Prerequisites and planning
Before you start, make sure you have:

A MikroTik router running RouterOS with admin access
OpenVPN server details: server address, port, and protocol TCP/UDP, and the server’s certificate authority
Client certificate and key, or a username/password setup if your OpenVPN server supports it
A stable internet connection on the MikroTik router
A basic idea of your LAN IP scheme to avoid conflicts

If you’re planning to use a VPN for privacy or to access a remote network, set expectations for latency and throughput. OpenVPN over UDP generally provides better performance, but some servers require TCP for reliability. If you’re unsure, test both and choose what works best for your environment.

Certificates and keys
Most OpenVPN servers require certificates. Here’s a quick checklist:

CA certificate ca.crt
Client certificate client.crt
Client key client.key
Optional: TLS-auth key ta.key for an extra layer of security

If you’re not using certificates and instead rely on username/password, MikroTik supports that too, but certificate-based setups are common for stronger security. Keep your keys secure and export them to the MikroTik device in a safe, accessible way.

MikroTik OpenVPN client setup step-by-step
Note: Steps assume you’re using RouterOS v7 or later. The UI labels may differ slightly in older versions, but the flow is the same. Does Proton VPN Have Dedicated IP Addresses Everything You Need To Know

Access your MikroTik router

Connect to the router via Winbox, WebFig, or SSH.
Log in with an account that has admin privileges.

Import certificates if using certificate-based OpenVPN

Go to System > Certificates.
Import CA certificate ca.crt as a CA certificate.
Import Client certificate client.crt and client key client.key as a client certificate.
If you have ta.key, you’ll import it as an TLS key.

Create OpenVPN client interface

Go to PPP > Interfaces.
Click the “+” and choose OpenVPN Client.
Name the interface e.g., openvpn-client.

Configure the OpenVPN client

Server: enter the server address provided by your VPN server e.g., vpn.yourserver.com.
Port: input the server port commonly 1194 or another port your server uses.
Mode: ip
User: if you’re using a certificate-based setup, leave blank or input the username if your server requires it.
Password: leave blank for certificate-based authentication.
Profile: create or select a profile that matches your authentication method.

Authentication and encryption

TLS Authority: select the CA certificate you imported if required by your server.
Client certificate: select the client certificate you imported.
TLS key: if you have ta.key, configure it according to RouterOS docs often under TLS Auth or TLS Key fields.

Advanced options as needed

Verify server certificate: enable if your server provides a cert and you want to enforce it.
Compression: disable unless your server explicitly requires it to reduce overhead and potential vulnerabilities.
Dead Peer Detection DPD: enable with an appropriate interval, e.g., 15 seconds, to maintain a stable connection.
Reconnect: set to always or on connection loss to ensure automatic recovery.

Add a route-based VPN optional, depending on your setup

If your OpenVPN server pushes routes, MikroTik will automatically learn them once connected.
If you need to specify local LAN routes, you can add static routes to route traffic through the VPN tunnel.

Apply and test

Apply the configuration and wait for the VPN client to connect.
Check the status in PPP > Interfaces. The OpenVPN client should show as connected with a public IP from the VPN server.
You can test connectivity by pinging a remote host accessible through the VPN, or by visiting an IP test site from a device on your LAN.

Networking and routing considerations

Default route: Decide whether you want all traffic to go through the VPN kill-switch style or only specific subnets. If you set the VPN as the default route, all traffic will pass through it unless you add exceptions.
Split tunneling: To selectively route only certain destinations through the VPN, add static routes for those destinations, pointing to the VPN interface as the gateway.
DNS: Use the VPN-provided DNS or a trusted DNS to prevent DNS leaks. MikroTik can set DNS servers on the VPN interface or use a DNS forwarder on the LAN.
Firewall rules: Ensure you allow VPN traffic and allow traffic from LAN to VPN and back, while restricting unnecessary access. A minimal, tight firewall improves security.

DNS and leak protection

DNS leaks happen when DNS requests bypass the VPN. To prevent this:
- Point clients to DNS servers provided by the VPN or set DNS servers on the VPN interface.
- Ensure your firewall blocks DNS requests not going through the VPN until the VPN is up.
- Consider a DNS over TLS or DNS over HTTPS setup on clients if you need extra privacy for end devices behind the MikroTik.

Security and best practices

Use certificate-based authentication when possible for stronger security.
Enable TLS-auth or TLS-crypt if your server supports it to add an additional HMAC layer.
Keep your RouterOS up to date with the latest security patches.
Regularly rotate certificates and credentials and monitor VPN logs for unusual activity.
Implement a kill switch on the MikroTik side by blocking traffic to the internet if the VPN tunnel is down advanced, but effective.

Performance optimization

Choose a VPN protocol suitable for your needs. OpenVPN over UDP is typically faster than TCP, but some networks perform better with TCP.
Adjust MTU settings if you notice fragmentation or connection instability.
If you’re on a busy LAN, consider setting a dedicated CPU-core affinity for VPN processes if your MikroTik device supports it.
Monitor CPU and RAM usage to ensure the router isn’t overburdened by VPN processing.

If the VPN won’t connect:
- Double-check server address, port, and protocol.
- Confirm certificate validity and that the CA, client cert, and key match what the server expects.
- Check the DPD settings and server logs for hints.
If you have intermittent connectivity:
- Verify stability of the internet connection to the MikroTik.
- Review MTU settings and try lowering MTU by a small amount to reduce fragmentation.
If DNS leaks occur:
- Verify the DNS servers used by the VPN and ensure DNS requests from LAN devices go through the VPN.
- Use DNS over TLS or a secure DNS service if available.
If traffic routing isn’t what you expect:
- Confirm whether you’re using a default route through the VPN or split tunneling.
- Inspect routes and firewall rules to ensure no unintended exceptions exist.

Advanced scenarios

Multi-client OpenVPN: If you’re hosting a VPN on a server that supports multiple client certificates, configure each client with its own certificate pair and manage them via the MikroTik certificate store.
Combine with other VPNs: Some users run a secondary VPN for specific devices. Be mindful of routing and potential conflicts.
Redundancy: For critical networks, set up a secondary OpenVPN client or another VPN type as a failover. MikroTik can handle multiple VPN clients to switch over automatically if one fails.

NordVPN integration note
If you’re considering using a well-known consumer VPN service to secure traffic from your MikroTik, you can leverage NordVPN or similar providers. NordVPN offers reliable servers with broad coverage, and their service often includes dedicated guides for OpenVPN on various routers. For a seamless experience, you can follow their OpenVPN setup instructions and then adapt them to MikroTik’s OpenVPN client configuration. If you want a quick way to add extra privacy and security for your entire network without manual per-device configuration, NordVPN can be a solid choice.

Performance testing and validation

Test after establishing the VPN: run a simple throughput test from a LAN device to an internet destination, compare before and after enabling the VPN, and note any degradation.
Test DNS resolution from a LAN device with and without the VPN: ensure no leaks and verify that DNS queries route through the VPN if that’s your goal.
Check for IP leaks using online tools from a connected device to confirm traffic is exiting via the VPN IP.

Maintenance and updates Does nordvpn track your browser history the real truth revealed
