Two main routes to a Surfshark-enabled router

OpenVPN-based setup the most compatible, widely supported

Works on most firmware that supports VPN clients: Asuswrt-Merlin, DD-WRT, OpenWrt, Merlin-based builds
Gives you solid security, good compatibility, and straightforward server selection

WireGuard-based setup fastest, increasingly popular on modern hardware

If your router’s firmware supports WireGuard and Surfshark offers a WireGuard configuration, you can push higher speeds with strong security
Not every older router or firmware version supports WireGuard well. plan for hardware requirements if you go this route

Key prerequisites and tips

Router choice matters: aim for a router with decent CPU power and enough memory at least 128–256 MB RAM and a dual-core CPU is a safe starting point. If you’re gaming or streaming in 4K, more headroom helps.
Firmware matters: use firmware that supports VPN client mode Asuswrt-Merlin is a popular choice. DD-WRT and OpenWrt are solid options as well.
Surfshark plan with unlimited devices is a big win for a router setup, since every device on your network automatically benefits without configuring each one individually.
Privacy and security: Surfshark supports AES-256 encryption, multiple protocols including OpenVPN and WireGuard, a no-logs policy audited by Cure53 in 2022, and features like a kill switch and DNS leak protection. These features translate into real-world protection for your entire home network.
Server selection matters for speed: pick a server geographically close to you or one with a fast performance track record. For streaming and gaming, you may want servers optimized for streaming or with lower latency.

Router compatibility and firmware overview

Asuswrt-Merlin popular choice: Great for OpenVPN and WireGuard setups. straightforward UI for VPN client configurations
DD-WRT: Very flexible, strong OpenVPN support. some older models may struggle with high-speed VPN
OpenWrt: Extremely flexible, good for power users. can be more complex to configure but offers excellent control
Netgear and Linksys: Some models support built-in VPN client modes, but you’ll often get easier setup with Asuswrt-Merlin or DD-WRT/OpenWrt on supported hardware
Firmware upgrade caveat: flashing new firmware can void warranties and, if done incorrectly, brick a router. Always follow vendor and firmware-community guides, backup configs, and have a recovery plan.

Path A: OpenVPN-based router setup best starting point
Overview

OpenVPN is the most universal option across routers and firmware
You’ll download an OpenVPN profile from Surfshark, copy credentials, and import into your router’s VPN client interface

Step-by-step: Asuswrt-Merlin example

Prepare the router

Confirm your router model supports VPN client mode and that you have a backup of the current firmware
If you’re not already on Asuswrt-Merlin, you may need to flash a Merlin-based build or a compatible OpenWrt/DD-WRT version

Get Surfshark OpenVPN config

Log in to Surfshark, go to VPN > Manual Config > OpenVPN
Pick a server location, download the OpenVPN configuration file .ovpn, and note the login credentials username and password
If you’re using WireGuard later, you’ll also download WireGuard config here, but for OpenVPN use the .ovpn file

Configure the router’s VPN client

Access the router admin page usually 192.168.1.1 or 192.168.0.1
Open VPN client section for Asuswrt-Merlin: VPN -> VPN Client -> Add profile
Choose Import and upload the .ovpn file
Enter the Surfshark username and password when prompted
Make sure the VPN is set to start with the router auto-start on boot and that the interface is enabled

DNS and leak protection

In the VPN settings, set DNS to a trusted resolver e.g., 1.1.1.1 or 9.9.9.9 or enable Surfshark DNS if offered
Enable DNS leak protection and, if available, “kill switch” to block traffic if the VPN drops

Save, apply, and test

Apply the settings and wait for the VPN to connect
Check the router status page to confirm a VPN IP assigned to the router interface
From a connected device, visit a site like whatismyip.com to confirm the location and that the IP belongs to Surfshark’s network

Verify all devices are protected

Ensure devices are using the router’s VPN by checking their IP addresses
If some devices bypass the VPN, re-check split tunneling settings or device-level configurations

Step-by-step: DD-WRT/OpenWrt alternative firmware

In DD-WRT/OpenWrt, you’ll similarly import the OpenVPN profile, provide the credentials, and customize the VPN client settings
DD-WRT: Services > VPN > OpenVPN. Upload config. set user/pass. enable Start with WAN
OpenWrt: Use luci-app-openvpn or opkg install openvpn and configure an OpenVPN client with the .ovpn data. ensure DNS settings propagate
Consider enabling a firewall rule to ensure all traffic goes through VPN and turning on the built-in kill switch feature if your firmware provides it

