EdgeRouter X is a cost-effective, fanless 5-port router that runs EdgeOS. It’s a good fit for people who want more control than consumer “black-box” routers offer, without paying enterprise prices. The trade-off is that VPN setup requires comfort with a command-line-like interface and careful firewall planning.
VPN options you can run on the EdgeRouter X
- OpenVPN server for remote access
- OpenVPN client to connect to a VPN provider e.g., NordVPN and route traffic through the provider
- IPsec site-to-site VPN for connecting to another router or VPN gateway
- L2TP/IPsec if supported by EdgeOS version and hardware for remote devices
- Pretty much any combination, as long as you segment the networks and manage firewall rules properly
In practice, most users pick one of these paths:
- Remote access via OpenVPN server on the EdgeRouter X
- Site-to-site IPsec between two EdgeRouter X devices or between EdgeRouter X and another vendor’s VPN gateway
- VPN client mode on EdgeRouter X to route all traffic through a chosen VPN provider
Setting up OpenVPN server on the EdgeRouter X remote access
Note: OpenVPN server support on EdgeRouter X is a feature of EdgeOS. It requires a recent EdgeOS version and correct certificate management. If OpenVPN server isn’t available in your version, consider upgrading EdgeOS or using an alternative like L2TP/IPsec or IPsec-based remote access.
What you’ll need
- A current EdgeRouter X with EdgeOS
- A static WAN IP or dynamic DNS so remote clients can reach your router
- A CA certificate, server certificate, and client certificates or a simple certificate authority if you’re comfortable with PKI
- A tunnel network for example 10.8.0.0/24

- Step 4: Configure clients
- Import the generated client certificate and.ovpn profile on client devices laptops, phones, tablets
- Ensure routes push correctly to the VPN and that DNS resolves via the VPN if desired
- Step 5: Test
- Connect a client and verify an IP from the remote end, test DNS leaks, and ping internal resources
- Step 6: Maintenance
- Revoke compromised clients, rotate certificates, monitor VPN logs for anomalies
Tips
- Use a strong TLS/cryptography setup e.g., TLS 1.2+, AES-256.
- Consider splitting the VPN network from your LAN to limit blast radius if a device is compromised.
- If you experience unstable connections, try using a different UDP port or switch to TCP in your client config for reliability.
Setting up IPsec site-to-site VPN on EdgeRouter X
IPsec is a robust choice for connecting two sites. It’s widely supported and works well in mixed-vendor environments. This section focuses on a typical site-to-site scenario where you have two EdgeRouter X devices or one EdgeRouter X and a partner gateway.
-
Public IPs or dynamic DNS for both sites
-
A pre-shared key or certificates for authentication
-
Local and remote subnets defined e.g., local: 192.168.1.0/24, remote: 10.0.0.0/24 Windscribe extension chrome
-
Step 1: Configure the IPsec interfaces
- Define the IPsec tunnel endpoint on each side using the peer’s public IP
- Specify the authentication method pre-shared key or certificates
-
Step 2: Set IKE phase parameters
- Choose IKE version typically IKEv2 for better stability and speed
- Configure encryption and integrity e.g., AES-256, SHA-256
- Enable perfect forward secrecy PFS with a suitable DH group
-
Step 3: Create the tunnel and proposers
- Define the local and remote subnets each side will route through IPsec
- Add the tunnel to the IPsec policy so traffic between subnets is encapsulated
-
Step 4: Firewall and NAT considerations
- Ensure traffic between the two sites isn’t NAT’d in a way that breaks IPsec
- Create firewall rules to allow IPsec and related ESP/ah traffic
-
Step 5: Test and monitor Tuxler vpn price: Comprehensive guide to Tuxler pricing, plans, features, and value for money for VPN users in 2025
- Bring up the tunnels and verify connectivity by pinging remote hosts
- Check IPsec status and SA Security Association tables for any drops
-
Step 6: Optimize
- If performance is an issue, adjust MTU/MSS to reduce fragmentation
- Confirm dead-peer detection and keepalive settings are appropriate for your network
Common caveats
- NAT traversal can be tricky. ensure the NAT-T option is enabled if you’re behind NAT.
- IPsec can be sensitive to clock drift. make sure both sites have accurate time NTP.
- Regularly update both devices to keep security current and avoid known bugs.
