If you’ve ever wished every gadget in your home could quietly benefit from a VPN without you installing yet another app, running Surfshark on your router is how you get there. But it’s also one of those projects that rewards preparation and punishes guesswork, so it’s worth walking through it step by step.
Why put Surfshark on your router at all?
When you install Surfshark on a router, you’re essentially moving the VPN “brain” from individual devices to the gateway that all traffic passes through. That has some very real upsides – and a few trade‑offs you should accept upfront.
What you gain
- Every device on your Wi‑Fi is covered: phones, laptops, smart TVs, consoles, even that weird smart fridge that can’t run apps.
- You don’t have to worry about installing or updating VPN apps on each device – once the router is set, the whole network rides through the tunnel.
- Devices that normally can’t use a VPN (older TVs, some set‑top boxes, consoles) get VPN protection simply by connecting to your Wi‑Fi.
What you give up
- You lose most of Surfshark’s app‑level features: things like CleanWeb ad blocking, smart split‑tunneling, quick protocol switching and easy server hopping are limited or missing at router level.
- Management is clunkier: changing locations means logging into your router’s admin panel instead of tapping a big connect button on your phone.
- Speeds can drop: consumer routers often have weaker CPUs, and encrypting all traffic 24/7 can expose the bottleneck.
- You need compatible hardware: the router firmware must support an OpenVPN, WireGuard or L2TP client (Surfshark’s focus is OpenVPN and WireGuard).
Even Surfshark itself gently nudges most people toward using apps on phones and laptops, and reserving the router setup for homes where “set it once and forget it” across many devices really matters.
Step 1: Check if your router can actually do this
Before you touch any settings, you need to know whether your existing router can run a VPN client. This is the make‑or‑break step.
Quick ways to check compatibility
- Read the user manual (or PDF): look for sections mentioning “VPN client,” “OpenVPN,” “WireGuard,” or “L2TP client.”
- Google your exact model number + “VPN client” or “OpenVPN”; chances are someone has already tried.
- Log in to the router:
- Find its IP (often
192.168.0.1or192.168.1.1) via your device’s network settings or using guides for “how to find your router’s IP address.” - Type that IP into a browser, sign in to the admin page, and look for a VPN, VPN client, or Advanced > VPN section.
- Find its IP (often
- Check Surfshark’s router help section: they maintain model‑specific guides for AsusWRT, DD‑WRT, GL.iNet, OpenWRT and others.
If you see options to configure OpenVPN or WireGuard as a client, you’re in business. If your router only mentions “VPN passthrough,” that’s not enough – that’s about forwarding VPN traffic, not originating it.
Step 2: If your router isn’t compatible, decide your hardware strategy
This is where many people hit a wall: their ISP‑supplied router simply doesn’t support running a VPN client. You have three realistic paths.
Option 1: Flash custom firmware (advanced, risky)
You can install open‑source firmware like DD‑WRT or Tomato on some routers to add VPN support.
- Upside: powerful features, granular control over VPN, routing and Wi‑Fi.
- Downside: if you flash the wrong build or follow the wrong instructions, you can permanently brick the router and may void your warranty.
If you go this route, use the official compatibility lists and model‑specific flashing instructions – and read them twice before you click “upgrade.”
Option 2: Buy a VPN‑friendly router
This is the easier, more “consumer‑friendly” approach.
Common recommendations include:
- Asus routers with AsusWRT firmware – such as RT‑AC68U, RT‑AC86U, RT‑AC88U, RT‑AC3200, RT‑AC5300 and similar models, which have built‑in OpenVPN client and newer “VPN Fusion” features.
- GL.iNet travel/mini‑routers – models like GL‑AR750S (Slate), GL‑MT300N‑V2 (Mango) or GL‑AR300M (Shadow) ship with OpenWRT and an OpenVPN/WireGuard client pre‑installed.
- Many TP‑Link and similar routers now offer WireGuard/OpenVPN client options, sometimes with vendor guides specifically for Surfshark.
You can run one of these behind your ISP modem/router in “bridge” or “double NAT” mode, with the new box handling the VPN.
Option 3: Keep router as‑is, stick to apps
If you only care about a handful of devices (say, just your phone and laptop), apps may still be simpler: you get all Surfshark features and better performance, with far less tinkering.
Step 3: Get your Surfshark credentials and config files
Once you have a VPN‑capable router, you’ll need the configuration data from Surfshark – this is what the router uses to connect to their servers.
Typical checklist:
- An active Surfshark subscription.
- Access to your Surfshark account dashboard in a browser.
- A choice of protocol: OpenVPN (widely supported) or WireGuard (usually faster and simpler on newer routers).
The usual flow (it’s very similar across firmware types):
- Log in to your Surfshark account on the web.
- Go to the VPN section, then “Manual setup” and choose “Router.”
- Select the protocol (OpenVPN or WireGuard) and region/location you want your router to connect to.
- Download the config file(s):
Keep those files handy – you’ll be uploading or copy‑pasting from them into your router interface.
Step 4: The generic setup flow on most routers
The details vary between AsusWRT, DD‑WRT, GL.iNet, TP‑Link and others, but the high‑level flow is surprisingly similar.
