Surfshark and EdgeRouter compatibility: what you need to know

EdgeRouter devices the EdgeRouter X, EdgeRouter 4, 6, and higher-end models run EdgeOS, a Linux-based firmware that gives you a lot of control with a fairly straightforward CLI. Surfshark, like most modern VPN providers, offers multiple ways to connect to its network, including OpenVPN and WireGuard. Here’s what that means for you:

OpenVPN compatibility: Surfshark provides OpenVPN configuration files you can use on many routers, including EdgeRouter. This is the most universally supported route across older EdgeOS builds and devices.
WireGuard compatibility: Surfshark has WireGuard support on many platforms. If your EdgeRouter firmware supports WireGuard via EdgeOS version with WireGuard package, you can achieve faster throughput and lower latency with a modern VPN protocol.
Kill switch and DNS: If you configure Surfshark on EdgeRouter correctly, all devices behind the router route through Surfshark, giving you a router-level kill switch, DNS leak protection, and centralized policy management.
Privacy at the router: A VPN-enabled EdgeRouter means every wired/wireless device uses VPN without needing individual app installations—handy for guests, smart TVs, gaming consoles, and IoT devices.

Why this matters in real life:

A typical home with multiple devices can save you the trouble of configuring 8–12 apps. One centralized VPN reduces friction, especially for family usage phones, tablets, consoles, and smart devices.
EdgeRouter hardware is known for stable performance under moderate loads, and Surfshark’s globally distributed servers help you pick nearby exit nodes to cut latency.
If you’re a streaming or gaming household, you’ll want to test speeds with and without VPN, because VPNs can reduce throughput by 10–40% depending on server, protocol, and distance.

Prerequisites: what you’ll need before you start

A Ubiquiti EdgeRouter X, X S, 4, 6, or any model that runs EdgeOS with VPN support
A Surfshark account with access to manual OpenVPN and/or WireGuard configuration files
A computer or laptop on the same LAN for initial setup, plus SSH access enabled on the EdgeRouter
Basic networking knowledge LAN, WAN, DNS, firewall rules, and NAT
Optional but recommended: a test device to verify VPN connectivity laptop or desktop

What you’ll configure:

One VPN tunnel OpenVPN or WireGuard that routes all LAN traffic
A safe DNS setup to avoid leaks
A basic firewall policy that acts as a kill switch block non-VPN traffic if the VPN goes down

Common pitfalls:

VPN interface naming and routing can be finicky on EdgeOS. Expect to adjust interface names e.g., tun0, vtun0, or similar to what your config uses.
DNS leaks happen if VPN DNS isn’t set as the primary resolver. You’ll want to force Surfshark DNS on your EdgeRouter.
If you’re on a slower connection or a distant server, OpenVPN tends to be more stable than WireGuard on older EdgeOS builds, while WireGuard can offer better speeds on newer hardware and firmware.

Step-by-step setup: getting Surfshark on EdgeRouter OpenVPN path

This path covers a reliable OpenVPN setup, which works on most EdgeRouter models and EdgeOS versions. If you have EdgeOS that supports WireGuard and Surfshark provides a config, you can try WireGuard as an alternative later. Pia extension chrome

Prepare your Surfshark OpenVPN credentials

Log in to Surfshark, go to the VPN section, find the manual setup area, and choose OpenVPN.
Pick UDP or TCP and a nearby server. Download the OpenVPN configuration file .ovpn or copy the required server address, port, and the certificate authority data.
Note your Surfshark username and password for the OpenVPN login these are usually generated in your Surfshark account under Manual Configuration.

Access EdgeRouter and enable SSH

Connect your computer to the EdgeRouter via LAN.
Open your SSH client and connect to the EdgeRouter’s IP commonly 192.168.1.1.
Log in with the admin credentials you use for the EdgeRouter.

Create a dedicated VPN interface on EdgeRouter

You’re creating a new VPN interface often named something like vtun0 or tun0 that Surfshark will use.
You’ll configure the interface with the OpenVPN config data server address, port, protocol, CA certificate, and TLS auth if applicable.

Configure the VPN tunnel

Input the OpenVPN details on EdgeRouter. This may involve:
- Setting the VPN interface as a client
- Providing the server address and port
- Supplying the VPN protocol UDP/TCP
- Inserting the CA certificate and TLS parameters from Surfshark
- Providing the Surfshark username and password for authentication
Ensure the VPN interface is brought up and has an IP address assigned by Surfshark’s server.