Using OpenVPN client on EdgeRouter X to connect to a VPN provider e.g., NordVPN
If you want all traffic on your local network to route through a VPN provider, you can configure an OpenVPN client on the EdgeRouter X. This lets you select a VPN server and push its route through your LAN.

-
The ability to install/enable the OpenVPN client on EdgeOS
-
Step 1: Get the OpenVPN config from the provider
- Download the .ovpn file and any needed certificate/key bundles
-
Step 2: Prepare EdgeRouter X
- Create a dedicated routing table or use an interface to isolate VPN traffic
- Add firewall rules to enforce VPN usage if desired
-
Step 3: Configure the OpenVPN client
- Import the .ovpn config and point EdgeOS to use the VPN tunnel as the default route
- Ensure DNS requests are routed through the VPN if you want DNS privacy
-
Step 4: Test and verify Cutting edge veterinary VPNs for secure remote access and data protection in clinics and telemedicine
- Check the public IP seen by external services to confirm VPN usage
- Verify that internal LAN devices can reach the Internet through the VPN tunnel
-
Step 5: Reliability and fallback
- Consider a policy to revert to the local WAN if the VPN goes down to avoid total outage
- Monitor VPN uptime and implement reconnect logic if supported
Notes and caveats
- Not all VPN providers support every EdgeRouter X model identically. some providers require manual config tweaks.
- OpenVPN on EdgeOS can be sensitive to CPU load. the ER-X hardware is modest, so heavy usage per device may impact speeds.
- If you’re using NordVPN specifically, they provide OpenVPN configurations that you can adapt for EdgeRouter X. expect to adjust DNS and routing to prevent leaks.
Performance considerations when using VPN on the EdgeRouter X
- CPU constraints: The EdgeRouter X isn’t the fastest router in the fleet, so heavy VPN encryption tasks can reduce throughput. Expect VPN-tunneled speeds to be lower than the raw WAN-to-LAN throughput of the device.
- Network topology: If you have multiple clients behind the ER-X, ensure you balance VPN usage with local network needs. Consider VLANs to separate VPN clients from household devices.
- DNS handling: Decide if you want DNS queries to go through the VPN tunnel or remain local. For privacy, routing DNS through the VPN is common, but it adds a little latency.
- MTU and fragmentation: VPNs add overhead. If you see slow connections or packet loss, experiment with MTU/MSS settings on the OpenVPN client or server to reduce fragmentation.
- Redundancy: For critical sites, pair IPsec with a backup path or keep a static route for essential services so you’re not entirely dependent on a single VPN path.
Security best practices for VPNs on EdgeRouter X
- Use strong authentication: choose TLS or certificates instead of simple pre-shared keys where possible.
- Regularly rotate keys/certificates and revoke access for users who no longer need it.
- Segment VPN traffic: keep VPN users separated from your admin networks and sensitive resources.
- Keep EdgeOS updated: security fixes land in newer EdgeOS releases. ensure you’re running supported firmware.
- Firewall discipline: only allow VPN traffic to needed services, and log VPN connections for monitoring.
Troubleshooting quick tips
- If clients can connect but can’t reach internal resources, check routing tables and firewall rules on the EdgeRouter X.
- If VPN tunnels keep flapping, verify your network’s WAN stability, check MTU sizes, and review log messages for encryption disagreements.
- For OpenVPN: ensure you’ve pushed the correct DNS server configuration to clients. a DNS leak can undermine privacy goals.
- If you’re using IPsec and the tunnel won’t come up, verify the IKE version, encryption suite, pre-shared key, and that the remote peer’s IP matches what you expect.
Practical wireframes: real-world scenarios
- Home office with a single remote worker
- Use OpenVPN remote-access on the ER-X, allow the remote worker to connect, and route their traffic through the home network to access files or printers securely.
- Small branch with two network segments
- Use IPsec site-to-site to connect the branch to the main office router, route specific subnets across the tunnel e.g., 192.168.10.0/24 to 10.1.0.0/24, and maintain separate VLANs for guest networks.
- Privacy-focused home network
- Configure the EdgeRouter X as an OpenVPN client for a VPN provider to ensure all traffic from the LAN is hidden behind the VPN, with DNS resolved through the provider’s DNS servers.
