• Import and configure on EdgeRouter
• Test for leaks and performance
• Tweak for best balance of speed and security

we’ll also discuss how EdgeRouter handles VPN traffic at the network edge, what to expect in terms of speeds, and how to maintain a stable connection across all devices. For those who want a broader VPN option, there’s the NordVPN deal above — it’s a good way to compare features if you’re evaluating multiple vendors.

Prerequisites and basics you need before you start

• An EdgeRouter device running EdgeOS ER-X, ER-12, ER-6P, or newer with a stable firmware release
• A Surfshark account and access to either OpenVPN config files or WireGuard endpoints
• Basic network knowledge: LAN subnet, WAN interface, and how to access EdgeOS via the web UI or SSH
• A backup plan: know how to revert changes if something goes wrong keep a recovery plan handy
• Optional but recommended: a secondary device to test the VPN connection before rolling it out network-wide

EdgeRouter compatibility and what to expect

• OpenVPN on EdgeRouter: A reliable, widely supported option. Surfshark’s OpenVPN configs are typically available in UDP or TCP variants and allow you to route all traffic through the tunnel.
• WireGuard on EdgeRouter: Known for speed and a simpler key-management model. If your EdgeRouter firmware supports WireGuard, you can set up a UDP-based tunnel that’s generally faster and more stable in typical home network conditions.
• Caveats: Not all EdgeRouter models support every EdgeOS version’s VPN features out of the box. Always ensure you’re running a supported EdgeOS build and back up your current configuration before making changes. If you rely on certain firewall rules or DNS configurations, keep a copy of your current settings so you can restore them if the VPN setup disrupts normal traffic.

OpenVPN vs WireGuard on EdgeRouter: a quick comparison

• OpenVPN: Very compatible with Surfshark, broad support, robust identity verification, and straightforward split-tunneling rules via routing tables. It can be a bit slower than WireGuard due to its encryption overhead, but it’s very reliable on many networks.
• WireGuard: Ultra-fast on most hardware, simpler config with fewer moving parts, and excellent performance in typical home networks. Some ISPs or networks may have quirks with UDP-based VPN tunnels, so testing is key.

OpenVPN setup on EdgeRouter: step-by-step conceptual, with practical tips

1. Gather Surfshark OpenVPN config
   • Log in to Surfshark, download OpenVPN configuration files for your preferred server location UDP and/or TCP. You’ll typically have a .ovpn file plus CA certificate and possibly user credentials.
2. Prepare EdgeRouter for VPN client
   • Decide whether you’ll route all traffic through the VPN full-tunnel or use split tunneling only certain subnets go through the VPN. You’ll also plan your DNS handling to avoid leaks more on that below.
3. Import or recreate the OpenVPN client on EdgeRouter
   • Depending on your EdgeOS version, you may import the .ovpn file or configure an OpenVPN client profile using the GUI or CLI. The goal is to create a VPN interface tun0 or similar that connects to Surfshark’s server using the provided certificates and credentials.
4. Route and NAT setup
   • Ensure the VPN interface is part of the WAN routing path and that LAN devices route through the VPN tunnel. If you want split tunneling, create firewall rules and routing tables to selectively push traffic through the VPN.
5. DNS and leak prevention
   • Point your DNS to Surfshark’s DNS servers or a trusted DNS provider and block DNS queries outside the tunnel. This minimizes DNS leaks and helps ensure your queries stay within the VPN.
6. Test and verify
   • Check your new public IP from a connected device to confirm it matches the Surfshark server location. Run DNS leak tests. Test multiple devices to ensure consistent behavior.
7. Troubleshooting tips
   • If the VPN won’t connect, double-check server address, port, protocol UDP vs TCP, and authentication settings. Make sure there’s no conflicting firewall rule or another VPN on the same device.

WireGuard setup on EdgeRouter: step-by-step conceptual

1. Confirm WireGuard support on EdgeOS

   • Verify that your EdgeRouter firmware includes WireGuard capabilities. If not, you may need to upgrade EdgeOS or use a different router.

2. Obtain Surfshark WireGuard configuration

   • Surfshark provides WireGuard-compatible configuration data public keys, private keys, and endpoint details. You’ll need to paste these into EdgeRouter’s WireGuard configuration.

