Common VPN Questions for Beginners: 10 Frequently Asked Questions Answered

Common VPN questions for beginners are usually not about the “Connect” button itself, but what happens after connecting: whether traffic is counted twice, why speeds change between routes, which client should receive a subscription link, and which sites should use the proxy. The answers below follow the order of real-world use and include checks you can perform yourself.

The basics of devices, data, and speed

Question 1: Can I use the VPN on multiple devices at the same time?

This depends on the service terms, not on VPN technology itself. Some services license individual devices, some limit simultaneous connections, and others allow unlimited devices. VPNHe allows unlimited devices, so you can import the subscription linked to the same account on a computer, tablet, and other supported platforms.

Unlimited devices does not mean every device must use exactly the same settings. A computer may benefit from per-app split tunneling, while a tablet may work better with domain- or rule-set-based routing. Keeping separate configurations for each platform reduces the chance that a rule change on one device affects the others.

If performance drops after several devices connect at once, check whether any device is syncing files, downloading updates, or playing high-bitrate video. Route bandwidth is shared by concurrent tasks, and a single background process can make other devices seem slower than the route actually is.

Question 2: How is VPN data usage calculated?

Common plans count uploads and downloads that pass through the proxy tunnel. Web browsing, video streaming, cloud-drive syncing, software updates, and video calls all use data; if traffic passes through the selected node, it may count toward plan usage. Whether usage is measured in one direction or both should be confirmed in the user panel and plan rules.

The routing mode directly affects usage. When rules send local sites directly, that traffic typically does not pass through a remote node; in global mode, more application traffic enters the tunnel. System backups, photo syncing, and game-platform updates often run in the background. If usage rises faster than expected, beginners should check these tasks first.

• ✅ Check the plan’s remaining data and reset rules in the user panel.
• ✅ See whether the client is using global mode or rule-based split tunneling.
• ✅ Pause cloud drives, system updates, and large file syncs, then monitor usage again.
• ✅ Compare the client’s traffic records with the operating system’s per-app data statistics.
• ❌ Do not judge usage by the number of web pages visited alone; media and background tasks can differ dramatically.

Question 3: If the connection is slower, does that mean it is being throttled?

A single speed test cannot prove throttling. Once data travels through a remote exit, the path is longer and performance is also affected by the local network, congestion at international gateways, node load, protocol handshakes, the destination server, and wireless signal quality. Slower speeds in the evening, one slow website, and consistently slow performance across all apps do not point to the same cause.

When troubleshooting, first disconnect and confirm that the local network works normally. Then connect to a geographically closer node and try another route in the same region. If only one app is affected, check split tunneling and DNS; if every app is slow, investigate the route, protocol, and local network quality.

When to connect, change devices, and migrate settings

Question 4: Should the VPN stay on all the time?

There is no single answer for every situation. Keep it connected when using public networks, accessing services that require an exit location in a specific region, or keeping a particular app inside an encrypted tunnel. Disconnect or use split tunneling when accessing only local services, working with latency-sensitive devices on a local network, or troubleshooting network issues.

For long-running connections, consider enabling the client’s automatic reconnect and network-change protection, but do not treat “connected” as a permanent state that never needs checking. After a computer wakes from sleep, switches between wired and wireless networks, or a router reconnects, the tunnel may need to be established again. Checking the client status and exit address is more reliable than looking only at the system network icon.

Always-on use is best suited to people who understand which traffic should enter the tunnel. If you are new to VPNs and do not yet understand split-tunneling rules, connect as needed first, confirm how your apps behave, and then enable automatic connections gradually.

Question 5: What should I do after changing computers or reinstalling the operating system?

You usually do not need to migrate the old client’s cache files. A safer approach is to install a supported client on the new device, retrieve the subscription link again from the user panel, and import it according to the platform’s requirements. This brings in currently valid nodes without carrying over outdated rules, expired certificates, or old local paths.

Before migrating, note any split-tunneling rules, DNS options, and automatic-connection preferences you changed. A subscription provides server-side configuration; user-created local rules may not sync with it. If the old device is no longer in use, remove its configuration from the system and securely handle any text files or screenshots that contain the subscription link.

