Introduction to Ubiquiti EdgeRouter VPN client
EdgeRouter devices run EdgeOS, which is a feature-rich, CLI- and GUI-driven platform designed to handle complex networking tasks in small-to-medium deployments. The built-in VPN client capabilities primarily revolve around IPsec for both remote access and site-to-site connections. While OpenVPN support on EdgeRouter OS has historically been more limited or reliant on workarounds, the core EdgeRouter VPN client story remains: fast, reliable IPsec VPNs with granular control over policies, NAT, firewall rules, and routing. If you’re aiming to connect individual devices to a central VPN gateway or interconnect two offices, EdgeRouter’s IPsec configuration is typically the most straightforward path. For those who want OpenVPN-style flexibility, there are ways to integrate OpenVPN via Docker containers or external servers, but that’s usually outside the “built-in VPN client” workflow and requires more hands-on tinkering.

In practice, the big decision comes down to: do you want a remote-access VPN each client connects to your EdgeRouter or to another gateway or a site-to-site VPN EdgeRouter establishes a persistent tunnel to a counterpart? IPsec handles both well, with strong encryption defaults AES-256, SHA-256, 2048-bit DH groups and broad cross-vendor compatibility. This guide aims to give you actionable steps for both modes, plus practical considerations around hardware capacity, throughput, and secure defaults.

Section overview: what you’ll configure and why

• IPsec remote access client-to-site: You’ll typically configure a server on EdgeRouter that remote clients authenticate to. EdgeRouter can do this directly with an integrated IPsec stack, so each user/device can join the network securely without exposing additional service points.
• IPsec site-to-site: This creates a permanent tunnel between two networks for example, a branch office and HQ. You configure matching settings on both ends: phase 1 and phase 2 proposals, pre-shared key or certificates, tunnel networks, and a proper NAT traversal strategy if needed.
• OpenVPN options: If you absolutely need OpenVPN-style functionality, EdgeRouter can be paired with external OpenVPN services or containers in many setups. It’s not as native or turnkey as IPsec on EdgeRouter, but it’s doable for specialized needs.

Prerequisites and security considerations you should lock in first

• Hardware and firmware: Ensure you’re on a recent EdgeOS version. EdgeRouter X, X-SFP, Infinity, or Pro devices all can handle IPsec VPNs, but performance varies by CPU. If you expect multiple concurrent VPN tunnels or heavy traffic, a higher-end model is worth it.
• Network layout: Know your internal subnets, WAN IP static IP preferred, and the public IP address of the remote VPN peer. Plan the tunnel networks so they don’t overlap with internal LANs.
• Firewall and NAT: VPN traffic must be allowed through the EdgeRouter’s firewall. Specifically, you’ll open IKE UDP 500 and IPsec ESP protocol 50 traffic, plus NAT-T UDP 4500 if you’re behind NAT.
• Authentication and encryption: Use strong IKE phase-1 settings IKEv2 preferred if both sides support it and AES-256 for data encryption with a robust authentication method PSK or certificates. For site-to-site, consider certificate-based authentication for better security than a shared PSK.
• DNS and leaks: Implement DNS leak protection so your VPN clients don’t leak DNS requests outside the tunnel. This is especially important for remote-access VPN scenarios.
• Kill switch and routing: Consider a kill switch approach in the EdgeRouter’s firewall rules so that if the VPN drops, sensitive traffic doesn’t route unencrypted. You can set up policy-based routing to ensure VPN-only paths for certain subnets.

Core VPN setup patterns you’ll likely use

• Remote access IPsec: One EdgeRouter acts as a VPN server. remote clients authenticate with a PSK or certificates. You’ll define address pools for VPN clients, set up IKE policies, and configure a tunnel interface that routes traffic into your internal networks.
• Site-to-site IPsec: Two EdgeRouters or an EdgeRouter and another vendor’s device create a tunnel between two networks. You’ll configure a tunnel on each side with matching IKE and ESP proposals, NAT-traversal settings, and traffic selectors that cover your internal networks.
• OpenVPN workflow optional: If you opt for an OpenVPN-based approach, you’ll likely run an OpenVPN server externally and have EdgeRouter act as a client, or you’ll deploy an OpenVPN container on a local server and route traffic accordingly.

