What is OpenVPN on EdgeRouter?

• OpenVPN on EdgeRouter lets you host a VPN server directly on your home or small-business router, enabling remote clients to connect securely to your local network over the internet.
• EdgeRouter devices run EdgeOS, which includes built-in OpenVPN server capability, certificate management, and firewall integration.
• With OpenVPN, you can choose between full-tunnel all traffic goes through the VPN or split-tunnel only specific traffic goes through the VPN, manage client access, and enforce encryption standards without needing a separate server.

Why use OpenVPN on EdgeRouter?

• Convenience: Run a VPN server at home or office without extra hardware.
• Control: You own the certificate authority, server, and client configs—no third-party dependency for internal access.
• Compatibility: OpenVPN clients are available on Windows, macOS, Linux, iOS, and Android.
• Security tunings: TLS authentication, certificate-based auth, and modern ciphers help protect traffic between client devices and your network.
• Cost-effective: If you already own an EdgeRouter, OpenVPN comes built-in, reducing extra expenses.

Requirements

• EdgeRouter device running a supported EdgeOS version 2.x series is common for OpenVPN support.
• A registered domain or dynamic DNS setup if you want to reach the VPN server from the internet via a friendly hostname.
• A private LAN range for your VPN e.g., 10.8.0.0/24 that won’t clash with your existing LAN.
• Certificates: CA certificate, server certificate, server key, and client certificates. You can generate these via EdgeOS Certificate Manager or your own CA.
• Firewall rule adjustments to allow VPN traffic usually UDP 1194 by default, but you can customize.
• Optional: TLS authentication key ta.key for an extra layer of security.
• Network access: Ensure edge router can route to the LAN behind it and, if needed, set appropriate NAT rules for VPN clients.

Step-by-step setup GUI method

This section covers configuring OpenVPN on EdgeRouter via the Web UI EdgeOS, which many users find approachable.

1 Prepare certificates CA, server, and client

• OpenVPN relies on certificates. In EdgeOS, use the built-in Certificate Manager or upload pre-generated certs.
• Create a Certificate Authority CA and issue a server certificate with a TLS key server cert and key.
• Create a client certificate for each remote user or device you plan to connect.

Tips:

• Keep your CA private and secure.
• Use at least a 2048-bit RSA or, preferably, a 4096-bit RSA or ECC-based certs for better security.

2 Enable and configure the OpenVPN server

• Log into the EdgeRouter Web GUI.
• Go to VPN > OpenVPN Server the exact navigation can vary slightly by firmware. Click Add or Enable.
• Configure the server:
  • Server mode: Server
  • Protocol: UDP recommended for speed and reliability or TCP
  • Port: 1194 or another port if you have a reason to change it
  • Local IP/Network: Define your VPN’s internal pool, for example 10.8.0.0/24
  • TLS: Enable TLS server. provide ca-cert, server-cert, and server-key
  • TLS-auth: Optional but recommended. provide ta.key and set 0 for the server
  • Cipher: Choose a modern cipher like AES-256-CBC or AES-256-GCM if supported
  • Push options: If you want to push DNS e.g., 1.1.1.1 and a default gateway, add pushes like redirect-gateway def1 and dhcp-option DNS 1.1.1.1
  • Client address pool: e.g., 10.8.0.0/24
  • Server topology: subnet
• Save or apply the settings.

3 Create VPN users/clients

• In the certificate manager, create a client certificate for each user or device that will connect.
• Export the client profile or copy the client certificate and key into individual client config files.

4 Configure firewall and NAT

• Add a firewall rule to allow inbound VPN traffic:
  • Source: WAN
  • Destination: EdgeRouter VPN port e.g., UDP 1194
  • Action: Accept
• Ensure NAT is not interfering with VPN traffic if you want VPN clients to reach the internet through the VPN full-tunnel or your LAN resources split-tunnel scenarios.
• If you’re using a separate VLAN for VPN clients, map the VPN network 10.8.0.0/24 to the appropriate interfaces.

5 Export client configuration

• EdgeOS can export a ready-to-use OpenVPN client config .ovpn for Windows/macOS/Linux.
• Save the .ovpn file per client, or extract the necessary certificate/key blocks and embed them into a single file.

6 Test locally and remotely

• On a client device, import the .ovpn file and attempt a connection.
• Verify the VPN connection status in EdgeOS and ensure clients get an IP from the VPN pool e.g., 10.8.0.x.
• Check that traffic routes as expected gateway set to VPN, DNS resolution through VPN if configured.

7 Troubleshooting tips GUI

• If clients can connect but cannot reach LAN resources, double-check LAN firewall rules and client-side routes.
• If you get certificate errors, confirm that the CA, server cert, and client certs are correctly issued and installed.
• If the tunnel won’t start, verify the TLS-auth ta.key presence and correct orientation 0/1 for server/client.
• Ensure the EdgeRouter’s NAT rules don’t overlap with the VPN’s IP range.