1. Install a client that matches the new device’s system architecture.
2. Copy the current subscription link again from the user panel.
3. In the client, choose “Import via URL” or “Add remote subscription.”
4. Update the subscription and choose a node in a suitable geographic location.
5. Test websites and DNS first, then restore your custom split-tunneling rules.
6. After confirming that the new device is stable, remove sensitive configuration saved on the old device.

Understanding protocol and route names

Question 6: How should I choose between Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC?

These names generally refer to proxy protocols or transport schemes, and not all of them are traditional system-level VPN protocols. The client takes over traffic through a system proxy or virtual network interface, then sends data to nodes according to the rules. Choose based on the configurations actually offered by the server, client compatibility, and the current network environment—not on the protocol name alone.

Shadowsocks has a relatively simple structure and broad client support. VMess and VLESS are common in clients that support multiple transport methods; VLESS relies more heavily on its outer transport and security settings. Trojan traffic is typically built on TLS. Hysteria2 and TUIC follow QUIC-based approaches and focus more on transport performance in lossy networks, but may be affected by networks that restrict UDP.

No protocol has a fixed ranking that applies to every network. The same protocol can perform differently depending on the carrier, routing, device performance, and client implementation. If the subscription already provides usable nodes, beginners should start with the client’s recommended settings. Change protocols only when stability or compatibility issues arise, and compare them under similar route conditions in the same region.

Question 7: What is the difference between direct routes, relay routes, and IEPL?

A direct route sends the device straight to a remote node. The path is simple, but performance depends heavily on the public route from the local carrier to the node’s location. A relay route first sends traffic to a nearby entry point, then forwards it to the exit through an optimized path, reducing the impact of unstable public-network segments. IEPL usually refers to an international Ethernet private-line connection, emphasizing dedicated transport across the international segment, although the actual product may still include entry, exit, and public-network access components.

A route name describes its design, not its real-world performance. A private line does not guarantee that the local wireless network, entry access, or destination site will never be congested; a direct route is not necessarily slower and may be more direct when routing is good and the distance is suitable. Choose nodes based on the target region, current network, and content you are accessing—not simply the route name that sounds more advanced.

Subscription imports and differences between platform clients

Question 8: Why are there no nodes after importing a subscription link?

Common causes include an incomplete copy of the link, a client that does not support a protocol included in the subscription, an outdated subscription, an incorrect system clock, or a network that cannot reach the subscription address. A subscription link is not an ordinary web address. Seeing encoded text or downloaded content after pasting it into a browser does not mean the link is broken.

Different clients may label the entry as “Remote configuration,” “Import from URL,” “Add subscription,” or something similar. After importing, you usually also need to run an update before choosing a route from the generated node list. Adding the link without updating is the first thing to check when the list appears empty.

Troubleshooting order
Confirm that there are no spaces or line breaks at either end of the link
Confirm that the client supports the protocols included in the subscription
Run a remote subscription update
Check that the system date and time are correct
Switch networks and retrieve the subscription again
If there is still no result, submit a ticket with the error details

Windows and macOS clients can usually use system-proxy or virtual-network-interface modes, and desktop systems make connection logs easier to inspect. Mobile platforms are more affected by background restrictions; switching networks or entering power-saving mode may require the connection to be established again. Clients also differ in how they name rule formats, DNS modes, and virtual-interface permissions, so do not copy every toggle from another platform without checking it.

If a client asks to install a virtual network interface or add a system network configuration, first verify the software source and review the system permission prompt. A system proxy mainly affects apps that follow proxy settings; virtual-interface mode can take over more traffic, but is also more likely to conflict with other network tools, enterprise security software, or local virtualized networks.

• ✅ Get the latest subscription from the user panel instead of using shared configurations from unknown sources.
• ✅ Update the subscription after importing it, then choose a node to connect.
• ✅ Keep the client’s error logs so you can distinguish resolution failures, handshake failures, and timeouts.
• ✅ Before changing clients, confirm protocol compatibility and configuration format.
• ❌ Do not run multiple clients that take over the system proxy or virtual network interface at the same time.

