10 Common VPN Questions, Answered in One Guide

The ten VPN questions beginners ask most often focus on accounts, data, speed, protocols, and connection checks. Installing the client is only the starting point. Whether a connection actually works depends on importing the subscription correctly, choosing a route that suits the current network, applying the expected split-tunneling rules, and verifying that both the exit IP and DNS follow the intended path.

This guide focuses on practical operation rather than product promotion. Start with the default settings, complete one connection and verification, then adjust the protocol, route, and split-tunneling rules for your use case. Changing one variable at a time makes problems easier to isolate than switching several options at once.

Question 1: What do I need to prepare before getting started?

You generally need to create an account, obtain a client, import a subscription, and choose a route. 74VPN does not require an email address for registration; a username and password are enough. Store the password separately and never reuse it on other sites. After installing the client, retrieve the subscription details from the user panel. Installing the app without importing a subscription will not automatically provide connectable nodes.

A subscription link is not an ordinary web address. It passes node names, server addresses, ports, protocol types, and authentication parameters to the client. Some clients fetch configurations from a link, while others also support pasting an individual node. For a first setup, import the full subscription so route changes can be synchronized by updating it instead of entering nodes one by one.

Question 2: Can one account be used on multiple devices?

Shared use depends on a service’s device policy, not on VPN technology itself. Some services count logged-in clients, some count simultaneous connections, and others limit the number of saved devices. 74VPN supports unlimited devices, so Windows, macOS, iOS, Android, and Linux devices can each import the subscription through their respective clients.

Unlimited devices does not mean every device must use the same route. A computer on a home network may benefit from a stability-focused route, while a mobile device may need a protocol better suited to changing networks. If several devices fail at the same time, test them separately first to determine whether the issue comes from the account, the local network, or a particular client configuration.

• ✅ Install the client that matches each device’s operating system.
• ✅ Import the subscription on trusted devices and update it regularly.
• ✅ Keep LAN rules enabled on devices that need access to local printers or network storage.
• ❌ Do not post the subscription link in group chats, public documents, or code repositories.
• ❌ Do not assume that every app uses the tunnel just because the client says “Connected.”

Question 3: How is VPN data usage measured?

Data usage usually means the upstream and downstream traffic relayed through the service’s servers. Browsing, downloading files, streaming video, syncing cloud storage, and system updates all consume data. The file size shown to users may not match the final total because transmission also includes handshakes, encryption overhead, retransmissions, and background app requests.

Split-tunneling mode directly affects what is counted. With a global proxy, most proxyable traffic enters the tunnel; with rule-based routing, only destinations matching proxy rules pass through the node. A browser extension affects only the browser, while a system proxy or virtual network interface may take over more apps. Before judging data usage, confirm which mode the client is running.

Video quality, autoplay, cloud-sync jobs, and large updates usually consume far more data than ordinary text browsing. To reduce usage, disable unnecessary background syncing first, then set local sites and LAN addresses to direct access. Do not repeatedly refresh the dashboard to estimate one app’s exact consumption. A more reliable approach is to combine the operating system’s per-app traffic statistics with observation of which programs keep transferring data.

Question 4: Is a slower connection after connecting caused by throttling?

A single drop in download speed is not enough to prove throttling. A VPN path adds client-side encryption, the access network, node forwarding, and the destination’s response time to the direct connection. Evening congestion, wireless interference, cross-region routing at the destination, or a protocol that does not suit the current network can all reduce speed.

Keep test conditions consistent while troubleshooting: use the same device, network, and destination, and change only one variable. First compare disconnected and connected states, then switch between routes in nearby regions. If pages open normally but large downloads are slow, inspect the destination itself. If every request intermittently stalls, packet loss, DNS, or the route deserves closer attention.

1. Disconnect and confirm that the local network can reliably reach commonly used sites on its own.
2. Reconnect to the current route and see whether the issue persists or affects only one app.
3. Switch to a node in a geographically closer location without changing the protocol or split-tunneling rules.
4. If UDP is unstable on the current network, compare it with an available configuration based on TCP or a TLS-like traffic profile.
5. Keep the error time, route name, client logs, and reproduction steps for further diagnosis.

Question 5: Does a VPN need to stay on all the time?

Not necessarily. Whether to keep it on depends on the network the device is using and the apps involved. On public networks, keeping the connection active can help when handling account logins or when consistent cross-border access is needed. On a trusted network used only for local services, disconnecting as needed may be appropriate. The point of always-on mode is not to keep an icon visible, but to ensure that traffic does not take an unexpected path after network changes, sleep, or wake-up.

Mobile devices frequently switch between Wi-Fi and mobile networks. During the transition, the old connection may fail and the client may need to rebuild the tunnel. If the app supports on-demand connections or reconnecting after network changes, enable those options according to the system permissions. On desktop devices, pay attention after waking from sleep: check the route status before resuming long downloads, remote sessions, or API requests.

When you need access to a printer, router admin page, or LAN storage, confirm that the client allows direct LAN access. If full-device routing does not correctly exclude local subnets, those devices may become temporarily unreachable. There is no need to disable all protection immediately; first check whether the split-tunneling rules include the LAN addresses.

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

These names refer to different proxy protocols or transport schemes; a “newer protocol” is not automatically faster. The client must support the protocol and transport parameters provided in the subscription. Otherwise, a node may appear in the list but still fail to connect. Check compatibility first, then consider how the current network handles TCP, UDP, and the relevant transport methods.

