Generate CA, server, and client certificates

Install easy-rsa if not present the package name may vary by EdgeRouter version.
Initialize a new PKI:
- ./easyrsa init-pki
- ./easyrsa build-ca nopass
Build the server certificate and key:
- ./easyrsa build-server-full server nopass
Build client certificates for each user or device:
- ./easyrsa build-client-full client1 nopass
Generate Diffie-Hellman parameters:
- ./easyrsa gen-dh

Create server configuration file

Create /config/vpn/openvpn/server.conf with content similar to:
- port 1194
- proto udp
- dev tun
- ca /path/to/ca.crt
- cert /path/to/server.crt
- key /path/to/server.key
- dh /path/to/dh.pem
- server 10.8.0.0 255.255.255.0
- ifconfig-pool-persist /var/lib/openvpn/ipp.txt
- keepalive 10 120
- cipher AES-256-CBC
- auth SHA256
- topology subnet
- push “redirect-gateway def1”
- push “dhcp-option DNS 1.1.1.1”
- user nobody
- group nogroup
- persist-key
- persist-tun
- status /var/log/openvpn-status.log
- verb 3
- tls-auth /path/to/ta.key 0

Enable IP forwarding and firewall rules

sysctl -w net.ipv4.ip_forward=1
Add firewall rules to allow UDP 1194 inbound and VPN traffic:
- Allow: UDP 1194 from any to EdgeRouter public interface
- NAT: masquerade traffic from VPN subnet 10.8.0.0/24 to WAN

Configure OpenVPN client profiles

Create a .ovpn profile merging CA, cert, key, and ta.key:
- client
- dev tun
- proto udp
- remote YOUR_PUBLIC_IP 1194
- resolv-retry infinite
- nobind
- persist-key
- persist-tun
- cipher AES-256-CBC
- auth SHA256
- verb 3
- —–BEGIN CERTIFICATE—– … —–END CERTIFICATE—–
- —–BEGIN CERTIFICATE—– … —–END CERTIFICATE—–
- —–BEGIN PRIVATE KEY—– … —–END PRIVATE KEY—–
- —–BEGIN OpenVPN Static key V1—– … —–END OpenVPN Static key V1—–

Client testing

Import the .ovpn profile into your OpenVPN client on Windows, macOS, iOS, and Android.
Connect from a remote network and verify:
- Your IP address changes to the VPN’s network range.
- DNS queries resolve through the VPN no leaks.
- Access to internal resources e.g., a home NAS works as expected.

Optional: GUI-based management EdgeRouter OS

If you prefer GUI, many EdgeRouter devices let you manage VPN users and basic OpenVPN settings through the web interface. Check your firmware version for OpenVPN support in the UI.

Security best practices and tips

Use TLS-auth ta.key to add an additional HMAC signature layer to prevent TLS handshake attacks.
Select strong ciphers AES-256-CBC is a solid baseline; consider AES-256-GCM if supported.
Enforce client certificate authentication to ensure only authorized devices can connect.
Use a management network or VPN-only admin access to the EdgeRouter.
Regularly rotate certificates and keep your EdgeRouter firmware up to date.
Enable logging and monitor VPN connection attempts to detect brute-force activity.

Advanced configurations

Split tunneling vs. full tunneling:
- For split tunneling, push specific routes to the client to only send certain traffic through the VPN.
- For full tunneling, push the default gateway to the VPN so all traffic goes through the tunnel.
DNS considerations:
- Run a local DNS server behind the VPN to resolve internal names privately.
- Push public DNS services 1.1.1.1 or 9.9.9.9 to clients if privacy is a concern.
Client-specific overrides:
- Create per-client profiles with tailored routes or permissions.
High availability:
- If you have multiple EdgeRouter devices, consider a design for failover or load balancing for VPN connections.

Troubleshooting quick-start

Issue: Clients can connect but can’t access internal resources.
- Check internal routing: Ensure the VPN subnet routes to the LAN subnet.
- Verify firewall rules on EdgeRouter allow VPN traffic to the LAN.
Issue: DNS leaks detected.
- Ensure DNS servers are pushed to clients and that the client uses VPN DNS.
Issue: Connection drops or flaky stability.
- Review server logs for TLS errors or handshake issues.
- Check for NAT or firewall timeouts and adjust keepalive settings.
Issue: Clients cannot reach the EdgeRouter management UI after VPN connect.
- Use split tunnel with a route to LAN, ensuring VPN doesn’t hijack all routes if you still need local access.

Performance considerations

VPN throughput depends on your EdgeRouter model and CPU. Lightweight EdgeRouters can handle a handful of concurrent connections, but higher-end models handle more connections with better encryption ciphers.
Turn off unnecessary services to free CPU cycles for VPN processing.
Consider using UDP as the transport protocol for better performance and lower latency.

Do I need a static IP for OpenVPN on EdgeRouter?
A static IP makes remote access straightforward, but you can also use dynamic DNS if your public IP changes.
How do I generate certificates for OpenVPN?
You typically use a PKI tool like Easy-RSA to create a CA, server certificate, and client certificates, then sign and export them for use in EdgeRouter and clients.
Should I use TLS-auth?
TLS-auth adds an extra layer of security by authenticating TLS packets, which helps protect against certain types of TLS attacks.
How do I test the VPN connection?
Install the OpenVPN client on a remote device, import the profile, connect, and verify you can reach internal resources and that your public IP reflects the VPN network.

How can I verify there are no DNS leaks?
Test your DNS queries when connected to the VPN using online DNS leak test tools, and ensure your VPN config pushes a private DNS server to clients.
Can I route all traffic through the VPN?
Yes, you can push a default route to VPN clients to ensure all their traffic goes through the VPN tunnel.
Is split tunneling safer than full tunneling?
Split tunneling reduces VPN load and can improve performance but requires careful configuration to avoid exposing sensitive resources via the public network.
How do I rotate certificates?
Revoke old certificates, generate new keys, and redistribute updated client profiles, then test connections to ensure everything still works.
