Body

Why choose OpenVPN on EdgeRouter X

Compatibility and control: OpenVPN runs on virtually any device and OS, and EdgeRouter X gives you full control over routing, NAT, and firewall policies.
Security and auditability: OpenVPN supports strong ciphers AES-256, ChaCha20-Poly1305, TLS authentication, and flexible authentication methods.
Small footprint, big impact: EdgeRouter X isn’t a powerhouse, but with proper tuning it can handle common home or small office VPN needs, especially for remote access and site-to-site setups.

Hardware, firmware, and compatibility notes

EdgeRouter X specs in brief: a compact router designed for basic to moderate loads, with multiple Gigabit ports and EdgeOS firewall features. It’s ideal for a VPN server when you don’t need enterprise-grade throughput.
Firmware and EdgeOS: Make sure you’re on a recent EdgeOS version to ensure OpenVPN server support and up-to-date security patches.
VPN throughput: Expect OpenVPN to deliver hundreds of Mbps on modern routers. on EdgeRouter X, realistic real-world throughput often ranges from 20–100 Mbps depending on cipher choice, TLS overhead, and client hardware. If you need higher bandwidth, consider encrypted tunnels on devices with more CPU power or moving to a site-to-site setup with a more capable router.

Prerequisites and planning your OpenVPN deployment

Decide on your VPN topology: remote access client-to-LAN or site-to-site two EdgeRouter devices. This guide focuses on remote access, where you connect a client device to your home network.
Choose between a full-tunnel all traffic goes through VPN or split-tunnel only selected traffic goes through VPN. Full-tunnel is simpler for privacy. split-tunnel can improve local network performance.
Plan IP addressing: reserve a VPN subnet e.g., 10.8.0.0/24 that doesn’t clash with your LAN subnet.

Step-by-step setup: OpenVPN server on EdgeRouter X
Step 1: Prepare EdgeOS

Log in to EdgeOS via SSH or the web UI.
Back up your current configuration before starting.
Update to the latest EdgeOS if possible to ensure OpenVPN compatibility.

Step 2: Create a VPN subnet and firewall rules

Choose a VPN network for example 10.8.0.0/24.
Create a firewall policy to allow VPN traffic port 1194 UDP by default and to permit traffic from the VPN subnet to the LAN.
Ensure NAT is configured so VPN clients can access the internet through your public IP if you want full tunneling.

Step 3: Build the PKI CA, server cert, client cert

You can generate a simple CA and server/client certs on a PC or use the EdgeRouter for PKI tasks. For simplicity, many users generate the CA and certs on a local PC with easy-rsa and transfer them to the EdgeRouter.
Store server certificate and key on the EdgeRouter, and place client certificate/key files on client devices.

Step 4: Configure the OpenVPN server in EdgeOS Edge add site to ie mode

Create an OpenVPN server instance using the EdgeOS CLI or UI. A typical server config includes:
- mode server
- tls-server
- server 10.8.0.0 255.255.255.0
- push “redirect-gateway def1”
- push “dhcp-option DNS 1.1.1.1” or your preferred DNS
- push “dhcp-option DNS 9.9.9.9”
- cipher AES-256-CBC or AES-256-GCM if supported
- auth SHA256
- tls-auth ta.key 0
- user nobody
- group nogroup
- server-hostname or local IP binding specifics
Enable TLS auth and specify the ta.key static key if using a static-key setup, or configure TLS with the server cert.

Step 5: Create client configuration and certificates

Build a client configuration file .ovpn for each device. Include:
- client
- dev tun
- proto udp
- remote your_public_ip 1194
- resolv-retry infinite
- nobind
- persist-key
- persist-tun
- ca ca.crt
- cert client.crt
- key client.key
- tls-auth ta.key 1
- cipher AES-256-CBC
- comp-lzo
- verb 3
For Windows/macOS/Linux clients, you can embed certificate and key data directly into the .ovpn, or distribute the separate cert/key files.

Step 6: Firewall rules and NAT

Allow traffic from the VPN subnet to the LAN.
Ensure the firewall zone for the VPN interface is trusted for LAN access, or carefully control it with rules to limit exposure.
Add NAT rule to masquerade VPN traffic when you want clients to access the internet through your public IP.

