Why use ExpressVPN with OpenVPN?

OpenVPN is a flexible, widely supported VPN protocol that provides strong encryption and good compatibility with many devices. ExpressVPN’s OpenVPN configuration files give you more granular control than the standard ExpressVPN apps, which is useful for:

• Custom routing and split tunneling scenarios
• Devices that don’t support the ExpressVPN app
• Environments requiring specific cipher or TLS configurations
• Situations where you want to audit or customize DNS settings

However, for most users, the ExpressVPN app is a simpler, more integrated experience with automatic server selection, smart location switching, and built-in features like a kill switch. This guide focuses on the OpenVPN method so you have a fallback or alternative when the app isn’t ideal.

Prerequisites

• An ExpressVPN account active subscription
• A device capable of running OpenVPN or a compatible OpenVPN client
• Administrative access on the device
• A working internet connection
• Basic familiarity with file transfers and command-line interfaces for some steps

Getting the OpenVPN configuration files from ExpressVPN

1. Sign in to your ExpressVPN account on the web: expressvpn.com
2. Navigate to the OpenVPN/VPN Configuration section. Look for OpenVPN protocol and server lists.
3. Download the .ovpn configuration files for the servers you want to use. You’ll typically get separate files for UDP and TCP variants, plus separate files for different locations and ports.
4. If you want to tunnel DNS or use custom DNS, download any ancillary files like DNS configuration or TLS-auth files provided by ExpressVPN.
5. Save the files in a dedicated folder on your device for example, C:\ExpressVPN\OpenVPN on Windows or /home/ YourUser/OpenVPN on Linux/macOS.

Tip: Keep a small note with each file’s target country and server name to keep things organized.

Windows: OpenVPN Client tap/tun setup

• Recommended client: OpenVPN Connect or the official OpenVPN GUI
• Steps:
  1. Install OpenVPN client from openvpn.net
  2. Create a folder for your .ovpn files as prepared earlier
  3. Import a server file: In OpenVPN GUI, right-click the icon in the system tray, choose Import, and select your .ovpn file
  4. If the server requires TLS-auth or a certificate file, place these alongside the .ovpn file and reference them in the config as needed often included by ExpressVPN
  5. Enter your ExpressVPN credentials when prompted if the config uses a username/password approach
  6. Connect and verify your IP address using ipinfo.io or similar service

Tips:

• Use UDP variant by default for better performance; TCP is more reliable on poor networks
• If you see TLS handshake errors, ensure the TLS-auth file is correctly referenced or remove it if not provided
• Run the OpenVPN client as Administrator to avoid permission issues

macOS: OpenVPN with Tunnelblick or OpenVPN Connect

• Steps:
  1. Install Tunnelblick free or OpenVPN Connect from the Mac App Store
  2. Place your downloaded .ovpn file in a new folder
  3. Open Tunnelblick and drag the .ovpn file into the “I have configuration files” area
  4. Authenticate with your macOS password to install the configuration
  5. Connect using the Tunnelblick icon in the menu bar
  6. Check your IP using a site like ipinfo.io and verify DNS is resolving through VPN by visiting a non-local site

Tips: Does Total AV Have a VPN Everything You Need to Know

• If you’re using DNS over TLS or custom DNS options, make sure the macOS DNS settings are aligned to avoid leaks
• Use the “prefer UDP” server variant for faster speeds

Linux: OpenVPN client setup

• Steps example for Ubuntu/Debian:
  1. Install OpenVPN: sudo apt update && sudo apt install -y openvpn
  2. Create a directory for your OpenVPN configs: sudo mkdir -p /etc/openvpn/expressvpn
  3. Copy your downloaded .ovpn file into /etc/openvpn/expressvpn and rename if needed
  4. Start the tunnel: sudo openvpn –config /etc/openvpn/expressvpn/yourfile.ovpn
  5. Enter credentials when prompted and monitor the console for the “Initialization Sequence Completed” line
  6. Verify connectivity: curl ifconfig.me to confirm your public IP and dig +short @resolver1.opendns.com myip.opendns.com for DNS
  7. Optional: Create a systemd service for auto-start on boot

Tips:

• For persistent connections, set up a systemd service: create a unit file that runs the OpenVPN process
• Ensure IP routing and DNS are directed through the VPN by using appropriate route-nopull or domain rules if you need split tunneling

iOS: OpenVPN Connect app

• Steps:
  1. Install OpenVPN Connect from the App Store
  2. Transfer the .ovpn file to your iPhone AirDrop, iCloud Drive, or email
  3. Open the .ovpn file with OpenVPN Connect or import via the app
  4. Add your ExpressVPN credentials if required
  5. Connect and verify your IP address in Safari or a test site

Tips:

• iOS tends to cache DNS, so give it a few seconds after connecting for DNS to fully route through the VPN
• Ensure the app has necessary permissions Background App Refresh, etc. for a reliable connection

