Why run a VPN on EdgeRouter X?

EdgeRouter X is a compact, affordable router that can handle a VPN setup if you’re patient with the configuration. Why do this on EdgeRouter X instead of a VPN app on a single device?

Centralized protection: All devices on your network go through the VPN by default.
Better control: You can implement a per-subnet or per-device policy, and you can set up a kill switch at the router level.
Privacy and geolocation flexibility: Your entire home network can appear to be in a different country, which helps with streaming or accessing region-locked services.
Learn-by-doing: It’s a great way to understand how VPNs work, from tunneling to routing and DNS security.

That said, EdgeRouter X is not as plug-and-play as consumer-grade VPN routers. You’ll be editing the EdgeOS configuration and testing the setup. If you want a quick, ready-made solution, you can pair EdgeRouter X with a provider that supports OpenVPN and follow the provider’s client config steps to import into EdgeOS.

Prerequisites and what you’ll need

Before you start, gathering a few things makes the process smoother:

EdgeRouter X with the latest EdgeOS firmware
A reliable power supply and a stable primary LAN for testing
Administrative access to the EdgeRouter X web UI usually 192.168.1.1
An OpenVPN configuration file from your VPN provider or your own OpenVPN server config
A basic understanding of Linux-style networking concepts interfaces, routing, NAT
Optional: a dynamic DNS setup if you’re remote but want to connect back to a fixed hostname

If you’re new to OpenVPN, you’ll typically download either a full .ovpn config with embedded certs/keys or separate PEM files CA, client cert, client key along with the TLS key, depending on how your provider delivers it. For IPsec/L2TP options, you’ll need pre-shared keys or certificates from your VPN service and the remote server address.

Security note: always verify the VPN provider’s server you connect to and ensure you’re using the strongest encryption offered AES-256, SHA-2, etc.. Also consider enabling DNS leak protection and setting a reliable DNS resolver inside EdgeOS rather than relying on your ISP’s DNS to prevent leaks.

OpenVPN client on EdgeRouter X: step-by-step GUI method

This method imports a ready-made OpenVPN client configuration and routes all traffic through the VPN by default. It’s the most common approach for home users who want a straightforward setup.

Prepare your OpenVPN config

If you’ve got a single .ovpn file with embedded certificates, you’re ready to go.
If you’ve got separate certs/keys, organize them into a single directory and ensure you have:
- ca.crt
- client.crt
- client.key
- ta.key TLS-auth key if provided
- .ovpn file with the server address and port

Access the EdgeRouter X UI

Open a browser and navigate to http://192.168.1.1 or the IP you’ve assigned.
Log in with admin credentials.

Import OpenVPN config

Go to the VPN section the exact label can vary by firmware version, often “VPN” -> “OpenVPN”.
If you’re using a single .ovpn file, choose Import and upload the .ovpn file. If you’re using separate certs/keys, you’ll enter the details in the corresponding fields CA certificate, Client certificate, Client key, TLS auth key.
For embedded credentials, some EdgeOS builds allow a simple “Import .ovpn” flow. others require you to paste the content of the .ovpn config and the certificate/key blocks separately.

Create the VPN interface

The UI will typically create a new interface like tun0 or similar named interface e.g., vtun0. Confirm its presence in the Interfaces list.
Ensure the OpenVPN client is set to “Enabled” and that the VPN interface becomes available.

Route all traffic through VPN default route

In the EdgeOS UI, navigate to the firewall or routing section.
Add a policy or choose an option to push 0.0.0.0/0 through the VPN interface, i.e., make VPN the default route.
Save and Apply.

DNS and leaks

Configure the EdgeOS DNS to use a trusted DNS provider while the VPN is active e.g., a privacy-respecting DNS like Cloudflare 1.1.1.1 or a VPN provider’s DNS.
Disable IPv6 on the VPN interface if your VPN doesn’t support IPv6 to prevent leaks, or set IPv6 to route through VPN if supported and properly configured.

Test your VPN

Check the external IP address from a device on your LAN using a browser or a quick curl command e.g., curl ifconfig.me. Confirm it shows the VPN’s IP or the region you selected.
Verify DNS resolution doesn’t leak by visiting a site like whoer.net or dnsleaktest.com.
If leaks occur, revisit the DNS settings and ensure 0.0.0.0/0 traffic is directed through the VPN and that DNS requests route through the VPN tunnel.

Troubleshooting tips

If the VPN interface doesn’t come up, re-upload the config, verify that the CA/certs are correct, and confirm the server address/port in the config matches the VPN provider’s server.
Check the EdgeRouter system logs for OpenVPN messages to identify authentication or certificate issues.
Ensure firewall rules haven’t blocked VPN-related traffic e.g., allow UDP 1194 if your provider uses that port, unless you’re using a different port in the config.

OpenVPN server on EdgeRouter X: allow remote access

Running an OpenVPN server on EdgeRouter X is a great option if you want to connect back to your home network securely from remote locations. It can be more complex, but it gives you full control over who can connect.

Plan your network ranges

Decide on what internal IP range you’ll assign to VPN clients for example, 10.8.0.0/24 or 10.9.0.0/24.
Ensure this range doesn’t conflict with your LAN’s IP range.

Set up the OpenVPN server

In the EdgeOS UI, go to VPN -> OpenVPN -> Server the exact navigation may vary by firmware.
Enable the server and configure:
- Server mode: client-to-site or site-to-site as needed
- Protocol and port UDP 1194 is common, but you can choose another
- Server tunnel network the VPN subnet, e.g., 10.8.0.0/24
- TLS authentication and certificate chain if required you may need to generate server and client certs
- Client certificate authentication if using TLS-based config
Generate or import server certificates and keys. You’ll also create and distribute client certificates to each remote user.