Step 7: DNS and DNS leak protection

Use a private DNS resolver or a reputable public DNS provider.
Consider enabling DNS leaks protection by forcing VPN clients to use your VPN-provided DNS server.

Step 8: Routing and VPN behavior full vs split tunnel

If you want all traffic to go via VPN, keep the redirect-gateway directive.
If you want only traffic to your LAN to go via VPN, adjust push directives or client routes so only specific networks are tunneled.

Step 9: Auto-start and testing Edge vpn ios guide for iOS: how to choose, set up, and use a VPN with Edge on iPhone and iPad

Configure OpenVPN to start on router boot.
From a client device, import the .ovpn profile and test:
- Verify you can reach LAN devices by IP or hostname.
- Check external IP to confirm traffic is coming from the VPN.
- Confirm DNS requests resolve through the VPN DNS to avoid leaks.

Step 10: Backup and recovery

Save a backup of EdgeOS configuration after you confirm VPN functionality.
Keep copies of your CA, server cert, and client certs in a secure location.

Security best practices and optimization

Use strong encryption: AES-256-CBC or AES-256-GCM where supported.
TLS authentication tls-auth or tls-crypt to defend against TLS renegotiation and replay attacks.
Use a strong TLS certificate and rotate certificates periodically.
Separate VPN management network from your IoT devices to minimize lateral movement risk.
Regularly update EdgeOS firmware and monitor for OpenVPN-specific advisories.
Monitor VPN logs for unusual access attempts and limit client IPs if possible.

Practical tips and common configurations you’ll see

Split tunneling is common for home users who want VPN access to the home network plus internet access from the device’s own ISP, not through VPN.
Full tunneling is preferred for privacy-conscious users or when you want all traffic to traverse your home network for logging or content filtering.
If you have dynamic IP from your ISP, set up a dynamic DNS DDNS service to reach your EdgeRouter X easily.
If you’re hosting on a consumer connection, expect occasional instability and tailor keepalive/ping settings to maintain stable tunnels.

Troubleshooting common issues

VPN not starting: double-check the certificate paths, ensure ca.crt, server cert, and key are correctly placed on the EdgeRouter, and review the OpenVPN log for TLS errors.
Clients can connect but can’t reach LAN hosts: verify firewall rules and LAN access permissions for the VPN subnet. ensure proper NAT rules for VPN traffic.
DNS leaks: confirm the VPN pushes DNS settings to clients and that clients are not using the ISP’s DNS resolver.
Slow speeds: try using AES-128-GCM if supported or AES-256-CBC with a smaller TLS key exchange to reduce CPU load. consider enabling compression only if devices support it without explosion of CPU overhead.

Advanced tweaks for power users

Use a separate VPN server instance on EdgeRouter X for remote access and a different instance for site-to-site tunnels if you have more than one remote site.
Add QoS rules to ensure VPN traffic receives adequate bandwidth without starving other services.
Implement client-specific overrides ccd to provide different routes per client device.
Consider running a small, dedicated device for WireGuard if you need higher performance. EdgeRouter X isn’t optimized for WireGuard by default, but you can run it on a connected device that supports WireGuard and route traffic appropriately.

Alternatives and complementary approaches

WireGuard option: WireGuard is faster and simpler in many cases, but EdgeRouter X’s OpenVPN focus is more mature. If you need WireGuard, you may use a separate device e.g., a Raspberry Pi or small PC to host WireGuard and route traffic through EdgeRouter X for extra security or to test performance.
Site-to-site VPN: If you need to connect multiple locations, you can run OpenVPN or IPsec on both ends with the EdgeRouter X at each site and route traffic between sites securely.
Remote access benefits: OpenVPN on EdgeRouter X is a good balance of control, cost, and simplicity for individual users and small networks.

Data and statistics to guide expectations

OpenVPN remains widely used in home and small business VPN deployments due to its robust cross-platform support and mature feature set.
WireGuard has seen rapid adoption in consumer VPN offerings thanks to its speed and simplicity, but OpenVPN remains a staple for compatibility and deep customization.
For EdgeRouter X, expect reliable OpenVPN performance when tuned with reasonable cipher choices and hardware limits. real-world throughput will vary based on client devices and network conditions.
