Quick answer: choose the connection direction first
The best VPN for a Synology or QNAP NAS depends on the job. A commercial VPN client sends selected NAS internet traffic through a provider. A remote-access VPN lets an authorized person reach a private network. Buying the former does not automatically create the latter. ExpressVPN, NordVPN and Surfshark document manual NAS connection options, but the exact operating system, configuration and routing policy matter more than a generic fastest-VPN label.
This guide brings together the useful Synology and QNAP buying questions from older articles and replaces their obsolete figures and broad security promises. VPNBlade Editorial reviewed current manufacturer and provider documentation; we have not benchmarked these providers on a NAS. The offers use our existing subscription records and affiliate controls. Check compatibility before committing to a long subscription.
NAS VPN client versus remote-access VPN
| Requirement | Connection to investigate | Important boundary |
|---|---|---|
| Route NAS internet transfers through a provider | Supported VPN client profile on the NAS or its router | A changed exit address does not grant private inbound access. |
| Reach private files while away | An appropriately managed remote-access VPN | Decide who can reach which resources and how access is revoked. |
| Connect two private locations | A supported site-to-site or managed network design | A consumer subscription alone does not define routes or authorization. |
| Protect stored files and recover backups | Storage permissions, updates, encryption and a tested backup plan | A network tunnel does not replace these controls. |
For example, sending an automated upload through a commercial provider is an outbound-routing requirement. Letting a colleague open a private project folder from another location is an access-control requirement. Write down that distinction before looking at subscription prices. Our remote-access planning guide covers the second case in more detail.
Three commercial providers to compare for outbound NAS use
These are documented setup options, not measured NAS performance rankings. Keep the NAS workflow separate from features advertised for a provider’s Windows or mobile app. A manual profile does not automatically include the app’s kill switch, filters, protocol choices or interface.
ExpressVPN: consider its specific Synology OpenVPN instructions
ExpressVPN provides a Synology manual OpenVPN guide using account-supplied configuration files and setup credentials. Its documentation explicitly warns that manual configuration does not deliver the same privacy and security benefits as its apps, is not optimized for streaming, and does not offer every location. Those qualifications are more useful to a NAS buyer than transferring desktop-app marketing claims into a manual installation.
Reasons to consider it
- A device-specific manual setup route is documented
- The provider states important manual-configuration limitations
Trade-offs
- Manual setup is not equivalent to its native apps
- Available manual locations and intended use need checking
Choose it when: the documented Synology workflow matches your system and you accept its manual-mode limits. Check QNAP compatibility separately rather than copying Synology screens.
NordVPN: compare its imported OpenVPN profile workflow
NordVPN’s Synology support article covers DSM 6.1 and later and describes obtaining a server configuration and service credentials from Nord Account. The setup imports an OpenVPN profile into the NAS network interface. Match the documentation to your actual DSM release and obtain the credentials intended for manual connections; ordinary account sign-in details are not a substitute.
Reasons to consider it
- Configuration downloads and service credentials have a documented account route
- Its Synology article describes the profile-import workflow
Trade-offs
- Desktop NordLynx and other app features should not be assumed here
- Profile and certificate requirements must match the selected server
Choose it when: you want a documented OpenVPN import route and can verify the resulting traffic policy. An older tutorial’s instruction to select every option is not a reason to enable routing you do not need.
Surfshark: consider its current manual Synology setup
Surfshark’s Synology instructions describe generating manual setup credentials and downloading a location’s OpenVPN configuration. Its account credentials for this procedure differ from the email and password used for regular account sign-in. The guide separates its older DSM 6.2 instructions, which is a useful reminder to identify your system version before following screenshots.
Reasons to consider it
- Manual credentials and location profiles are documented
- Version-specific guidance helps identify the intended procedure
Trade-offs
- App-only controls cannot be inferred from a successful profile import
- NAS routing and reconnect behavior still need local verification
Choose it when: the supported manual route fits your NAS and the full subscription cost fits your wider device requirements. Compare the initial bill and renewal rather than assuming one headline monthly figure settles the choice.
Plan a Synology connection without copying outdated settings
Identify the NAS model, DSM version and current network arrangement first. Synology’s DSM 7.4 network specifications include OpenVPN profile import and specify one concurrent VPN connection. Check the specifications for your installed release rather than interpreting multiple saved profiles as multiple simultaneous tunnels. Do not assume a provider’s support for a protocol means the NAS has the corresponding client.
