Why use a VPN on a Ubiquiti EdgeRouter?

• Local privacy and remote access: VPN lets you securely reach your home/office network from public Wi‑Fi or when you’re traveling.
• Control and lockdown: You control who can connect, what resources they can access, and how traffic is routed.
• Performance on modest hardware: EdgeRouter devices pack enough CPU and RAM to handle a few OpenVPN or IPsec tunnels without a big hit to internet speed—especially if you optimize the tunnel for UDP and use efficient ciphers.
• Cost-effective remote access: You get enterprise-like VPN capabilities without paying for an enterprise firewall, making it ideal for home labs and small offices.

What EdgeRouter models support VPN?

• EdgeRouter X, EdgeRouter X SFP, EdgeRouter 4, EdgeRouter 6P, EdgeRouter 12, and higher-end EdgeRouter models all support VPN features through EdgeOS.
• The exact UI layout can vary slightly by model and firmware, but the core concepts OpenVPN, IPsec, and WireGuard where available remain consistent.
• WireGuard support: Some EdgeOS firmware versions include WireGuard, but it’s not universally available on all devices or firmware channels yet. If WireGuard isn’t available on your model, you can still rely on OpenVPN or IPsec.

Which VPN protocols should you choose?

• OpenVPN: Widely compatible, easy to export client configs, and works well with typical home internet speeds. Great for Windows/macOS/Linux clients.
• IPsec IKEv2/strongSwan: Fast, stable on mobile devices, and good for site-to-site or road-warrior setups. May require more careful firewall handling.
• WireGuard: Lightweight and fast with modern cryptography. If supported on your EdgeRouter version, it can be an excellent choice for speed and simplicity.
• For most home users starting out, OpenVPN is the most straightforward option. IPsec is excellent for mobile devices. WireGuard is fantastic if you have it at your disposal.

OpenVPN server setup on EdgeRouter step-by-step
Note: The exact UI labels may differ slightly by firmware, but the flow stays similar.

1. Prep and firmware

• Update EdgeRouter to the latest stable firmware via the UI System > Upgrade or via CLI if you prefer.
• Reboot if prompted to ensure services start cleanly.

2. Enable OpenVPN server

• In EdgeOS, navigate to the VPN section Services > VPN > OpenVPN > Server.
• Choose the server type Road Warrior for client connections is the common choice. Site-to-Site is another option if you’re connecting to a remote network.
• Select UDP as the transport, and set a reasonable port 1194 is common, but you can choose another if you have conflicts.
• Define the virtual network for example, 10.8.0.0/24 and DNS settings e.g., 10.0.01 or your local DNS server.
• Pick a cipher AES-256-GCM is a solid default for modern devices, and enable TLS authentication if your UI offers it TLS-auth or tls-auth, using an HMAC key.
• Create a certificate and key for the server if your EdgeRouter UI asks. otherwise, generate using the UI tools provided or import a prepared certificate.
• Export client profile/config after saving the server. This export creates a .ovpn file you can distribute to clients.

3. Create client profiles

• In the same VPN OpenVPN section, add a user or client profile with a username and a password, or generate a client certificate if you’re using certificate-based auth.
• Export the client .ovpn file and test on a computer with OpenVPN software installed. If you’re using certificates, ensure the client has the CA, server cert, and the client cert and key.

4. Firewall and NAT

• Create a firewall rule to allow inbound UDP on the chosen OpenVPN port e.g., UDP 1194 on the WAN interface.
• Ensure OpenVPN traffic is allowed to reach the OpenVPN server interface vtun or tun0, depending on EdgeOS naming.
• Add a masquerade rule NAT for traffic from the VPN network going to the Internet if you want VPN clients to access the broader internet through the EdgeRouter.

5. Routing and DNS

• Decide whether VPN clients should access the whole LAN or only specific subnets. If you want full LAN access, configure push routes accordingly.
• Configure DNS for VPN clients. You can point clients to your local DNS if you have internal resources or to a public DNS like 1.1.1.1, depending on your privacy needs.

6. Testing

• Connect a client using the .ovpn file and verify an IP address from the VPN subnet e.g., 10.8.0.x.
• Check that you can reach internal devices e.g., file share, printer or a test server on the LAN.
• Verify that public IP shown by a test site corresponds to the VPN exit node if you’re using OpenVPN to route all traffic.

OpenVPN tips and caveats

• Push DNS carefully: misconfigured DNS can cause leaks or name resolution problems. Use a reliable DNS and test for leaks with tools like dnsleaktest.com.
• Use TLS-auth if possible: it adds a layer of protection against certain types of attacks and reduces handshake overhead for security-conscious setups.
• Keep client configs organized: use a single .ovpn per client or clearly named files if you’re distributing to multiple devices.

IPsec VPN on EdgeRouter road-warrior and site-to-site
IPsec is a strong choice for mobile clients or for connecting multiple sites. The approach is different from OpenVPN and can yield excellent performance, especially on devices with good crypto acceleration.