Configure client profiles

Create client profiles for each remote user. For each client, export the .ovpn profile or the separate certs/keys to give the user.
Distribute the client profiles securely to users who will connect.

Firewall and NAT rules

Allow VPN traffic in the firewall to reach the VPN interface and allow established connections back to clients.
If you want remote clients to access devices on your LAN, set up appropriate routing or NAT rules so VPN clients can reach internal hosts.

DNS for VPN clients

Point VPN clients to a DNS server either a public DNS or a DNS resolver you host on your network.
Ensure DNS requests from VPN clients don’t leak to your ISP’s DNS by routing 0.0.0.0/0 through the VPN when connected.

Testing remote connections

From a remote device, import the client profile and connect.
Verify you can ping devices on your LAN and access internal services by hostname or IP.
Check the external IP to confirm the VPN is routing traffic appropriately.

Security considerations

Enforce client certificate validation, revoke ability for lost/stolen devices, and implement a strong password or passphrase for the VPN client when applicable.
Regularly update OpenVPN server components and rotate TLS keys as necessary.

IPsec/L2TP and other options: when to consider them

IPsec/L2TP is another common option for VPNs, especially when you want compatibility with devices that don’t support OpenVPN. On EdgeRouter X, IPsec/L2TP can be configured, but it can be more challenging to set up correctly and securely compared to OpenVPN. If your devices or clients require IPsec, you can use strongSwan or the EdgeOS built-in IPsec configurations where supported. Here are quick notes:

IPsec is often better for compatibility with certain mobile devices and older operating systems, but it may be trickier to configure with NAT and double-NAT scenarios.
Ensure you have a solid key exchange method IKEv2 with certificates is recommended and a robust authentication mechanism.
Consider a fallback plan: if OpenVPN works smoothly, you may prefer OpenVPN as your primary path and reserve IPsec for specific clients that require it.

DNS, IPv6, and routing: avoid leaks and ensure reliability

DNS leaks: configure your VPN to push a DNS server for VPN clients, and set the router to route DNS requests through the VPN when active.
IPv6: many VPNs don’t support IPv6 in all configurations, so you’ll want to decide whether to disable IPv6 on the VPN interface or enable IPv6 routing through the VPN if supported.
Split tunneling: decide if you want all traffic to go through the VPN full-tunnel or only selected traffic split-tunnel. Full-tunnel is simpler and more private. split-tunnel can improve performance for local network access.

Kill switch, firewall rules, and maintenance

Kill switch: set firewall rules so that if the VPN goes down, traffic from sensitive devices is blocked from going out via the WAN interface. This helps prevent accidental data leaks.
Firewall zones: create dedicated zones for VPN interfaces and your LAN, then define precise rules that restrict what can be reached when the VPN is active.
Regular updates: keep EdgeOS up to date, monitor OpenVPN or IPsec software versions, and rotate credentials as needed.
Backups: export and securely store your EdgeRouter X configuration files and VPN certificates/keys. Maintain a versioned backup before making major changes.

Performance considerations and common bottlenecks

Hardware limits: EdgeRouter X is capable, but heavy encryption and long-distance VPN servers can tax CPU cycles. If you experience latency, test with a nearby VPN server and enable hardware offloads if supported.
Server location: choose VPN servers closer to your actual location for better throughput and lower latency.
MTU settings: adjust MTU if you notice packet fragmentation or connection instability. A typical VPN MTU is around 1500 minus overhead. you may need to tweak it for your setup.

Common troubleshooting steps

VPN interface not appearing: re-import the config, verify that the certificate chain is complete, ensure that the server address and port are correct.
Connection drops: check server load, verify no firewall rules are blocking VPN traffic, and monitor for IP or DNS leaks.
Slow speeds: test on a nearby server, check your internet line, and consider enabling performance-oriented VPN servers or upgrading to higher-speed VPN plans.
Certificate issues: verify that the correct certificates are used and haven’t expired. ensure the certificate format is accepted by EdgeOS.

Maintenance and best practices

Document your configuration steps: keep a running note of exact server addresses, ports, and certs you’re using.
Schedule periodic reviews: every few months, test the VPN connection and renew any expiring credentials or keys.
Use a dedicated VPN user for the EdgeRouter, separate from your personal accounts, to minimize risk if credentials are compromised.
Consider a test environment: before applying changes to your main home network, test on a spare edge device or a virtual setup to catch misconfigurations.

Quick comparison: OpenVPN client vs OpenVPN server vs IPsec on EdgeRouter X

OpenVPN client
- Pros: Simple to import, strong community support, robust security.
- Cons: May require more manual tuning for DNS and routing.
OpenVPN server
- Pros: Access to your LAN from remote sites, fine-grained control, good for remote employees.
- Cons: Complex to configure securely, requires certificate management.
IPsec/L2TP
- Pros: Broad device compatibility, native support on many devices.
- Cons: Can be trickier to configure securely, may require more firewall rules.

Choosing the right approach depends on your use case: if you want all traffic to go through a VPN for privacy and streaming, an OpenVPN client setup is a good starting point. If you need remote access to your home network, an OpenVPN server is worth the extra effort. If a specific device requires IPsec, set that up with careful attention to the security details.

Final thoughts and tips

Start small: configure OpenVPN client on EdgeRouter X first and test with a couple of devices before expanding to a full-site VPN or multiple clients.
Document your parameters: server address, port, protocol, and any TLS keys. This reduces cognitive load if you need to reconfigure later.
Security first: always enable DNS protection and consider a router-level kill switch to prevent leaks in case of VPN instability.
If you’re considering a quick, supported option for multiple devices, NordVPN’s current deals as shown above can be a convenient backup while you perfect your EdgeRouter setup.