Step-by-step: configuring IPsec remote access on EdgeRouter typical scenario
Note: The exact UI labels can vary by EdgeOS version, but the flow is consistent.

1. Gather essential details

• Public IP or dynamic DNS name of the EdgeRouter for remote clients to connect to
• The VPN authentication method PSK or certificates you’ll use for clients
• The internal LAN networks to be accessible via VPN
• Any preferred DNS settings to push to clients to prevent leaks

2. Create the VPN server IPsec on EdgeRouter

• Log in to the EdgeRouter web UI
• Go to VPN or IPsec section may be labeled as “IPsec VPN” or under “Service” -> “VPN”
• Create a new Phase 1 IKE policy: set IKE version IKEv2 preferred if supported, encryption AES-256, hash SHA-256, group 2048-bit DH, and a secure lifetime
• Create a Phase 2 ESP policy: encryption AES-256, integrity SHA-256, perfect forward secrecy, and a suitable lifetime
• Define the pre-shared key PSK or select certificate-based authentication
• Specify the VPN server’s internal pool for remote clients e.g., 192.168.100.0/24
• Set up DNS server options to push to clients, if desired
• Create firewall rules to allow IPsec traffic UDP 500, UDP 4500, ESP

3. Create a user or user group for remote access if using certificate-based or per-user auth

• Add VPN credentials or certificate profiles for each user
• Ensure user accounts align with your identity provider if you’re integrating with LDAP or RADIUS

4. Define routing and access

• Create a VPN interface or configure static routes so VPN clients can reach your internal networks
• Decide which subnets should be accessible via VPN avoid overlapping with LANs

5. Enable NAT rules for VPN clients if needed

• If VPN clients should be visible on the internet via NAT, configure source NAT for VPN subnets
• Ensure internal devices can respond to VPN clients with proper routing

6. Test the remote connection

• On a client device, use an IPsec-capable VPN client to connect using the server’s public IP, chosen authentication method, and the correct tunnel settings
• Verify reachability to internal devices, test ping, and test access to internal services
• Monitor EdgeRouter logs for any negotiation issues or dropped packets

Step-by-step: configuring site-to-site IPsec VPN EdgeRouter to another gateway

1. Gather partner details

• Remote gateway public IP
• Local and remote subnets to be tunneled
• Authentication method PSK or certificates
• IKE and ESP proposal preferences AES-256, SHA-256, DH group

2. Create a site-to-site tunnel on EdgeRouter

• In IPsec section, choose “Site-to-Site” or equivalent
• Enter the remote gateway’s IP
• Enter the local and remote subnets that will be included in the tunnel
• Define Phase 1 and Phase 2 settings IKEv2 if supported
• Configure pre-shared key or certificate details
• Add a firewall rule to permit tunnel traffic

3. Repeat on the remote gateway

• Use matching IKE/ESP settings
• Ensure both sides have compatible MTU settings to avoid fragmentation
• Confirm the tunnel’s status and monitor logs to ensure the phase negotiations complete successfully

4. Validate reachability

• From each side, test connectivity to devices on the peer network
• Confirm that traffic adheres to the intended route table and that DNS resolution works across the tunnel if required