1. Decide the topology

• Road warrior remote access: individual clients connect to the EdgeRouter’s IP.
• Site-to-site: connect EdgeRouter at your home/office to a remote EdgeRouter or another IPsec endpoint.

2. Create IKE phase 1 and IPsec phase 2 proposals

• Define the IKE version IKEv2 is common for modern devices, sometimes IKEv1 is still used.
• Select encryption and integrity e.g., AES-256, SHA-256 and a DH group.
• Create a Phase 2 transform set and a corresponding traffic selector subnet-to-subnet for site-to-site.

3. Authentication

• Use pre-shared keys PSK for simplicity in many home setups, or certificates for stronger security in larger deployments.

• Set a strong PSK if you go that route, and ensure it’s not reused across sites.

• Add firewall rules to permit IPsec negotiation UDP/500 and UDP/4500 for NAT-T.

• Allow IPsec traffic on the WAN interface and ensure VPN clients or sites can route through the tunnel.

• For site-to-site, ensure the tunnel networks are not overlapping with your LAN subnets or other VPNs.

5. Client configuration road warrior

• Generate or configure the client to use IKEv2 or the chosen protocol, depending on your EdgeRouter and client capabilities.

• Import the client profile or manually configure the client server address, pre-shared key or certificates, and the VPN subnet.

• Use a device outside your LAN to connect to the VPN and verify reachability to the remote LAN.

• Check for proper DNS resolution and confirm that traffic routes through the VPN as expected.

WireGuard on EdgeRouter where supported
If your EdgeRouter firmware includes WireGuard support, it’s a fast, lightweight option.

1. Enable WireGuard

• In EdgeOS, go to the VPN or Interfaces section to enable a WireGuard interface wg0 and assign it an IP address in a VPN subnet for example, 10.200.0.1/24.

2. Add peers

• Add peer configurations with their public keys and allowed IPs for the remote sides.
• Define a keepalive interval if needed to maintain stability over NAT.

3. Firewall rules

• Create firewall rules to allow WireGuard traffic on the correct port usually UDP 51820 by default and to permit traffic from wg0 to your LAN or VPN subnets.

4. Routing and DNS

• Route VPN traffic to the LAN or Internet as needed.
• Decide whether VPN clients will use your local DNS or a public one.

5. Client provisioning

• Export or provide client config details for devices that support WireGuard Windows, macOS, iOS, Android. Test connections thoroughly.

Security best practices and performance tips

• Keep firmware updated: VPN bugs and security patches are common in firmware releases. Regular updates keep you safer and faster.
• Use strong crypto and modern ciphers: AES-256, SHA-256, and modern handshake methods are standard for robust VPN configurations.
• Limit VPN access: only allow necessary users and devices. use per-user credentials or certificates when possible.
• Split tunneling vs. full tunneling: Decide whether VPN clients should access only the LAN or all internet traffic through the VPN. Full tunneling can impact speeds on slower connections but improves security on untrusted networks.
• DNS leakage checks: After setting up, verify that DNS queries don’t leak outside the VPN tunnel.
• Regular backups: Save your EdgeRouter configuration before making major VPN changes. keep a separate backup in case you need to roll back.
• Logging and monitoring: Enable basic VPN logging to catch misconfigurations or unauthorized access attempts.

Common issues and quick fixes

• OpenVPN won’t connect: Double-check server port and tunnel network. ensure the client config matches the server settings. verify firewall rules allow inbound VPN traffic.
• IPsec handshake failures: Check PSK or certificates, ensure clocks between devices are synchronized, and confirm that the right IKE/ESP proposals are configured on both ends.
• DNS leaks: Confirm that VPN clients are using the VPN’s DNS or a trusted resolver. test with dnsleaktest.com.
• Slow VPN performance: Try using UDP not TCP and AES-256-GCM. ensure you’re not routing excessive traffic or running other CPU-intensive services on the EdgeRouter during VPN use.

Performance considerations for home networks

• CPU and RAM: EdgeRouter devices with higher CPU cores and more RAM handle multiple VPN tunnels better, especially if OpenVPN or IPsec is used with strong ciphers.
• Tunnel count: A single EdgeRouter can handle several OpenVPN connections and a few IPsec tunnels, but performance will degrade as you add more clients and more encryption.
• Network topology: If you have multiple devices streaming concurrently or doing heavy uploads/downloads, plan for QoS and traffic shaping to preserve VPN performance.
• Internet speed: If your WAN connection is slow, VPNs will cap overall throughput. Plan accordingly and consider upgrading your internet plan if VPN performance is critical.

Useful testing tools and metrics

• Ping/Traceroute from VPN clients to LAN devices to check reachability.
• iperf3 tests between VPN clients and a test server to measure real throughput.
• Public IP checks on VPN-connected devices to verify that traffic is tunneled as expected.
• DNS leak tests to confirm DNS queries are resolved within the VPN.

Maintenance and backup

• Regularly export and save VPN configuration snapshots.
• Create a separate backup of the EdgeRouter configuration in case you need to restore quickly after a change.
• Document your VPN setup details server addresses, shared secrets or certificates, and client configuration so you can reproduce or tweak the setup later.
