Why use OpenVPN on Mikrotik?
OpenVPN is widely supported, flexible, and relatively easy to configure on many MikroTik devices. It gives you:
- A secure tunnel for all devices behind your router
- Remote access capabilities for traveling staff or devices
- Centralized management of VPN settings
If you’re using a MikroTik router with RouterOS that supports OpenVPN most modern models do, you’ll typically set up as a client to connect to an OpenVPN server managed by your VPN provider or an OpenVPN server you control.
Important note: Some MikroTik devices handle OpenVPN differently than PPTP or L2TP/IPsec. If you have an older RouterOS version or hardware limitations, you might prefer a different VPN protocol. Still, for many users, OpenVPN gives a great balance of security and compatibility.
Prerequisites and quick checks
Before you start, gather and verify these items:
- MikroTik router with RouterOS installed version 6.x or 7.x is common; ensure OpenVPN client support
- OpenVPN server address hostname or IP, port, protocol UDP is usually faster
- OpenVPN client certificate and key or a combined .ovpn file from your VPN provider/server
- VPN username and password if required by your server
- A computer to download certificates and copy config if needed
- Basic familiarity with MikroTik WinBox or WebFig WebFig is the web UI

- Confirm RouterOS supports OpenVPN client: go to System > Package List and ensure openvpn-client or openvpn is listed.
- Validate your internet connection on the Mikrotik: ping 8.8.8.8 from New Terminal.
- Gather your VPN credentials and config: certificate files CA, client cert, client key or an ovpn file.
- Decide on DNS handling: let VPN provider push DNS or set local DNS after the VPN connects.
Step-by-step guide to setting up OpenVPN client on MikroTik
This guide uses the common method of importing an OpenVPN profile or using certificate-based authentication. Adjust based on your server/provider specifics.
Step 1: Prepare certificates or ovpn file
- If you have an ovpn file, extract needed parts: ca.crt, client.crt, client.key, and possibly ta.key. Some providers give a combined file; in that case, you’ll paste the content into the Mikrotik’s fields.
- If you’re using certificate-based authentication, ensure you have:
- CA certificate ca.crt
- Client certificate client.crt
- Client private key client.key
- TLS auth key ta.key if your server requires it
Tip: Keep these files securely on your computer until you import into MikroTik.
Step 2: Create OpenVPN client interface
- Open WinBox or WebFig and log in to your MikroTik router.
- Go to Wireless or VPN section RouterOS 7x uses VPN > OpenVPN Client.
- Add a new OpenVPN Client:
- Name: openvpn-out
- Connect to:
- Port:
often 1194 - User:
leave blank for certificate-based - Password:
leave blank for certificate-based - Mode: tun 2 for most setups
- Protocol: udp
- Cipher: AES-256-CBC match your server
- TLS Auth: enable if your server uses ta.key
- TLS Key Usage: tls-auth or tls-crypt depending on your setup
- Verifying Server Certificate: require or none depends on server
- Add a CA certificate if needed: paste or import CA cert
- Client certificate: select client cert or paste if required
- Client key: select client key or paste if required
If you use an ovpn file, use the import feature:
- Files > OpenVPN > Import and select your .ovpn file. The router will populate fields automatically if the file includes necessary certs/keys.
Step 3: Transport and security settings
- Check the TLS mode and verify server certificate settings. If the server uses a private CA, you’ll need to add the CA certificate.
- Enable TLS for better security if your server requires it.
- For stability, set MTU to 1500 or auto and adjust if you observe packet loss.
Step 4: Set up routing and firewall rules
- Add a route to direct traffic through the VPN:
- Destination: 0.0.0.0/0
- Gateway: openvpn-out the VPN interface
- Ensure the VPN interface is brought up automatically on boot:
- System > Scheduler or System > Identity depending on your version to run a script that checks and re-establishes the VPN.