For beginners, the safest approach is to start with the default configuration supplied by the subscription and avoid manually changing authentication or transport fields. If the default route cannot connect, use the client log to determine whether the cause is DNS resolution, a handshake failure, a timeout, or unreachable UDP. The protocol name alone cannot replace an error message.

Question 7: How should I import and update a subscription link?

Copy the subscription link from the user panel, then look in the client for “Import from URL,” “Add subscription,” or a similarly named option. Paste it and run an update to fetch the node list. Button locations vary by platform, but the data flow is the same: save the subscription address, request the configuration, parse the nodes, and write them to the local list.

Windows, macOS, and Linux clients usually offer more complete routing, logging, and system-proxy options. iOS and Android rely on system-managed network interfaces, so the first connection may prompt you to create a VPN configuration. This system prompt means the client is requesting a virtual network interface; it does not confirm that the subscription succeeded. Return to the client to verify that nodes are present and complete the connection.

Import subscription
→ Update node list
→ Select a route
→ Establish connection
→ Check exit IP
→ Check DNS
→ Test the target app

When a subscription update fails, first check whether the link was truncated, especially for spaces or line breaks introduced during copying. If old nodes still connect but the update fails, the locally saved configuration may simply still be available; that does not mean the subscription address is currently reachable. Do not delete the only working configuration on impulse. Keep the current setup, then add the subscription again for comparison.

Question 8: What is the difference between IEPL, relay, and direct routes?

A direct route connects the client straight to an overseas node, keeping the path simple but making the result more directly dependent on cross-border public-network quality. A relay route first connects to a nearby entry point and then uses a relay network to reach the exit node, which can reduce uncertainty on parts of the public-network path. IEPL usually refers to an international Ethernet private-line connection provided by a carrier. Its cross-border segment does not use the ordinary public internet path, but the access point and the segment from the exit to the destination still need to be assessed against the actual network.

Route type is not the only factor. An entry point that is too far from the user, an exit too far from the target service, or congestion at the destination can all affect performance. Web browsing, streaming, remote work, and API calls also have different needs: browsing values first-byte response time, sustained transfers depend more on stable throughput, and interactive connections are especially sensitive to jitter and retransmissions.

74VPN offers 200+ routes across 90+ countries and regions. Start by narrowing the list to the area where the target service is located, then compare direct, relay, and private-line options. Do not infer the path from the region name alone; consider the node name, route description, and actual connectivity together.

Question 9: What is a DNS leak, and how should split-tunneling rules be configured?

Before reaching a domain, a device usually performs a DNS lookup to convert the domain name into a reachable address. If business traffic passes through the VPN while DNS requests still go to an unexpected local resolver, the lookup path and access path may diverge. This is commonly called a DNS leak. It can cause failed resolution, unsuitable regional addresses, or exposure of the resolver used by the local network.

Do not check only the exit IP. After connecting, also review the DNS test results and confirm that the resolution path matches the client settings. Encrypted DNS in the browser, the operating system’s DNS, the client’s built-in DNS, and DNS supplied by the router may all coexist. If the results conflict, keep one clear setup first, then enable other features one at a time.

Split tunneling determines which connections use the proxy and which connect directly. Common criteria include domains, address ranges, apps, and rule sets. Beginners can start with the service’s default rules: international services use the node, while local sites and LAN resources connect directly. If one app does not work as expected, check whether it bypasses the system proxy, uses its own DNS, or requires virtual network interface mode to be captured.

• ✅ Record the exit IP before and after connecting to confirm the address changes as expected.
• ✅ Check the DNS resolution results and confirm that an unexpected local resolution path is not still being used.
• ✅ Test a target app outside the browser so browser results are not mistaken for system-wide results.
• ✅ Confirm that LAN resources still connect directly according to the rules instead of being sent to a remote node.
• ❌ Do not enable multiple overlapping system-proxy, browser-proxy, and virtual-network-interface rule sets at the same time.

Question 10: What should I do if it says Connected but I still cannot access anything?

“Connected” usually means only that the client completed one connection stage. It does not guarantee that DNS resolution, route capture, and the target app are working. Break the diagnosis into parts: can the client reach the node, can DNS return a result, is system traffic entering the tunnel, does the destination accept the current exit, and is one app bypassing the proxy?

Test several different types of destinations first so an outage at one site is not mistaken for a route-wide failure. Then check the exit IP. If it has not changed, focus on the system proxy, virtual network interface, and split-tunneling mode. If it has changed but domains do not open, focus on DNS. If web pages work but a specific program does not, check whether that program uses an independent network stack, a fixed address, or ignores the system proxy.

1. Confirm that the local network works normally when the VPN is disconnected.
2. Update the subscription and verify that the current node still exists instead of relying on an expired local cache.
3. Review the client log for resolution, connection, handshake, and timeout details.
4. Switch to another route in the same region while keeping the protocol and split-tunneling settings unchanged.
5. Check the exit IP and DNS, then test the browser and target app separately.
6. If the cause remains unclear, submit a support ticket with the system version, client name, route name, error time, and reproduction steps.

Troubleshooting records should not include the complete subscription link, password, or authentication parameters. Mask account identifiers and node credentials before taking screenshots. Logs can retain error types and their sequence, but still check them for sensitive configuration before sending.

If you are simply getting started, begin with the default route and default split tunneling, then optimize after confirming the basic connection works. 74VPN supports unlimited devices and offers a 30-day no-questions-asked refund. Route selection, client settings, and troubleshooting records should all reflect the actual use case rather than the state of the connection button alone.
