  • Better security for guest networks

Prerequisites and Planning

• Hardware and firmware:
  • EdgeRouter X/4/Pro or newer
  • Latest EdgeOS firmware
  • A Surfshark subscription
• Networking plan:
  • Decide which devices should route through VPN all devices or only certain subnets
  • Choose VPN protocol WireGuard for speed; OpenVPN for compatibility
  • Plan DNS settings to prevent leaks use Surfshark DNS or a trusted DNS like Quad9
• Security baseline:
  • Change admin credentials on EdgeRouter
  • Disable unused services UPnP, SSH from WAN unless you need them
  • Create a separate VLAN or firewall rules for guest networks

Step-by-Step Setup Guide
Step 1: Prepare Surfshark and EdgeRouter

• Sign in to Surfshark and set up a VPN profile WireGuard recommended for performance. Download the configuration files if you’re using OpenVPN, or note the WireGuard server details.
• Access your EdgeRouter through its web UI https://192.168.1.1 or your custom IP.
• Create a backup of your current configuration before making changes.

Step 2: Create VPN Interfaces on EdgeRouter

• If using WireGuard:
  • Add a WireGuard interface under the EdgeRouter’s VPN settings.
  • Enter the private key provided by Surfshark’s WireGuard config and the peer Surfshark server public key and endpoint.
  • Assign a local IP subnet for the VPN for example, 10.14.0.0/24.
• If using OpenVPN:
  • Create an OpenVPN interface and import the .ovpn file from Surfshark.
  • Ensure the interface gets an IP address from the VPN tunnel.

Step 3: Routing and NAT

• Route all or selected traffic through the VPN interface:
  • For full-device VPN: set a default route via the VPN interface.
  • For selective VPN: create policy-based routing PBR rules to send specific subnets or IP ranges through the VPN.
• Set up NAT masquerading for the VPN interface so outbound traffic appears to come from your EdgeRouter’s public IP.
• Example commands adjust to your actual interface names:
  • set interfaces openvpn tun0 mode tun
  • set protocols static route 0.0.0.0/0 next-hop
  • set service nat rule 501 source address 10.0.0.0/24
  • set service nat rule 501 outbound-interface tun0
  • set service nat rule 501 type masquerade

Step 4: DNS Configuration and Leak Protection

• Use Surfshark DNS within the VPN tunnel to prevent leaks:
  • Point DNS to Surfshark’s private DNS servers, or rely on VPN-provided DNS.
• Disable DNS caching on the router if possible to ensure fresh lookups.
• Test for leaks:
  • Visit dnsleaktest.com and perform a standard test.
  • Check your public IP via ipchicken or whatismyipaddress to confirm VPN IP is shown.

Step 5: Kill Switch and Security

• Enable a kill switch to block traffic if VPN drops:
  • Create firewall rules that drop all traffic from LAN to WAN unless the VPN interface is up.
• Lock down WAN access:
  • Disable unnecessary remote access SSH, HTTP admin from WAN.
  • Use strong passwords or SSH keys for management.
• Consider a separate guest network:
  • Isolate guest devices from the main VPN-protected network if you want to limit VPN coverage for guests.

Step 6: Performance Tuning for Streaming

• Choose a Surfshark server close to your location to reduce latency.
• Prefer WireGuard for better throughput and lower latency compared to OpenVPN.
• Enable MTU tuning if you experience fragmentation; start with 1480 or the suggested value from Surfshark.
• Turn off bandwidth-intensive unnecessary services on devices while streaming to keep VPN bandwidth available.
• If streaming is choppy, switch to a different VPN server or temporarily disable VPN for a moment to test the connection.

Step 7: Guest Network and Separate VPNs

• You can create a dual-VPN setup for specific devices:
  • Main network uses VPN for privacy
  • Separate guest VLAN uses direct internet access for easier device onboarding
• Use firewall rules to prevent guests from accessing internal resources while still providing internet access.

