Section 1: EdgeRouter X and VPN options at a glance

• What you’re working with: EdgeRouter X is a compact router that runs EdgeOS, a fork of VyOS-inspired firmware. It’s designed for small-to-medium networks and can handle multiple VPN tunnels when configured properly.
• VPN options you’ll likely use:
  • WireGuard: Known for speed and simplicity, lightweight cryptography, and easy client management.
  • OpenVPN: Broad compatibility, strong security, and robust client options. a good fallback when devices don’t support WireGuard.
  • IPsec: Common in enterprise environments. can be a solid option for site-to-site networks or legacy devices.
• Real-world expectations: Even on budget hardware like the ER-X, VPN throughput depends on the tunnel type, the host CPU, and the tunnel configuration. In practice:
  • WireGuard on a capable EdgeRouter setup frequently delivers hundreds of Mbps on a home connection, sometimes approaching the line rate of the device with overhead.
  • OpenVPN typically sits lower due to its heavier cryptography and TLS overhead, often in the tens to low hundreds of Mbps depending on cipher choices and CPU.
• Why VPN on EdgeRouter makes sense: You keep your LAN traffic private without routing all traffic through a single PC or an external box. It’s also easy to isolate VPN features behind your firewall rules for better security posture.

Section 2: Why you’d want to run a VPN on EdgeRouter X

• Centralized control: VPN access for all devices in your network, with consistent firewall and NAT rules.
• Site-to-site possibilities: If you have a second location or a partner network, a site-to-site VPN lets you connect networks securely without exposing each device individually.
• Access control and auditing: You can enforce two-factor authentication on OpenVPN clients or use WireGuard’s simple key-based approach to manage who can connect.
• Privacy and security: Encrypting traffic from your home or office protects sensitive data on public networks and when using remote management tools.
• Budget-friendly flexibility: EdgeRouter X gives you VPN capabilities without the need for expensive hardware, and you can expand as your network grows.

Section 3: VPN protocol showdown for EdgeRouter X

• WireGuard
  • Pros: High performance, minimal codebase, easy key management, fast handshakes.
  • Cons: Newer in some jurisdictions. may require more manual client management if you’re not using a centralized key system.
• OpenVPN
  • Pros: Mature ecosystem, broad client support across Windows, macOS, Linux, iOS, and Android. strong flexibility with TLS configs.
  • Cons: Slightly heavier on CPU. speed can be lower than WireGuard on the same hardware.
• IPsec
  • Pros: Great for site-to-site and interoperability with other VPN gear. mature and well-supported.
  • Cons: Complex setup. can be slower depending on algorithms and device support.
• Practical takeaway: For most ER-X users, start with WireGuard for speed and simplicity. Use OpenVPN when you need broader compatibility older devices, certain corporate apps. IPsec shines in site-to-site contexts where you already have IPsec devices at both ends.

Section 4: Getting WireGuard up on EdgeRouter X step-by-step
Note: WireGuard on EdgeRouter X is typically configured via EdgeOS CLI or GUI. Below is a practical, high-level workflow you can adapt. Always backup before major config changes.

1. Prep and plan

• Decide your internal network for VPNs example: 10.200.200.0/24 for VPN peers.
• Generate key pairs for peers on each device you’ll use a private and public key. keep private keys secret.
• Choose an allocated IP range for the VPN tunnel like 10.13.13.0/24 for wg0.

2. Create a WireGuard interface

• In GUI: Network > Interfaces > Add Interface > WireGuard > wg0
• In CLI example, adapt as needed:
  • set interfaces wireguard wg0 address 10.13.13.1/24
  • set interfaces wireguard wg0 private-key

3. Add peers

• For each remote peer, you’ll add the peer’s public key and allowed IPs
  • set interfaces wireguard wg0 peer allowed-ips 10.13.13.2/32
  • set interfaces wireguard wg0 peer endpoint :
  • set interfaces wireguard wg0 peer persistent-keepalive 25

4. Enable routing for VPN networks

• set protocols static route 0.0.0.0/0 next-hop 10.13.13.2 if you want all remote traffic tunneled. tailor to your needs
• set service ssh on your management interface if you’re doing remote config, but practice safe rules

5. Firewall and NAT considerations

• Create a VPN-specific firewall rule set to allow traffic from the VPN network to your LAN and vice versa
• If devices behind the ER-X should access the VPN, ensure NAT is configured for VPN-originating traffic if needed

