Running a VPN on your router protects every device in your home — smart TVs, games consoles, IoT sensors, and anything else that cannot install a VPN app — under a single encrypted tunnel. The key factors are router firmware compatibility, protocol support at the hardware level, and the quality of the provider's setup documentation.
About: routers
Running a VPN on the router covers every device on the network, including ones that cannot run a VPN app themselves (smart TVs, consoles, IoT). What matters is supported firmware (DD-WRT, Tomato, AsusWRT or the provider's own), the protocols available at the router level, the number of simultaneous connections it frees up, and whether the provider documents the setup. We compare on verifiable facts and never publish router-throughput numbers we have not measured.

No VPN is confirmed for this use case yet. We list a provider here only once we have verified it fits — and joined its program.
Why put a VPN on your router?
A VPN installed on your router sits upstream of every device that connects to it. That means a smart TV, a PlayStation or Xbox, a security camera, a smart thermostat, or a guest's phone all benefit from the encrypted tunnel without any software installed on the device itself. For households with a large number of connected devices, this is the most complete coverage model available — nothing slips through because it lacks an operating system that supports the provider's client.
Router-level deployment also sidesteps simultaneous-connection limits entirely. Instead of counting individual device licences, you consume a single connection from the router's perspective; every downstream device on that network is simply traffic on that one connection. For families or shared households, this can represent meaningful practical value. It also simplifies management: one server selection, one set of credentials, one point of configuration — rather than maintaining clients across a dozen devices individually.
Technical criteria: firmware, protocols, and documentation
Router VPN support hinges on firmware. The major open firmware options — DD-WRT, Tomato, and AsusWRT-Merlin — all support OpenVPN natively, and AsusWRT-Merlin has added WireGuard support in recent versions. Some providers publish their own dedicated router firmware or offer a router app that layers on top of supported hardware, which can simplify configuration significantly. The critical question to ask before choosing a provider is: does it publish clear, maintained, step-by-step documentation specifically for the router firmware or hardware you own? Providers that treat router setup as an afterthought tend to have documentation that lags their desktop clients by months.
At the protocol level, OpenVPN is the most universally supported option across third-party firmware, but WireGuard is increasingly available and offers a lighter cryptographic footprint on router hardware — meaningful on lower-powered devices where OpenVPN can saturate the CPU. Of the audited providers, NordVPN (Panama, outside 14 Eyes, Deloitte audit Dec 2025), ExpressVPN (British Virgin Islands, RAM-only TrustedServer architecture, Kape Technologies), Surfshark (Netherlands, SecuRing infrastructure audit Jan 2026, Nord Security group), and Proton VPN (Switzerland, non-profit Proton Foundation majority owner, five consecutive annual audits) all publish router-specific setup guides. Mullvad (Sweden, open-source stack, no affiliate programme, anonymous account numbers) supports WireGuard and publishes configuration files suitable for manual router setup. Always verify the current documentation for your specific firmware version — this area moves quickly.
Trade-offs: who should — and shouldn't — use a router VPN
The router approach comes with real limitations. Because the VPN runs at the network layer rather than the device layer, you lose the per-device granularity that desktop and mobile clients provide. There is no kill switch on individual devices — if the tunnel drops, traffic from every connected device may leak until the router re-establishes the connection, depending on how the firmware handles the failure. Switching VPN servers requires logging into the router's admin interface rather than tapping a button in an app, which makes it impractical for users who regularly change exit locations. Split tunnelling — routing some apps through the VPN and others direct — is either unavailable or requires router-level configuration that can be technically demanding.
Router VPN setup suits households that primarily want passive, always-on privacy for IoT and media devices, and where the family's technical administrator is comfortable with router admin interfaces. It is less suited to individuals who need to switch countries frequently, rely on a kill switch for sensitive work, or want different devices on different servers simultaneously. A practical middle ground is to pair a router VPN for background devices with a standard client for the laptop or phone where granular control matters. Consider starting with a provider that offers dedicated router support or official firmware to reduce the configuration burden.
Frequently asked questions
What is the best VPN for a router in 2026?
There is no single answer that fits every router, but the providers with verified privacy credentials and documented router support worth evaluating include NordVPN (Panama, Deloitte-audited no-logs, Dec 2025), ExpressVPN (British Virgin Islands, RAM-only TrustedServer, owned by Kape Technologies), Surfshark (Netherlands, Nord Security group, SecuRing infrastructure audit Jan 2026), and Proton VPN (Switzerland, open-source apps, non-profit majority ownership, five consecutive annual no-logs audits). Mullvad (Sweden, open-source, no affiliate programme) is worth considering if you prefer anonymous account numbers and are comfortable with manual WireGuard configuration. The right choice depends on your router's firmware, whether you want a dedicated router app or manual configuration, and how often you need to switch servers.
Can any VPN be installed on a router?
No — only routers running firmware that supports VPN client mode can be configured this way. Most consumer routers shipped by ISPs do not support this out of the box. Routers running DD-WRT, Tomato, or AsusWRT-Merlin firmware generally support OpenVPN client mode, and AsusWRT-Merlin supports WireGuard. Some providers also publish their own router firmware or companion apps for specific hardware models, which can make setup more accessible. Before purchasing a VPN subscription with router use in mind, confirm that your router's make, model, and firmware version appear in the provider's router setup documentation.
Does a router VPN slow down my whole network?
Yes, to some degree, and the impact is felt across every device on the network since all traffic passes through the encrypted tunnel. The practical effect depends on your router's processor, the VPN protocol in use, and your baseline connection speed. OpenVPN is CPU-intensive and can be a bottleneck on older or lower-powered routers. WireGuard has a lighter cryptographic footprint and tends to perform better on the same hardware. Higher-end routers — particularly those with hardware AES acceleration — handle the encryption workload more comfortably. If throughput is a priority, check whether your router supports hardware-accelerated encryption before committing to a router-level deployment, and test with WireGuard where the provider supports it.
