app. Don’t enter subscription credentials on an unfamiliar sign-in page.
Service restrictions mistaken for a failed VPN connection
A service may restrict access based on IP reputation, account region, payment details, or its own policies. A changed exit IP followed by a regional restriction doesn’t necessarily mean the client has failed. Check the specific error and follow the service’s rules. Repeatedly switching locations may not help and could trigger additional account verification.
Narrow Down the Issue and Gather Support Details
Troubleshoot in this order: local network access → client traffic routing → test request exit → DNS → target app. The protocol used by a node or whether a route is labeled direct or relayed doesn’t replace these checks. Connection methods can affect routing and compatibility, but a label alone doesn’t prove that a request is taking effect.
If you contact support, include your operating system, client name, time of the issue, selected route, operating mode, and exact error. Note which apps work and which don’t. You can attach a screenshot of rule matches after removing sensitive details. Don’t share your password, full subscription URL, or unrelated account information; avoid publicly posting the public IP shown on a test page.
Bottom line: To confirm that your VPN is working for the scenario you need, match a specific request to its actual exit and expected routing rule. A changed exit IP is one piece of evidence; DNS and per-app checks help fill in the gaps. Passing a test doesn’t mean all traffic will always use the same route. Recheck after changing networks or settings.
For initial setup, follow the quick-start guide to check the import and connection steps. If you need support, send a request through the user panel. 4BVPN’s privacy policy states that it keeps no logs. That policy doesn’t replace checking traffic routing on your device, and it doesn’t prevent a website from recognizing an account you’ve signed into.
