Note on scope and expectations: EdgeRouter X is a compact, affordable router that runs EdgeOS VyOS-based. It’s powerful for a home or small office, but VPN performance is CPU-bound. Expect VPN throughput to be a fraction of the raw WAN speed, especially with OpenVPN or IPsec running on a 650–1,000 MHz CPU. With careful cipher choice, sane MTU settings, and a clean routing policy, you can get a stable, private connection without turning your network into a slug of buffering.

Body

Prerequisites: what you need before you begin

EdgeRouter X with up-to-date EdgeOS firmware. If you’re not on the latest release, update to ensure you have the latest OpenVPN/IPsec features and bug fixes.
A reliable VPN service or a private VPN server you control. This could be a commercial provider offering OpenVPN or IPsec configuration files, or your own VPN server on a trusted host.
VPN credentials and configuration artifacts:
- For OpenVPN: a VPN profile, OpenVPN CA certificate, client certificate if required, client key if required, and possibly a TLS auth key.
- For IPsec/L2TP: a server address, a pre-shared key or certificate, and user credentials.
A computer or device to test with, plus a basic familiarity with the EdgeOS Web UI or the CLI if you prefer the terminal.
Optional but recommended: a secondary DNS option like 1.1.1.1 or 9.9.9.9 to avoid relying on the VPN provider’s DNS entirely, which helps prevent DNS leaks.

VPN technology options for EdgeRouter X

EdgeRouter X supports multiple VPN approaches. In 2025, the two most practical and widely supported on EdgeOS are OpenVPN client and IPsec/L2TP client. Here’s how they stack up:

OpenVPN Client
- Pros: Broad compatibility with many VPN providers, strong community support, good security features TLS, certs, flexible traffic routing.
- Cons: CPU-intensive, which can limit throughput on a small router like EdgeRouter X. some providers require importing several certificate files.
IPsec/L2TP Client
- Pros: Generally lighter on CPU than OpenVPN. easier to deploy with many corporate-style VPNs. good for mobile devices if you’re connected via a VPN-enabled site-to-site.
- Cons: Setup can be fiddly with pre-shared keys and certificates. less flexible for complex routing scenarios. sometimes perceived as less robust for certain network topologies.
WireGuard where supported
- Note: EdgeRouter X’s stock EdgeOS support for WireGuard varies by firmware version. If your EdgeOS version includes WireGuard support, it can offer excellent performance with a simpler configuration. If not, you may choose to stick with OpenVPN or IPsec for reliability.

In this guide, you’ll see two primary paths explained: a robust OpenVPN client setup and a solid IPsec/L2TP setup. Pick the one that aligns with your VPN provider’s offerings and your performance goals.

Path 1: OpenVPN client setup on EdgeRouter X

OpenVPN is the most versatile option, especially if your provider supplies or prefers .ovpn profiles. Here’s a practical, high-level setup flow you can adapt to your exact environment.

Gather your OpenVPN materials

OpenVPN server address or hostname
Port and protocol UDP is common. TCP is used in some setups
CA certificate and, if required, client certificate and client key
TLS auth key if your provider uses tls-auth or tls-crypt

Access EdgeRouter X UI

Connect your computer to the EdgeRouter X LAN, then open a browser to the router’s management IP often 192.168.1.1.
Log in with admin credentials.

Create the VPN client

In the EdgeOS UI, look for the VPN/OpenVPN section.
Choose “Add/OpenVPN Client” and configure:
- Server address and port
- VPN protocol UDP/TCP
- Client mode tap or tun as appropriate
- Authentication: certificate-based CA, cert, key or username/password if your provider supports it
If your provider requires TLS authentication, import the tls-auth or tls-crypt key.

Import certificates and keys

Paste or upload the CA certificate, client certificate, and client key as required by your provider.
If your provider uses a single inline .ovpn profile, you may need to extract the separate pieces CA cert, client cert, client key and paste them into the corresponding fields.

Configure routing and firewall

Create a VPN interface the UI usually names it something like tun0 or vpn0.
Add a default route via the VPN interface when the VPN is up.
Add firewall rules to allow VPN traffic and to prevent leaks more on this in a dedicated section below.
Consider split tunnel vs full tunnel behavior:
- Full tunnel: All traffic goes through the VPN.
- Split tunnel: Only specific destinations route via VPN. the rest uses your normal WAN.

Apply, test, and verify

Apply the changes and bring the VPN up.
Verify the VPN is connected by checking the interface status and by visiting an IP-check site e.g., what is my IP to confirm the VPN server’s IP is seen.
Run a DNS leak test by visiting a DNS leakage checker and ensure DNS requests resolve via the VPN provider if you’ve configured DNS through the VPN.

Auto-connect and reliability

Enable auto-connect on boot to ensure the VPN comes up after a power cycle.
Some users set up a simple watchdog script that restarts the VPN if it drops, but be mindful of potential loops.

Tips for OpenVPN on EdgeRouter X

Keep MTU in a sane range often 1400-1500 to avoid fragmentation that hurts performance.
If you notice instability, try a different cipher or disable TLS options you don’t need consistent with your provider’s recommendations.
If your provider requires TLS-auth, be precise with the key direction 0/1.

Path 2: IPsec/L2TP client setup on EdgeRouter X

IPsec/L2TP is a more lightweight option that works well with many enterprise-style VPNs and some home setups. Here’s a practical workflow: Firefox not working with vpn try these fixes now

Gather IPsec/L2TP materials

VPN server address
A pre-shared key PSK or certificate-based authentication
Your VPN username and password if required
As with OpenVPN, log in to the EdgeRouter X management interface.