Route LAN traffic through the VPN tunnel

Create a routing rule so that traffic from your LAN e.g., 192.168.1.0/24 goes through the VPN interface.
Add a static route or policy-based routing, depending on EdgeOS capabilities, to ensure default gateway traffic uses the VPN tunnel.

Enforce a VPN kill switch

Add firewall rules to drop any device trying to access the internet if the VPN tunnel is down.
A typical approach is: if VPN interface is down, block LAN-to-WAN traffic and only permit VPN-related traffic.

Set DNS to Surfshark’s DNS

Point your router’s DNS to Surfshark DNS servers to prevent DNS leaks.
Example DNS Surfshark: 195.154.100.123 and 195.154.106.123 note: verify current DNS values in Surfshark’s docs

Test the setup

Reboot the EdgeRouter or restart the VPN service.
From a connected device, visit a site like ipchicken.com or whatsmyip.org to confirm you’re exiting from Surfshark’s server.
Run a DNS leak test to ensure queries aren’t leaking to your ISP’s DNS.
Check latency and throughput to the chosen Surfshark server to ensure performance is acceptable.

Optional: set up multiple VPN profiles

If you want to separate devices by VPN server or protocol, you can add additional OpenVPN interfaces and corresponding routing policies.

Notes and tips:

If you encounter authentication issues, double-check your Surfshark username/password and the OpenVPN config’s certificate data.
If you see “TLS handshake failed” errors, try a different Surfshark server or switch to UDP if you’re on TCP, as some servers perform better on different protocols.
Keep your EdgeRouter firmware up to date to ensure VPN compatibility and improved security.

Step-by-step setup: WireGuard if your EdgeOS supports it

If your EdgeOS version supports WireGuard and Surfshark provides a WireGuard module/config, wires can be simpler and faster. Here’s a high-level outline:

Generate WireGuard keys and install the WireGuard package on EdgeRouter if not already present
In Surfshark, generate a WireGuard configuration for a specific server, and copy the public key, endpoint, allowed IPs, and pre-shared key if provided
Create a WireGuard interface on EdgeRouter and input the keys and endpoint
Add peer configuration to EdgeRouter with Surfshark’s public key and allowed IPs
Route all LAN traffic through the WireGuard interface and configure a VPN kill switch
Point DNS to Surfshark’s DNS servers to prevent leaks
Test with speed tests and leak tests

Important: WireGuard setup can vary based on EdgeOS version and WireGuard package availability. If you’re unsure, start with OpenVPN the more widely supported path and move to WireGuard only if you’re comfortable with EdgeOS CLI changes.

Performance, reliability, and best practices

Speed expectations: VPN overhead typically ranges from 5% to 40% depending on server distance, protocol, and encryption. If you’re on a high-speed connection 500 Mbps+, WireGuard tends to yield better real-world throughput than OpenVPN in many scenarios. However, OpenVPN is widely compatible and stable across older EdgeOS builds.
Latency and gaming: Proximity to Surfshark’s edge servers matters. For latency-sensitive tasks, pick a server geographically close to you, and consider testing a few options to find the best balance of speed and stability.
Privacy: Surfshark doesn’t log user activity beyond what’s necessary to maintain service as per their privacy policy. When you route traffic through EdgeRouter, all devices on the LAN inherit this privacy layer, including guest devices and IoT gear.
DNS handling: Always enforce VPN DNS on EdgeRouter. If you don’t, DNS requests can leak and reveal your browsing history to your ISP or local network administrator.
Updates: Regularly update EdgeRouter firmware and Surfshark credentials. If Surfshark rotates credentials, update them on EdgeRouter promptly to avoid disruption.
Backup plan: If the VPN tunnel drops too often on OpenVPN, consider a lighter router config or a separate VPN-enabled device for critical tasks e.g., a dedicated streaming box or a second router.

Common issues and troubleshooting tips

VPN tunnel won’t come up:
- Re-check server address, port, protocol, and certificate data from Surfshark.
- Ensure EdgeRouter uptime doesn’t have a firewall rule blocking the VPN interface.
DNS leaks detected:
- Confirm the router is using Surfshark DNS and that DNS requests don’t bypass the VPN due to a misconfigured interface.
Slow speeds:
- Change to a closer server, switch to UDP if currently on TCP, or try WireGuard if your hardware supports it.
Devices won’t route through VPN:
- Verify your static routes or policy-based routing. ensure LAN networks use the VPN interface as the default gateway.
- Check the kill switch rules to ensure nothing else is allowing direct WAN access when VPN is down.
VPN disconnects under load:
- Check router CPU/RAM usage. high-load scenarios on older EdgeRouters can destabilize VPN tunnels. Consider upgrading or balancing load across multiple devices.