Step 8: Monitoring and Maintenance

• Regularly check:
  • VPN connection status on EdgeRouter
  • Diskless edge devices’ connections and firewall logs
  • Surfshark account status and server availability
• Schedule periodic reboots or firmware updates to keep performance stable.

Advanced Tips and Tricks

• Split tunneling selective routing
  • Route only sensitive devices through Surfshark to save bandwidth on others like smart TVs or gaming consoles that don’t require privacy.
  • Example: Create a route for 192.168.1.0/24 devices to VPN and 192.168.2.0/24 to direct WAN.
• QoS and bandwidth management
  • Prioritize streaming services Netflix, YouTube over background updates when VPN is in use.
  • Create QoS rules to ensure VPN traffic gets enough bandwidth during peak usage.
• Custom DNS options
  • If Surfshark DNS is slow, you can use a trusted DNS like Cloudflare 1.1.1.1 or Quad9 with DNS-over-HTTPS where supported, but ensure traffic remains within VPN where possible.

Troubleshooting Common Scenarios

• VPN does not connect
  • Double-check server address, keys, and port configuration.
  • Verify that your firewall isn’t blocking VPN traffic.
  • Restart the EdgeRouter and VPN service to reset the tunnel.
• DNS leaks detected
  • Ensure DNS requests are routed through the VPN interface and not using local DNS resolvers.
  • Confirm that the DNS servers are the ones provided by Surfshark within the VPN tunnel.
• Slow speeds on VPN
  • Try a different Surfshark server or protocol.
  • Check for high CPU usage on the EdgeRouter, especially if you’re routing all traffic through VPN.
  • Confirm MTU settings and fragmentation issues; adjust MTU accordingly.
• Streaming buffering or geo-restrictions
  • Check if the VPN server supports the streaming service’s region.
  • Use the streaming service’s region alternative if permitted, or switch to a server with lower latency.

Security Best Practices

• Use a strong admin password and consider MFA if EdgeRouter supports it.
• Regularly update firmware and VPN configuration.
• Keep a separate, isolated guest network to protect your main devices.
• Review firewall rules monthly to avoid inadvertently exposing devices.

Performance Metrics to Track

• Latency ms to VPN server
• Jitter and packet loss during streaming

Why choose Surfshark on EdgeRouter?
– Centralized security: A single VPN run protects every device that connects through your router.
– Cost-effective: No need to purchase VPN licenses per device. one subscription covers all compatible devices.
– Flexible features: Surfshark offers multiple protocols and features like CleanWeb, MultiHop, and robust kill switch behavior when configured on a router.
– Access to global libraries: Bypass geo-restrictions for streaming services on multiple devices at once.

Before you start, a few quick notes
– EdgeRouter devices EdgeRouter X, EdgeRouter 4/6/8, and newer EdgeOS appliances can connect to Surfshark via OpenVPN client configurations, which is the most widely supported route on EdgeOS.
– Surfshark also provides WireGuard configurations, but native WireGuard support on EdgeRouter may require more hands-on setup or community-driven workarounds depending on your firmware. OpenVPN tends to be the simpler, rock-solid choice for most EdgeRouter users.
– DNS leaks: Router-level VPN can still leak DNS if the router’s DNS settings aren’t forced through the VPN. We’ll cover how to prevent that with EdgeOS firewall and DNS settings.
– Kill switch: We’ll show how to implement a basic router-side kill switch so that if the VPN drops, traffic doesn’t leak unencrypted.

Core concepts you’ll apply
– A VPN tunnel between your EdgeRouter and Surfshark servers.
– A VPN interface on EdgeRouter to carry all outbound traffic.
– Firewall rules that ensure VPN-only traffic by default, with optional exceptions.
– DNS settings that resolve through the VPN network to avoid leaks.

Step-by-step setup: OpenVPN on EdgeRouter with Surfshark
Note: This section uses OpenVPN because it’s the most widely supported and straightforward method for EdgeRouter. If you’re comfortable experimenting with WireGuard, you can adapt some steps for WireGuard as needed.