1. Log in to your router’s admin panel
- Connect to your home network.
- Type the router’s IP (e.g.,
192.168.1.1) into a browser. - Sign in with the admin username and password (change defaults if you’ve never done that – security 101).
2. Find the VPN client section
You’re looking for options like:
- “VPN” > “VPN Client” or “VPN Fusion” (Asus).
- “Services” > “VPN” (DD‑WRT).
- A dedicated “VPN” tab (GL.iNet, some TP‑Link models).
3. Create a new VPN profile
Most interfaces ask for:
- A connection name (e.g., “Surfshark‑UK” or “Surfshark‑WireGuard”).
- VPN type/protocol (OpenVPN, WireGuard).
- Server details, credentials and keys – imported from the Surfshark config files you downloaded.
For OpenVPN profiles, you will typically:
- Upload the .ovpn file directly, or paste the server address and certificates from its contents.
- Enter your Surfshark service username/password if required (these may be different from your account email/password – Surfshark generates them for manual setups).
For WireGuard profiles (on newer AsusWRT/Asus VPN Fusion and some others):
- Choose Surfshark as the VPN type, paste the private key from your Surfshark WireGuard config, and pick the region.
- Bind the profile to specific devices or to all devices, depending on what the firmware lets you do.
4. Save and enable the connection
- Hit Save/Apply.
- Toggle the profile on or choose “Activate” / “Enable.”
- Some routers let you mark it as the default connection for all devices; others let you assign it per‑device or per‑SSID.
Once connected, the router will route all selected devices’ traffic through Surfshark.
Step 5: Model‑specific examples (Asus, DD‑WRT, GL.iNet, TP‑Link)
To make this less abstract, here’s how it looks on some popular platforms.
Asus routers (AsusWRT / VPN Fusion)
Asus is a common choice because its consumer routers ship with a friendly GUI and a built‑in VPN client.
- In classic AsusWRT: you go to VPN > VPN Client, add a new OpenVPN profile, upload the Surfshark .ovpn file, then connect.
- In newer firmware with VPN Fusion: you add a profile, select Surfshark as the VPN type, paste in the private key from the Surfshark WireGuard section, choose a region, then bind devices and enable.
DD‑WRT routers
DD‑WRT is powerful but not exactly hand‑holding. Once installed on a compatible router:
- You enable the OpenVPN client in Services > VPN, then copy in server addresses, ports, encryption settings and certificates from your .ovpn file.
- The upside: deep control and flexibility. The downside: it’s easy to mess something up if you’re not comfortable with networking terms.
GL.iNet mini routers
GL.iNet routers are a sweet spot if you want power without the pain of flashing firmware.
- They ship with an OpenWRT‑based interface and built‑in OpenVPN/WireGuard clients, plus quick wizards for importing .ovpn or WireGuard configs.
- You essentially plug one into your existing network, log into its admin page, import your Surfshark files, and decide whether it runs as your main router or a dedicated “VPN Wi‑Fi” for specific devices.
TP‑Link (and similar) routers
Some TP‑Link models include guides for Surfshark specifically.
- The flow is similar: log in, go to VPN client settings, pick WireGuard or OpenVPN, then either upload or manually enter Surfshark config details.
Whenever you’re unsure, Surfshark’s own router section has model‑specific guides that are worth following line by line.
Step 6: Test and fine‑tune your VPN router
Once the router says “connected,” you still want to confirm it’s actually doing what you expect.
Basic checks
- On any device using that Wi‑Fi, visit an IP‑checking site and confirm your IP/location matches the Surfshark server you selected.
- Try accessing a geo‑restricted service (like a streaming catalog in the chosen country) to see if it behaves as expected.
Performance and routing tweaks
- If speeds are poor, try:
- Switching to a server physically closer to you.
- Using WireGuard instead of OpenVPN where supported, as it’s generally more efficient.
- Moving bandwidth‑heavy or latency‑sensitive apps (like competitive gaming) off the VPN, either via per‑device policies or by using a non‑VPN SSID if your router supports it.
- Keep in mind that, unlike app‑based split tunneling, router‑level split options are limited and vary by firmware. Some (like Asus VPN Fusion) let you assign devices to VPN or non‑VPN paths; others are all‑or‑nothing.
Also, remember that if the VPN tunnel drops at the router, every connected device instantly loses VPN protection – so it’s worth checking that the router reconnects automatically.
When a VPN router is worth it – and when it isn’t
Putting Surfshark on your router makes most sense if:
- You have a house full of devices and don’t want to babysit VPN apps on each of them.
- You care about protecting “dumb” or semi‑smart gear that can’t run a VPN app.
- You’re comfortable logging into a router’s admin page now and then to tweak things.
It’s less compelling if:
- You mostly use one or two personal devices and love Surfshark’s app‑based extras.
- You need maximum speed on a mediocre router CPU.
- You regularly switch locations and don’t want to dive into router settings just to watch a different streaming library.
The good news: you don’t have to pick one forever. Many people run Surfshark on their router for baseline coverage and still keep the apps on a few key devices for extra control when they need it.