Step-by-step setup CLI method

If you’re comfortable with the command line, here’s a high-level outline you can adapt. Exact syntax can vary by firmware version, so refer to your EdgeOS version’s docs for precise commands. Best vpn edge

1 Create CA and certificates

• Generate CA and server certificates or import them if you already have them.
• Place ca.crt, server.crt, and server.key under /config/auth/ or an equivalent cert folder.

2 Configure the OpenVPN server

• Enter configuration mode and apply settings:
  • set vpn openvpn enable
  • set vpn openvpn server mode server
  • set vpn openvpn server protocol udp
  • set vpn openvpn server port 1194
  • set vpn openvpn server dev tun
  • set vpn openvpn server localip 10.8.0.1
  • set vpn openvpn server push “redirect-gateway def1”
  • set vpn openvpn server push “dhcp-option DNS 1.1.1.1”
  • set vpn openvpn server tls-server
  • set vpn openvpn server ca-cert /config/auth/ca.crt
  • set vpn openvpn server server-cert /config/auth/server.crt
  • set vpn openvpn server server-key /config/auth/server.key
  • set vpn openvpn server tls-auth ta.key 0
  • set vpn openvpn server cipher AES-256-CBC

3 Create client profiles

• For each client, generate a client certificate and assemble a .ovpn:
  • set vpn openvpn client cert /config/auth/clientX.crt
  • set vpn openvpn client key /config/auth/clientX.key
  • Export the combined client config if your EdgeOS version supports an export command.

4 Firewall and NAT rules CLI

• set firewall name VPN-INPUT default-action drop
• set firewall name VPN-INPUT rule 10 protocol udp
• set firewall name VPN-INPUT rule 10 destination port 1194
• set firewall name VPN-INPUT rule 10 action accept
• set interfaces openvpn-server firewall local VPN-INPUT
• commit and save

5 Test and verify

• Start the OpenVPN server service
• Connect a client using the exported .ovpn or the built-in client
• Confirm the VPN assigns 10.8.0.x and you can reach LAN resources or the internet depending on your setup

Note: CLI commands above are representative. Adjust paths and values to your environment. Always back up your EdgeRouter config before major changes.

Client access, DNS, and routing tips

• DNS: Push a private DNS server e.g., your home DNS or 1.1.1.1 to ensure name resolution is VPN-protected and stable.
• Split tunneling: If you don’t want all traffic to go through the VPN, adjust push-route and client side config to only route specific subnets or destinations via VPN.
• DNS leaks: Use a VPN DNS to avoid leaks. If you’re using local DNS resolvers, ensure the VPN client config forces DNS through the VPN.
• Privacy and logs: Keep the CA and server private, rotate keys periodically, and review firewall rules to minimize exposure.
• TLS-auth ta.key: Use TLS-auth if possible to mitigate certain types of attacks. Generate ta.key and include it in both server and client configs.

Performance and security considerations

• Use AES-256-CBC or AES-256-GCM when available for encryption, balancing security with performance on your hardware.
• Choose UDP over TCP for OpenVPN in most scenarios to reduce latency. TCP can be more reliable in lossy networks but often adds overhead.
• Keep EdgeRouter firmware up to date. security patches can affect OpenVPN reliability and performance.
• For small networks, a 1 Gbps EdgeRouter can comfortably handle multiple concurrent VPN clients. heavy client loads may want to monitor CPU load and tweak the number of concurrent tunnels.
• Regularly review and prune client certificates. remove certificates for users who no longer need access.

Advanced topics

• Split tunneling: Configure client-side or server-side policies to route only designated subnets via VPN, keeping general internet traffic direct to your ISP.
• Client-specific overrides: Push routes that let certain clients reach specific internal resources while leaving others as standard VPN connections.
• Multi-site VPN: If you have multiple remote sites, set up site-to-site tunnels in addition to remote access for broader network access.
• Certificate lifetimes: Set reasonable expiration dates for CA, server, and client certs. automate renewal where possible to avoid downtime.
• High availability: For critical uses, consider pairing EdgeRouter devices in a high-availability HA setup for VPN continuity.

Security best practices

• Use certificate-based authentication with TLS and TLS-auth ta.key to harden the VPN.
• Enforce strong passwords on client certificates and disable unused accounts.
• Limit VPN access by IP or subnet on the WAN firewall rules to reduce exposure to attacks.
• Regularly back up EdgeRouter configurations and certificates.
• Monitor VPN login activity and enable logging to detect suspicious access attempts.

Maintenance and updates

• Periodically review OpenVPN configuration for compatibility with new client OS versions.
• Update EdgeRouter firmware to benefit from security and performance improvements.
• Rotate server and client certificates on a schedule that fits your security policy.
• If you notice performance degradation, profile VPN client connections, check CPU usage, and consider splitting traffic or upgrading hardware.