1 Gather Surfshark OpenVPN configuration
– Log in to Surfshark, go to the VPN settings, and download the OpenVPN configuration files usually one for TCP and one for UDP, and often both IPv4 and IPv6 variants. You’ll typically select a server location and protocol UDP is commonly faster.

2 Prepare EdgeRouter for VPN
– Connect to your EdgeRouter’s UI https://192.168.1.1 or whatever you’ve set, and ensure you’re on the latest EdgeOS firmware.
– Create a new VPN interface. In EdgeOS, you’ll typically add an “OpenVPN” client interface, then configure it with the certificate, key, and server address from Surfshark’s OpenVPN config.

3 Enter OpenVPN client details
– Server address: the Surfshark OpenVPN server you chose
– Protocol: UDP recommended for speed
– Port: as specified in Surfshark’s config can be 1194 or another port
– TLS/CA certificates: upload or paste as required by Surfshark’s config
– Authentication: use the credentials Surfshark provides if necessary some configurations rely on embedded auth

4 Create a routing plan
– Add a static route so all traffic from the LAN goes through the VPN interface you just created.
– Ensure your default route points to the VPN interface. In EdgeOS, this is typically done by setting the VPN interface as the primary outbound interface for the LAN subnet.

5 Set up DNS through the VPN
– Point your EdgeRouter’s DNS to Surfshark’s DNS servers or use a public DNS that respects privacy, but ideally go through the VPN tunnel. This reduces DNS leaks and keeps name resolution private.

6 Implement a basic VPN kill switch
– Create firewall rules that block all outbound traffic from the LAN if the VPN interface is down or not connected.
– A simple approach: set a firewall policy on the LAN to deny traffic unless it’s allowed via the VPN interface. Then add a rule to accept traffic if the VPN interface is up, and a “drop” rule by default if not.

7 Test and verify
– Reboot EdgeRouter and confirm the VPN interface comes up.
– Use a device connected to your network to test your public IP search “what is my IP” on a browser and verify it shows the Surfshark server’s IP.
– Test for DNS leaks by visiting a site that shows DNS information e.g., dnsleaktest.com and confirm it lists Surfshark’s DNS servers.

8 Optional: split tunneling device-level routing
– If you want certain devices to bypass the VPN for local network access or to reduce latency, you can create more granular firewall rules or routes that bypass the VPN for those devices.
– A common use case is keeping smart home devices on the local network without forcing VPN traffic through them, while streaming devices use the VPN.

Performance and optimization tips
– Server choice matters: Distance and load are real factors. For Canada, closer Surfshark servers generally give you lower latency. test a few nearby locations to compare speeds.
– Protocol trade-offs: OpenVPN is robust and compatible, but if your EdgeRouter supports WireGuard behind the scenes, you might see better throughput and latency with WireGuard. In most cases, OpenVPN remains reliable on EdgeRouter.
– MTU considerations: If you experience dropouts or slow connections, try adjusting MTU to around 1200-1400 on the VPN interface. Small tweaks can prevent fragmentation and improve stability.
– DNS leaks: Always verify DNS while connected to Surfshark. If leaks appear, adjust DNS settings to force DNS through the VPN use Surfshark’s DNS or a privacy-respecting DNS service that is only reachable via the VPN.
– Kill switch reliability: The router-level kill switch depends on firewall configuration. If you notice leaks when you disable VPN, revisit firewall rules and defaults. It’s better to block traffic by default and only allow VPN-backed traffic.

Advanced EdgeRouter tips
– Multi-hop idea on a router: Surfshark’s MultiHop is relevant for some devices, but on a router, it largely depends on Surfshark’s server availability and EdgeOS routing. If you’re seeking extra hops for privacy, you might configure two VPN interfaces with careful routing or use a dedicated secondary router behind the EdgeRouter, but this adds complexity.
– IPv6 considerations: Some VPN configurations don’t tunnel IPv6 by default. If your network uses IPv6, ensure DNS and IPv6 routing are properly configured so IPv6 traffic also goes through Surfshark or disable IPv6 on the LAN if you don’t need it.
– Logging and privacy: EdgeRouter doesn’t log user activity by default, but it does handle routing. Rely on Surfshark for the privacy layer, and keep EdgeRouter’s firmware up to date to close vulnerabilities.

