EdgeRouter models can handle OpenVPN well when configured properly. The setup is more involved than consumer-grade VPN apps, but the payoff is a robust, customizable solution that you own completely.
Section: Prerequisites and planning
Before you dive in, gather and plan: How to use a VPN with Microsoft Edge on iPhone and iPad for Enhanced Privacy
- Hardware: EdgeRouter model ER-6P, ER-Lite, ER-4, etc.. Ensure you have a spare Ethernet port for the VPN server’s internal network if needed.
- Firmware: Latest EdgeOS firmware with OpenVPN support. Check for known issues on Ubiquiti forums.
- DNS: A static IP from your ISP or a dynamic DNS DDNS service so you can reach your EdgeRouter from outside your network.
- Backups: A backup plan for your EdgeRouter configuration before making changes.
- Certificates: A plan for creating a Certificate Authority CA, server certificate, and client certificates.
Section: Certificate authority and server setup step-by-step
- Create a CA and sign certificates
- Generate a private key and certificate for the CA.
- Create a server certificate signed by the CA.
- Create client certificates for each user or device.
- Prepare the OpenVPN server configuration
- Choose the VPN network range e.g., 10.8.0.0/24 and a tunnel network.
- Select the protocol UDP is common for performance and port 1194 is standard.
- Enable TLS authentication if desired, and set encryption parameters e.g., AES-256-CBC with SHA-256.
- Pick a realm within the EdgeRouter network for the VPN’s virtual interface often TUN mode.
- Install and configure OpenVPN on EdgeRouter
- Access the EdgeRouter via SSH or the UI.
- Install OpenVPN components if not present some EdgeOS builds include OpenVPN by default; otherwise, install the necessary packages.
- Create server configuration file with the appropriate directives:
- server 10.8.0.0 255.255.255.0
- ifconfig-pool 10.8.0.2 10.8.0.254
- push “redirect-gateway def1”
- push “dhcp-option DNS 8.8.8.8”
- keepalive 10 120
- cipher AES-256-CBC
- user nobody
- group nogroup
- status openvpn-status.log
- verb 3
- Wire up routing and IP forwarding
- Enable IP forwarding in the kernel net.ipv4.ip_forward=1.
- Set up NAT rules so traffic from VPN clients can reach the internet and your LAN as needed.
- Firewall rules
- Create a security policy to allow OpenVPN UDP/1194 in.
- Ensure NAT is correctly configured for traffic from the VPN network.
- Limit access to trusted subnets if possible for added security.
- Start and test the OpenVPN server
- Start the OpenVPN service and check logs for any errors.
- Test a local LAN client to ensure the tunnel comes up and routing works.
Section: Firewall, NAT, and port considerations
- Port considerations: If your ISP blocks UDP 1194, you can switch to TCP 443 though OpenVPN over TCP can be slower. Some admins hide OpenVPN traffic behind TLS on port 443 for better traversal.
- NAT vs bridged mode: OpenVPN often uses NAT masquerading to allow VPN clients to reach the internet. If you need devices on the VPN to appear on the LAN directly, you may explore bridged configurations, but NAT is simpler and more common for home setups.
- Firewall zoning: Put the VPN interface in a separate zone and restrict inbound traffic to only what’s needed for your use cases.
Section: Client configuration Windows, macOS, iOS, Android
Create client configuration files .ovpn and certificates for each user. Here’s what the client setup typically includes:
- Client certificates: Client cert and key files
- CA certificate
- TLS-auth key if you enabled TLS authentication
- Server address: your DDNS or static IP with the OpenVPN port
- Protocol and cipher: UDP, AES-256-CBC, etc.
- Redirect-gateway or route-push options if you want all traffic to route through VPN
Windows
- Install OpenVPN client software
- Import the client .ovpn profile
- Connect and verify the tunnel status
MacOS Vpn not working with sky broadband heres the fix: practical tips, troubleshooting, and setup tweaks
- Use Tunnelblick or Viscosity with the .ovpn profile
- Connect and confirm the VPN interface appears tun0 or utun
IOS and Android
- Use the official OpenVPN Connect app
- Import the .ovpn profile via email, cloud drive, or a QR code
- Establish the VPN connection and test reachability to your home network resources
Section: Testing and verification
- Verify a public IP change: Check your IP address on an external site to confirm it shows your VPN exit address.
- Internal reachability: Ping devices on your LAN e.g., NAS, printer to confirm routing works.
- DNS leakage test: Use a tool or site to ensure DNS queries aren’t leaking outside the VPN tunnel.
- Bandwidth testing: Compare upload/download speeds with VPN on and off to gauge the impact.
Section: Security best practices
- Use strong certificates and rotate them as needed.
- Enforce TLS authentication if possible to mitigate certain attack vectors.
- Limit VPN access to only required subnets; avoid broad access by default.
- Keep EdgeRouter firmware up-to-date with security patches.
- Regularly review VPN logs for unusual activity.
Section: Maintenance and ongoing care
- Schedule periodic certificate renewals and revocation checks.
- Back up the EdgeRouter configuration after successful VPN deployment.
- Monitor VPN performance and adjust MTU/mss-clamping if you notice connectivity issues.
- Document your client profiles, including which devices have which certificates and where they’re used.