6. Test and verify

• Bring up wg0 and verify peer connectivity
• Check the interface status and peer handshakes
• Verify traffic flow with traceroute/ping from a VPN-connected client to LAN endpoints

7. Client-side setup example

• Install a WireGuard client on your device
• Add a tunnel with the ER-X’s public key as the peer, and assign the appropriate allowed IP route
• Bring the tunnel up and test access to LAN resources and the Internet depending on your routing choice

8. Maintenance tips

• Regularly rotate keys if you’re using a shared VPN hub
• Keep EdgeOS updated to benefit from WireGuard improvements and security fixes

Section 5: OpenVPN on EdgeRouter X step-by-step, high-level
OpenVPN is the veteran choice with broad device compatibility. Here’s a practical workflow you can adapt:

1. Prepare the server and client certificates

• Use EasyRSA or your preferred PKI approach to generate a CA, server certificate, and client certificates
• Export client configurations to .ovpn files for easy import on devices

2. Create an OpenVPN server on EdgeRouter X

• In GUI: Services > VPN > OpenVPN Server
• In CLI: define server tunnel details, port commonly 1194, protocol UDP, and network range for VPN clients e.g., 10.8.0.0/24

3. Configure firewall rules

• Allow VPN traffic UDP 1194 by default and route VPN clients to your LAN as needed
• Ensure NAT rules are set so VPN clients can reach the Internet and LAN resources

4. Client configuration

• Load the .ovpn file on clients, ensure the server address, port, and TLS/auth settings match
• Test connectivity to LAN resources and Internet

5. Troubleshooting OpenVPN

• If you run into TLS handshake issues, re-check certificates and CA configuration
• Check log files for authentication errors and verify that firewalls aren’t blocking VPN ports

Section 6: Site-to-site VPN with EdgeRouter X
A site-to-site VPN connects two networks securely, great for a small branch office or partner network.

1. Decide on a tunnel topology

• Typical: a single tunnel with a private subnet for each side e.g., 10.0.1.0/24 on Site A, 10.0.2.0/24 on Site B

2. WireGuard site-to-site recommended for new deployments

• Configure wg0 on both sides with corresponding private keys, peers, and allowed-ips
• Route traffic from the internal subnets across the tunnel
• Ensure keepalive and MTU settings are tuned to your network

3. OpenVPN site-to-site

• Define server on one end, and client configuration on the other end as a “site-to-site” tunnel
• Push routes to target subnets so hosts know to reach the remote network through the VPN tunnel

4. Firewall and NAT alignment

• Lock down inbound connections to VPN endpoints
• Allow VPN subnets to access their local networks and necessary remote subnets

5. Validation

• Test pings across sites, verify service accessibility, and ensure the VPN is persistent across restarts

Section 7: Performance tuning and security best practices

• Use WireGuard where possible for speed and simplicity
• Keep firmware up to date: EdgeOS updates often include important security and performance improvements
• Harden firewall rules: drop unnecessary traffic, limit remote admin exposure
• Use strong, unique keys. rotate keys periodically for security
• For OpenVPN, choose modern ciphers and enable TLS 1.2 or higher where supported
• Consider enabling QoS or traffic shaping to preserve latency for VPN clients
• Disable IPv6 on VPN tunnels if you don’t need it to reduce potential attack surfaces
• Regularly monitor VPN connections and review logs for unusual activity
• Make backups of your EdgeRouter configuration before big changes

Section 8: Common pitfalls and quick fixes

• Firewall misconfig blocking VPN traffic: double-check rules for the VPN subnet
• NAT hairpinning issues: ensure correct NAT rules so internal clients can reach internal resources via VPN
• Mismatched keys or endpoints in WireGuard: keep a tidy, documented key management process
• Client connectivity failures: verify client config, endpoints, allowed-ips, and keepalive settings
• Performance drops after updates: review crypto settings and disable unneeded services to free CPU headroom

Section 9: Tools, resources, and best practices

• Always keep a local, secure backup of your EdgeRouter config
• Maintain a small, documented change log for VPN configurations
• Use a dedicated management computer or device for testing configurations before pushing to production
• Regularly review VPN user access and remove stale peers
• For more secure remote access, consider MFA options supported by your OpenVPN setup