3. Create a WireGuard interface

   • On EdgeRouter, configure a WireGuard interface wg0 with a private key and the allowed IPs you want to send through the VPN typically 0.0.0.0/0 for full-tunnel.

4. Add a peer

   • Add Surfshark’s endpoint as a peer with the appropriate public key, endpoint address, and allowed-ips 0.0.0.0/0. Include a persistent keepalive if required for NAT traversal.

5. Routing and NAT

   • Route traffic from LAN toward the wg0 interface for VPN traffic. If you want split tunneling, set up routing rules so only selected subnets go through wg0.

6. DNS and leak considerations

   • Point DNS to Surfshark’s DNS or another trusted DNS, and ensure DNS queries go through the VPN to prevent leaks.

7. Verification

   • Similar to OpenVPN, verify your IP shows Surfshark’s server and run DNS leak tests to confirm you’re not leaking DNS requests.

8. Troubleshooting

   • If you can’t establish a peer connection, re-check public keys, endpoint IP/port, and MTU sizes. Disable conflicting VPN services and confirm firewall rules allow WireGuard traffic.

DNS, split tunneling, and kill switch on EdgeRouter

• DNS configuration: When you route all traffic through Surfshark, you want to ensure DNS queries do not leak. Configure EdgeRouter to use Surfshark’s DNS servers or a privacy-focused DNS provider e.g., 1.1.1.1 with DNS-over-TLS. You can also set DNS forwarding rules so that DNS requests from LAN always go through the VPN tunnel.
• Split tunneling: This lets you decide which devices or subnets use the VPN and which go directly through your regular ISP. Common patterns:
  • Full-tunnel: All traffic uses VPN
  • Selective-tunnel: Only devices like your laptops or streaming devices go through VPN. smart home devices stay on the standard ISP route
• Kill switch: Ensure that if the VPN tunnel drops, you can block traffic from your LAN to avoid traffic leaking outside the VPN. On EdgeRouter, you can implement firewall rules that block outbound traffic if the VPN interface is down, or route default traffic through the VPN with a fallback rule if needed.

Performance tips to keep Surfshark on EdgeRouter speedy

• Choose nearby Surfshark servers: Proximity reduces latency and improves speeds. If you’re gaming or streaming, pick servers that are geographically closer to you.
• Use WireGuard where supported: If your EdgeRouter hardware and firmware support WireGuard, you’ll often get better throughput and lower latency than with OpenVPN.
• Enable multi-core processing where available: Some EdgeRouter models handle VPN processing efficiently when you enable hardware acceleration features if your model supports it.
• Fine-tune MTU and fragmentation: VPN traffic can struggle with large packets. Start with a standard MTU 1500 and adjust downward in small increments if you notice packet loss or instability.
• Monitor CPU load: VPN encryption adds CPU load. If you have an older EdgeRouter, monitor CPU usage during peak times and consider moving to a Lite or more capable model if VPN performance is consistently slow.
• Regular updates: Keep EdgeOS and Surfshark configs up to date. Firmware updates can improve VPN compatibility and performance.

Testing and verifying VPN coverage on your network

• IP test: From a connected device, visit a site that shows your IP and location to verify you’re using Surfshark’s IP.
• DNS test: Use a DNS leak test site to confirm DNS queries are resolved by Surfshark’s servers and not by your ISP.
• Speed test: Run speed tests with VPN enabled and disabled to understand the performance impact. Note the difference and adjust server location accordingly.
• Kill switch test: Temporarily disconnect the VPN and make a simple request from a device to ensure traffic doesn’t go out through your real connection if the VPN drops.

Common issues and quick fixes

• VPN won’t connect: Double-check VPN server address, port, protocol, and credentials. Ensure the OpenVPN or WireGuard config matches what Surfshark provides for your chosen server.
• DNS leaks: Verify DNS settings and ensure DNS requests are handled by the VPN. If needed, add firewall rules to block DNS unless the VPN is active.
• Slow speeds: Try a different server, use WireGuard if available, adjust MTU, or check for network congestion during peak times.
• Connection drops: Check for firewall rules that might intermittently block the VPN interface. Reboot the EdgeRouter to refresh networking stacks and reattempt the VPN.