Android: OpenVPN Connect app

• Steps:
  1. Install OpenVPN Connect from Google Play
  2. Transfer the .ovpn file to your device
  3. In OpenVPN Connect, import the .ovpn file
  4. Enter credentials if required and connect
  5. Verify your IP via a test site

Tips:

• Android devices sometimes prefer UDP for speed, but if you see packet loss, switch to TCP
• If you’re using a private DNS or DNS-over-TLS, ensure Android DNS settings won’t leak during VPN use

DNS, leaks, and kill switch considerations

• DNS leaks: Some configurations may still leak DNS requests if the DNS servers aren’t routed through the VPN. Use the OpenVPN directive to push DNS servers through the tunnel, or configure the device to use a VPN-provided DNS.
• Kill switch: Many OpenVPN clients support a kill switch, which blocks all traffic if the VPN drops. Enable this feature to prevent unprotected traffic. If your client doesn’t have a built-in kill switch, you can implement IPTables rules on Linux or rely on the app’s own protection on Windows/macOS.
• DNS over TLS: If you want extra privacy, consider enabling DNS over TLS in your OpenVPN config or use a reputable DNS provider that offers DNSSEC/DNS over TLS. Verify with a DNS leak test after connecting.

Performance optimization tips

• Choose nearby servers: For lower latency, pick servers that are geographically close to you while still meeting your content access needs.
• Prefer UDP where possible: UDP generally offers better speed, but if you’re on a flaky connection, switch to TCP.
• Split tunneling if available in your setup: Route only certain apps or destinations through VPN to improve speed and performance for non-critical traffic.
• Keep your OpenVPN software updated: Security fixes and performance improvements are common in newer releases.
• Verify MTU settings: If you notice packet fragmentation or connection instability, adjust MTU settings in your config commonly 1400-1500 for VPNs to reduce fragmentation.
• Use a reputable DNS provider: A clean, fast DNS reduces lookup times and reduces the chance of DNS-based delays.

Security considerations and best practices

• Use strong authentication if your OpenVPN config supports it certificates or TLS-auth
• Keep your credentials secure and do not reuse the same password across different services
• Regularly check for server updates and recommended configs from ExpressVPN
• If you suspect a compromised server, switch to another server location promptly
• Consider enabling a kill switch and DNS leak protection to prevent data exposure if the VPN drops

Advanced: routing and split tunneling configurations

• Split tunneling allows you to send only certain traffic through the VPN. This is useful for accessing geo-restricted content while browsing normally for non-sensitive traffic.
• In OpenVPN, you can push route configurations from the server or adjust client routing to direct specific IP ranges through the VPN.
• Example: Direct internal corporate resources through VPN while leaving general web traffic outside the tunnel.

Common issues and quick fixes

• Connection refused or TLS handshake failed: Check that you’re using the correct .ovpn file, the TLS-auth file if required is in place, and the server supports the chosen protocol UDP vs TCP.
• DNS leaks after connecting: Ensure DNS servers are pushed through the VPN or switch to a DNS provider that respects VPN routing. Double-check your OpenVPN config for any “dhcp-option DNS” lines and adjust if needed.
• Slow speeds: Try a different server, switch to UDP, or reduce encryption overhead by selecting a lighter cipher if possible only if security requirements permit.
• Automatic reconnect failing on Linux: Ensure your systemd service is configured correctly and that OpenVPN has the proper permissions to restart the service on failure.

Quick reference: sample configuration adjustments

• Basic UDP config simplified:
  • client
  • dev tun
  • proto udp
  • remote YOUR_SERVER_IP 1194
  • resolv-retry infinite
  • nobind
  • persist-key
  • persist-tun
  • cipher AES-256-CBC
  • auth SHA256
  • tls-auth ta.key 1
  • tls-client
  • remote-cert-tls server
  • compress lz4
  • verb 3
• If you need a TCP fallback:
  • replace proto udp with proto tcp-client
  • adjust port to 443 or a port that’s allowed by your network

Best practices for staying safe with OpenVPN

• Always verify server fingerprints when you first connect to avoid man-in-the-middle attacks
• Use a reputable server list and avoid unknown or untrusted servers
• Regularly update all VPN-related software and keep an eye on security advisories
• Consider using a separate, dedicated user account for VPN connections if supported
• For extra privacy, pair with a privacy-conscious browser and a reputable antivirus

Performance comparison: OpenVPN vs ExpressVPN native apps

• OpenVPN OpenVPN protocol:
  • Pros: High configurability, broad compatibility, strong encryption options
  • Cons: Setup complexity, potential DNS leaks if not configured properly
• ExpressVPN native apps:
  • Pros: Easy setup, automatic server selection, smart location features, built-in kill switch, typically lower overhead for most users
  • Cons: Less granular control over routing and advanced network configurations

If you’re after speed and simplicity, the native ExpressVPN apps often win. If you need precise control, OpenVPN gives you that flexibility, at the cost of a bit more hands-on setup.