DNS, split tunneling, and everyday troubleshooting

Question 9: What is a DNS leak, and how should I check for one?

DNS resolves domain names into network addresses. After connecting to a proxy, a DNS leak can occur when domain lookups are still handled directly by the local network’s default DNS while web traffic uses a remote exit. This creates a mismatch between the DNS path and the exit path. It may reveal the range of domains being queried, cause conflicting region detection, or resolve to an address unsuitable for the current exit.

When checking, do not look only at the exit IP; also find out which resolver handles DNS requests. If the client offers settings such as “Remote DNS,” “Proxy DNS,” or “Prevent DNS leaks,” enable them in line with the current operating mode. With a system proxy, some apps may initiate encrypted DNS requests themselves; with a virtual network interface, the client can usually take over more queries, but the rules still need to be configured correctly.

If a site opens its homepage but cannot load resources, the same domain behaves differently in different apps, or the original region is still detected after changing the exit, clear the system DNS cache, restart the browser, check secure DNS settings, and reconnect to the route in that order. Do not change every DNS option in the system, browser, and client at once, or it will be difficult to identify which setting helped.

Question 10: How should I configure split tunneling, and what should I check first when a connection fails?

Split tunneling sends traffic that needs a remote exit into the tunnel while keeping local services, local-network devices, and apps that do not need a proxy on a direct connection. Common rules match domains, IPs, applications, or rule sets. Rules are generally processed in order, so specific exceptions should come before general rules; the default rule then determines where unmatched traffic goes.

Beginners do not need to maintain a huge custom list from day one. Start with the basic rules supplied by the client or subscription, confirm that common sites and apps work, and then add rules for clear exceptions. If a local site takes an unnecessarily distant route, a printer becomes unreachable, or an app refuses to connect, check whether it was incorrectly sent through the proxy.

When a connection fails, the error message is more useful than “it won’t connect.” A timeout usually points to a problem with the path, port, or network environment; an authentication failure may indicate an invalid configuration; certificate or TLS errors require checking the system time, domain, and configuration; if the client connects but there is no internet access, check DNS, routing, the system proxy, and virtual-interface conflicts.

1. Disconnect the current connection and confirm that the local network itself can access the internet normally.
2. Update the remote subscription so you are not using node parameters that have changed.
3. Choose another node in the same region to determine whether the issue affects one node or the service more broadly.
4. Close other proxy, acceleration, or virtual-interface tools to rule out takeover conflicts.
5. Check the system date, DNS settings, and the client’s operating permissions.
6. Keep the error log, node name, system platform, and reproduction steps, then submit a ticket.

Habits worth keeping as a beginner

Stable use does not depend on constantly changing parameters. It depends on a clear baseline: knowing the state of the local network before connecting, knowing where the current node and protocol came from, knowing which apps should use the proxy, and knowing how to restore default settings when something fails. Change one variable at a time to avoid mixing route, client, and system-setting problems together.

Subscription links, client logs, and account credentials serve different purposes. Keep the subscription link secure; logs are useful for troubleshooting, but check them for connection addresses or local paths before sharing; use a unique password combination for the account. VPNHe does not require an email address for registration, so save the username and password securely to avoid losing access to your account details when changing devices.

When choosing a service, also consider whether its rules are clear, its route information is understandable, and its client download path is easy to find. VPNHe covers 120+ countries and 180+ routes, with unlimited devices. When there are many routes, you do not need to test every one: filter by the target region first, then keep the options that remain stable on your actual network.

• ✅ Keep a default configuration that connects successfully as a troubleshooting baseline.
• ✅ Record the original settings before changing DNS, protocols, or split tunneling.
• ✅ Update the subscription regularly from the user panel instead of rewriting node parameters manually.
• ✅ When submitting a problem, include the platform, client, error message, and reproduction steps.
• ❌ Do not publish subscription links, account credentials, or complete configurations on public pages.