Path B: WireGuard-based router setup speed-focused

If your router has robust CPU and your firmware supports WireGuard, this is typically the fastest option with Surfshark
You’ll need a WireGuard configuration from Surfshark and a compatible WireGuard client on the router
WireGuard tends to be simpler in terms of network rules and often yields lower latency

Step-by-step: general WireGuard setup

Validate hardware and firmware

Confirm your router’s firmware supports WireGuard, and that you can import a WireGuard config
Ensure you’re running the latest stable firmware for performance and security improvements

Retrieve WireGuard config from Surfshark

In Surfshark, go to VPN > Manual Config > WireGuard if available or contact Surfshark support for the latest WireGuard config options
Copy the private key, public key, endpoint, and allowed IPs as provided

Configure the router

In your router’s WireGuard section, add a new peer or interface
Paste in the keys, set the allowed IPs usually 0.0.0.0/0 for full-tunnel, and use the correct endpoint
Save and enable the connection

DNS and security

Route DNS queries through the VPN or set a trusted DNS 1.1.1.1, 9.9.9.9
Enable the router’s kill switch if available to block traffic if the tunnel drops

Test and verify

Check IP via whatismyip.com and ensure it shows Surfshark’s endpoint
Run a quick speed test to see the improvements or changes in latency

Common issues and fixes quick-reference

VPN not connecting: double-check credentials, server, and config file. ensure port forwarding isn’t blocked by the ISP
DNS leaks: confirm you’re using a VPN-provided DNS or set a private DNS in the router’s VPN settings
Kill switch not working: ensure the kill switch feature is enabled and configured to block non-VPN traffic
Slow speeds on VPN: try a nearby server, switch to WireGuard if possible, or reduce encryption overhead by selecting a faster protocol
Devices bypassing VPN: disable or reconfigure any split-tunneling rules on the router level or in device-level apps

Security, privacy, and performance best practices

Use a strong, unique router admin password and enable two-factor authentication on your Surfshark account
Regularly update router firmware and Surfshark app/configs to protect against vulnerabilities
Consider using separate guest networks for IoT devices. keep main devices on the VPN to maximize privacy
If you have smart home devices that don’t require VPN, consider network segmentation so they stay isolated
Periodically test for DNS leaks and IP leaks to ensure continued protection
For streaming, choose servers optimized for streaming or video quality and consider enabling “kill switch” to avoid accidental exposure if the VPN disconnects

Testing and verification: how to confirm you’re protected

IP address test: visit whatismyip.com from a connected device. confirm the IP matches Surfshark’s location
DNS leak test: run a DNS leak test search “DNS leak test” and use a reputable tool to ensure your DNS queries are not leaking to your ISP
Speed test: run a baseline speed test without VPN and compare to VPN-enabled results for a rough speed delta
Streaming and gaming: test streaming apps to confirm access to geo-restricted content and check online gaming latency when connected to a local server

Quick-start checklist

Confirm router supports VPN client mode and choose the firmware Asuswrt-Merlin, DD-WRT, or OpenWrt
Have Surfshark login credentials ready and the OpenVPN or WireGuard config downloaded
Decide on OpenVPN vs WireGuard based on your router’s capability and your speed needs
Back up current router settings before flashing or changing firmware
Import OpenVPN or WireGuard configuration into the router, enter credentials, and enable auto-start
Configure DNS and enable kill switch if available
Connect a device and test the VPN on the router network
Keep a spare plan for fallback if the VPN introduces instability

Why router-level VPN is worth it

Unified protection: Every device on your network is covered, including smart TVs, consoles, and IoT devices that don’t have VPN software
Easier management: One central configuration rather than installing separate VPN apps on dozens of devices
Consistent privacy: You control which network traffic goes through the VPN and reduce the risk of device-level misconfigurations

Common mistakes to avoid

Skipping backups: Always backup the current router config before flashing or changing firmware
Using low-performance hardware: Some older routers struggle with VPN encryption. invest in a more capable model if you’re serious about speed
Not testing: Skipping IP/DNS leak tests can leave you exposed even when the VPN is “connected”
Ignoring firmware updates: Outdated firmware can introduce vulnerabilities or performance issues