Create the IPsec/L2TP client

In EdgeOS, navigate to the VPN section and select IPsec/L2TP client.
Configure:
- Server address
- Authentication method PSK or certificate
- Local and remote identifiers if required
- User credentials if L2TP uses a username/password scheme
Some setups require you to enable L2TP client on the EdgeRouter and pair it with an IPsec phase 1/phase 2 configuration.

Routing and DNS

Add a route to route default traffic through the VPN when active or use split tunneling if supported.
Consider using VPN-provided DNS or set a trusted DNS to reduce leaks.

Apply, test, and verify

Bring the VPN client up and verify by checking the public IP and performing an IP geolocation check.
Validate DNS resolution to ensure there’s no DNS leakage.

Auto-connect and reliability

Configure the IPsec/L2TP client to start on boot for automatic protection.

PSK-based configurations are simpler but can be vulnerable if the shared key is weak. Prefer certificate-based authentication when possible.
The VPN’s performance is typically better than OpenVPN on idle CPU power, but actual throughput depends on cipher choices and server capabilities.
If the VPN provider supports it, use modern IKEv2/IPsec profiles or a well-supported pre-shared key with strong ciphers AES-256, SHA-256.

DNS, leaks, and security best practices

Leaks are the biggest gotcha when setting up VPNs on home routers. To minimize DNS and IP leaks:
- Route DNS requests through the VPN, or configure the EdgeRouter to use a trusted DNS server that resolves via the VPN tunnel.
- Use a kill switch-like behavior: ensure all non-VPN traffic is blocked if the VPN disconnects.
- Regularly test for leaks with reputable tools DNS leak tests, IP address checks, WebRTC tests in browsers if you’re testing from laptops or desktops.
Keep firmware updated: VPN security is not a one-and-done setup. firmware updates often contain important security fixes and protocol improvements.

Performance and monitoring tips

Expect some performance hit when using OpenVPN due to CPU overhead. IPsec/L2TP generally performs better on this hardware, but real-world results vary with cipher selection and VPN server load.
Use a VPN provider’s recommended cipher suite and TLS options. avoid legacy ciphers unless absolutely required by your provider.
For best stability, allocate a dedicated firewall rule set that only allows VPN-related traffic through the VPN interface to prevent accidental exposure.
Log enough to troubleshoot, but be mindful of privacy. Logging VPN activity on a home router is sometimes helpful for diagnosing issues but can reveal sensitive information if accessed by others.

Practical testing steps you can perform after setup

Check external IP: Visit whatismyipaddress.com to confirm the VPN’s IP is visible and belongs to the VPN provider.
Check DNS: Use DNS leak test tools to ensure your DNS queries do not reveal your ISP’s servers.
Internal routing test: From a device on your LAN, try accessing a resource on a remote network that should only be reachable via VPN. test both when VPN is up and when it’s down.
Disconnect/reconnect tests: Power cycle the EdgeRouter and ensure the VPN reconnects automatically. verify fallback to direct WAN if the VPN fails depending on your policy.

Troubleshooting common problems

VPN won’t connect: Double-check server address/port, credentials, and certificate imports. Ensure the EdgeRouter has the correct time if certificate-based authentication is used.
DNS leaks: Confirm that all DNS traffic is routed via VPN and that the EdgeRouter’s DNS settings are not bypassing the VPN.
Slow speeds: Consider lowering MTU/MSS, switching to a lighter cipher where provider permits, or testing a different VPN server or protocol.
VPN drops after idle time: Enable auto-reconnect, and consider keepalive settings if your provider supports them.
Routing issues: If you’re using a split-tunnel setup, ensure that your routes are correctly configured and not conflicting with existing LAN routes.

Security hardening after setup

Change the admin password for the EdgeRouter UI to something strong, and disable remote management if not needed.
Regularly check for firmware updates and apply them promptly.
Use a strong VPN authentication method. prefer certificate-based OpenVPN or IPsec with robust keys.
Consider additional firewall rules to limit VPN exposure to only necessary services and ports.

Real-world tips and best practices

Start with a simple setup: Get a basic OpenVPN client working first before layering on split tunneling, DNS hardening, and auto-reconnect rules.
Document your configuration: Save a plain-text copy of your VPN settings, routes, and firewall rules in a secure place. This makes recovery quick after a power outage or a firmware upgrade.
Test on a single device first: Before rolling out to multiple devices or a whole home, verify that the VPN works as expected on a single test device.
If you’re benchmarking: Run simple throughput tests during off-peak hours, and compare the OpenVPN vs IPsec options using the same VPN server to understand the real-world trade-offs on your EdgeRouter X.

Case study: typical EdgeRouter X VPN performance

A common scenario is a home network with a 1 Gbps download plan. With OpenVPN on EdgeRouter X, expect practical VPN throughput in the 100–350 Mbps range depending on:

VPN server load and distance
Cipher and TLS settings
MTU/MSS adjustments
Whether you’re routing all traffic or only specific destinations
With IPsec/L2TP, you may see a modest improvement in sustainable throughput, often landing in the 150–450 Mbps window for a well-optimized setup, still pegged by CPU limits. Your mileage will vary, but the key takeaway is: EdgeRouter X can provide reliable VPN client capabilities with sensible settings, not necessarily maximum theoretical speed.

A quick look at the evolving VPN landscape context for 2025