The broad OpenVPN workflow is to obtain the current provider profile, use its manual setup credentials, create a VPN network interface, import the required file and configure the intended route. Certificate and authentication requirements belong to that exact provider profile. Keep a record of the previous gateway and a local way to manage the NAS before making changes. We are describing the decision process, not supplying universal settings for every model.
Plan a QNAP connection around the actual QVPN version
QVPN Service has separate client and server functions. For outbound provider use, its client connection profiles are the relevant starting point. OpenVPN imports need a provider configuration file. Supported protocols vary with the QVPN release, firmware and hardware architecture, so check the compatibility matrix before expecting WireGuard or another option on a particular NAS.
QNAP also documents default-gateway and backup-connection behavior. Automatic reconnection or a gateway change after a failed connection should not be described as a verified fail-closed kill switch. Ask what traffic does during disconnection, not merely whether the connection eventually returns. Keep the test limited to a controlled task that can safely be interrupted.
Use a small acceptance checklist before trusting unattended transfers
- Record a working baseline for local administration, name resolution and the intended transfer.
- Identify whether the route applies to the NAS, selected workloads or other devices as well.
- Connect the supported profile and confirm the intended task uses the expected exit path.
- Check DNS and IPv6 handling against the exact platform and provider instructions.
- Observe a controlled disconnection and recovery; record what stops, continues or changes route.
- Repeat relevant checks after a reboot and before relying on unattended jobs.
A browser on your laptop can show a different route from a task running on the NAS. Test the workload and network namespace that matter. Our VPN verification guide explains why a connected indicator or changed public address is only part of the evidence. Never publish the NAS credentials or a private configuration file as a troubleshooting screenshot.
Decide whether the NAS or router should run the client
A NAS client can make the storage device’s route easier to distinguish from the rest of the household. A router client can place selected devices behind a shared policy, but that policy depends on the router’s capabilities and configuration. Neither arrangement automatically covers every container, virtual machine or other device. Confirm each required workload rather than treating physical connection to the same box as proof.
Our router buying guide and router setup checklist explain that alternative. Avoid stacking a NAS tunnel and router tunnel without a specific reason: it adds another layer to diagnose. Keep a supported baseline you can restore.
Measure the job instead of buying an unverified speed claim
For a nightly backup, the useful question is whether it finishes within its scheduled window and restores correctly. For a large upload, record transfer size, elapsed time, destination and the network conditions. Compare the ordinary route with one supported VPN route under reasonably similar conditions. Those observations describe your setup; they do not establish a universal winner across NAS models or providers.
The limiting factor may be storage, processor load, the remote service or the available uplink. A higher advertised internet speed does not identify that bottleneck. Avoid changing several settings at once, and do not disable unrelated protections to obtain a more flattering number. Preserve successful backup verification as a separate requirement from network throughput.
Keep remote file access and storage protection in scope
If the objective is remote access, define the permitted user, resource and removal process before opening connectivity. Review the supported remote-access design for your exact system. Do not expose an administration page to the internet simply because an older article mentions port forwarding. An outbound consumer VPN cannot replace authentication or decide which private folder a visitor may open.
Keep operating-system and package maintenance, account permissions and recoverable backups in the plan. A tunnel concerns a connection path; it does not repair a vulnerable application or recover an accidentally deleted file. For organization-managed devices, follow the administrator’s policy rather than improvising a second access route.
Common questions before paying
Can I use a free VPN on a NAS?
Check whether the particular free account permits manual profiles on your NAS, and compare its limits with the workload. A free download is not proof of a free service entitlement. Our free-plan guide explains the distinction. There is no basis for treating every free service as malicious or every paid service as automatically suitable.
Will a VPN stop NAS ransomware or protect every file?
No such conclusion follows from establishing a tunnel. File permissions, software exposure, account security and backup recovery remain separate concerns. Treat a provider connection as one deliberately scoped network choice, without promising that it prevents every compromise.
What should I compare in the deal?
Compare the full first payment, subscription term, renewal, purchase channel and the supported manual setup. Check cancellation and refund eligibility before relying on either. Start with compatibility and a controlled acceptance test; a longer discounted commitment is only useful when the service actually meets the requirement.