Performance, security, and best practices you should know

• Encryption overhead: IPsec with AES-256 can add noticeable CPU load, especially on smaller EdgeRouter models. Expect some throughput drop relative to non-VPN traffic. a powerful EdgeRouter Pro or similar device handles multiple concurrent tunnels more smoothly.
• CPU and tunnel counts: The number of concurrent VPN tunnels you support is CPU-bound. If you’re running several remote-access clients or multiple site-to-site tunnels, anticipate higher CPU usage. For busy offices, consider a higher-end EdgeRouter model.
• MTU and fragmentation: VPN encapsulation adds headers. set MTU carefully to avoid fragmentation. A common starting point is to set MTU to 1500 minus VPN overhead and tune from there.
• DNS protection: Push DNS servers to VPN clients to prevent DNS leaks. If you don’t push DNS, clients may query local DNS servers that reveal VPN activity or leak information.
• Kill switch: Implement a policy-based route that forces all traffic for VPN-connected devices through the VPN tunnel. If the tunnel drops, you can block non-VPN traffic to protect data.
• Certificates vs PSK: Certificates generally offer stronger authentication and easier management in larger deployments. PSKs are simpler for small setups but require tighter PSK management.
• Monitoring and logging: Enable verbose VPN logs for troubleshooting. Watch for negotiation failures, mismatched proposals, or certificate issues.
• Redundancy: If uptime is critical, consider a secondary VPN path or an alternate gateway so clients can fallback if the primary tunnel goes down.

Common issues and quick fixes

• Mismatched IKE/ESP proposals: Double-check your Phase 1 and Phase 2 settings on both sides. Even a small mismatch AES-256 vs AES-128, SHA-256 vs SHA-1 will kill the tunnel.
• Incorrect NAT-T behavior: If you’re behind NAT, ensure NAT-T is enabled and that UDP 4500 traffic can reach the VPN peer.
• Overlapping subnets: Ensure VPN tunnel subnets don’t overlap with your LAN or other VPNs. Overlaps cause routing issues and traffic confusion.
• Firewall blocks: If the tunnel is established but traffic isn’t flowing, reexamine firewall rules to ensure VPN traffic is allowed both inbound and outbound.
• DNS leaks: If VPN clients resolve DNS outside the tunnel, ensure the VPN pushes resolver addresses or configure DNS filtering inside the VPN.

Real-world tips and practical considerations

• Start with a simple remote access VPN to a single test device before expanding to multiple clients. This makes it easier to identify misconfigurations.
• Use a static public IP for the EdgeRouter when possible to avoid client reconfiguration each time an IP changes dynamic DNS is an option, but it adds complexity.
• Maintain a documented set of VPN configs. If you have multiple sites or users, a well-documented config baseline saves time during onboarding and troubleshooting.
• Test from multiple device types Windows, macOS, iOS, Android to catch platform-specific quirks.
• Consider logging and alerting so you know when VPN tunnels go down. A simple alerting rule can save hours of debugging.

What if you need OpenVPN or other VPN types?

• Built-in OpenVPN on EdgeRouter: Native OpenVPN server/client support on EdgeRouter OS has historically been limited or more complex. If you require OpenVPN for compatibility with a specific client, you might run an OpenVPN server on a separate device or container and route traffic to/from EdgeRouter, or use a dedicated VPN appliance that supports OpenVPN more natively.
• WireGuard: If you’re exploring newer security options, some EdgeRouter models and firmware have started supporting WireGuard in modern EdgeOS versions. Check your firmware notes to confirm WireGuard availability and performance expectations.
• Hybrid approaches: You can use IPsec for most traffic and supplement with OpenVPN or WireGuard for specific devices or segments if your environment demands that mix.

Performance and benchmarking: what to expect

• Typical CPU overhead: A small EdgeRouter may see a 5–15% to 30% decrease in throughput under load when VPN is active, depending on encryption, tunnel count, and hardware. Higher-end models can handle dozens of VPN tunnels with modest throughput impact.
• Latency impact: VPN tunnels add some latency due to encryption, encapsulation, and routing. For real-time apps Voice over IP, video conferencing, plan for a small increase in latency and jitter and adjust MTU/Routing accordingly.
• Reliability: EdgeRouter VPNs are generally robust, but like any VPN stack, you’ll want to ensure firmware is up to date, security patches are applied, and you’ve got a clear backup plan for configuration changes.