Performance expectations and realistic numbers
– In Canada, expect VPN speeds to drop by 10-40% depending on server distance, plan congestion, and your baseline Internet speed. Closer servers typically show smaller reductions, and high-capacity connections are less affected by VPN overhead.
– Latency can increase by 5-30 ms on domestic VPN routes. cross-border routes may show more noticeable latency increases, especially if your base connection isn’t fast.
– For streaming, many users report smooth 4K playback when connected to nearby servers, provided the VPN server supports the streaming service you’re using. Some services actively block VPNs, so you may need to switch servers or use features like Surfshark’s NoBorders mode if available.

EdgeRouter vs other options: when to choose router-based VPN
– Pros: One VPN for all devices, no per-device login hassles, consistent firewall control, simpler parental controls and access restrictions.
– Cons: Setup can be technical, some features like app-specific kill switches aren’t as granular as dedicated VPN apps, and router CPU can limit throughput on encrypted traffic.
– If you’re primarily streaming on a few devices or want a simpler management layer, a dedicated VPN app on devices may be easier. If you want network-wide protection and a centralized setup, router-based VPN with EdgeRouter is a solid choice.

Security best practices for Surfshark on EdgeRouter
– Keep EdgeRouter firmware up to date to reduce risk from vulnerabilities.
– Use strong, unique admin credentials for the EdgeRouter interface and enable two-factor authentication if available.
– Periodically rotate Surfshark credentials if you use per-user OpenVPN credentials and refresh OpenVPN configuration files when Surfshark updates servers or certificates.
– Use a reliable firewall policy to limit exposure on the LAN. block unnecessary ports and keep default-deny in place where it makes sense.
– Consider enabling a hardware firewall or intrusion detection features if your EdgeRouter model supports it.

Common issues and quick fixes
– VPN won’t start: Double-check the OpenVPN credentials and certificate configuration, ensure the server address is correct, and verify the VPN interface is added as a route for LAN traffic.
– DNS leaks: Verify DNS settings. force DNS through the VPN and disable non-VPN DNS settings.
– Higher latency: Try different Surfshark servers closer to your location. test both UDP and TCP configurations if available.
– Incomplete client install: Re-upload the OpenVPN config, verify file permissions, and reapply firewall rules after enabling the VPN interface.
– Split tunneling not functioning: Re-check the routing rules. ensure the device-specific exemptions are correctly mapped to the LAN IP addresses or MAC addresses.

Comparisons and use cases
– EdgeRouter + Surfshark for households with many devices: Great for families where you want VPN protection without configuring dozens of devices individually.
– EdgeRouter for advanced users: If you enjoy customizing routing rules, firewall policies, and DNS settings, EdgeRouter gives you ample control.
– Router-based VPN vs. software VPN on devices: A router-based approach reduces the maintenance burden on each device while providing a consistent privacy perimeter.

If you’re considering alternatives
– Other routers with stronger native VPN support like some ASUS or Netgear models may offer simpler UX for first-timers, but EdgeRouter’s flexibility can be a big win for power users who want precise routing rules and custom firewall configurations.
– If you want a faster, plug-and-play experience, a dedicated VPN router with built-in VPN features might save time, but at the cost of flexibility and customization.

What to watch for with streaming services
– Some streaming services actively block VPNs. If you run into a block, switch to a different Surfshark server or use a feature like the router’s kill switch to preserve a streaming session without exposing your real IP.
– If you require access to multiple libraries, test a few nearby Surfshark servers to see which ones unblock your streaming services most reliably.

Maintenance and long-term care
– Periodically audit your firewall rules and VPN interface configurations to ensure they’re still correct after firmware updates.
– Review attached devices monthly to ensure no new devices are circumventing the VPN unintentionally.
– Backup EdgeRouter configurations after a successful VPN setup so you can restore quickly if you ever need to reset.