Firewall considerations:
- Create a firewall rule to allow VPN traffic:
- Chain: input
- Protocol: 17 UDP or 6 TCP depending on your server
- Dst. Port: 1194 default or your server port
- Action: accept
- Add a NAT rule if you want VPN clients to access the internet through the VPN:
- Chain: srcnat
- Src. Address: your LAN subnet
- Out. Interface: openvpn-out
- Action: masquerade
Step 5: DNS and split tunneling optional
- If your VPN provides DNS servers: add them via IP > DNS and set allow-remote-request to yes.
- If you want split tunneling only certain devices go through VPN, you’ll configure firewall rules and static routes for specific subnets.
Step 6: Test the connection
- Apply changes and watch the OpenVPN Client interface status.
- Check the IP from a connected client or use the Mikrotik terminal:
- /tool sniffer quick port=UDP:1194 on the VPN interface to see if packets flow
- /interface ovpn-client monitor openvpn-out
- Verify traffic route:
- Use traceroute from a client behind the MikroTik to a known external IP; you should see the VPN path.
Step 7: Troubleshooting common issues
- Connection refused or handshake fail:
- Re-check server address and port
- Confirm CA, cert, and key are correctly loaded
- Verify TLS auth settings match server
- No internet after VPN connects:
- Ensure default route uses the OpenVPN interface
- Check DNS settings to avoid leaks
- DNS leaks:
- Force DNS through VPN or set DNS to provider’s DNS inside VPN
- Certificate errors:
- Ensure CA certificate is correct and matches the server
- Confirm certificate validity dates
- Performance issues:
- Try UDP instead of TCP
- Reduce MTU if there’s fragmentation
Step 8: Security best practices
- Disable password login for SSH from the WAN if you’re exposed; use key-based authentication.
- Regularly update RouterOS to the latest stable release.
- Use strong certs and rotate keys periodically.
- Consider enabling firewall rules that limit VPN endpoints to trusted IPs if your setup allows it.
Step 9: Advanced tips for reliability
- Create a script to automatically restart OpenVPN if it goes down:
- Use a scheduler to periodically check /interface ovpn-client monitor status
- If status is down, issue /interface ovpn-client disable openvpn-out and enable again
- Enable connection keepalive or ping settings if your VPN supports them to maintain the tunnel during idle periods.
- Monitor VPN uptime and traffic with RouterOS tools or external monitoring e.g., Pingdom, PRTG to catch outages quickly.
Real-world testing and data
- In 2025, MikroTik users widely reported OpenVPN client configurations that work smoothly on the hAP ax3, CCR series, and Cloud Router Switch when you align certificates and server settings correctly.
- UDP generally yields lower latency and higher throughput for OpenVPN clients on MikroTik, especially for gaming and real-time apps.
- DNS leakage tends to be the most common issue for new setups; forcing DNS through VPN or using a providers’ DNS during VPN sessions helps mitigate this.

Frequently Asked Questions
How do I know if OpenVPN is supported on my MikroTik device?
Most newer MikroTik routers with RouterOS 6.x or 7.x support OpenVPN client. Check System > Package List in your router for openvpn-client or openvpn.
Should I use UDP or TCP for OpenVPN on MikroTik?
UDP is typically faster and preferred for VPN connections. TCP can be more stable on networks with restrictive firewalls but may introduce overhead.
Do I need certificates or can I use a .ovpn file directly?
Both approaches are valid. If you have a complete .ovpn file that includes certs/keys, you can import it directly. If you have separate certs/keys, you’ll configure them in the OpenVPN client settings.
How can I test that my traffic is going through the VPN?
- Check your public IP from a device behind the MikroTik before and after connecting to the VPN.
- Use traceroute to a known host to ensure the path goes through the VPN interface.
- Use DNS leak tests to confirm DNS requests are routed through the VPN.
What should I do if the VPN keeps disconnecting?
- Check for server-side restrictions or unstable server address.
- Ensure keepalive/ping settings are correct.
- Confirm certificates haven’t expired and re-import if needed.
- Look at system logs for disconnection reasons: /log once connected.
Can I run multiple VPN providers on one MikroTik?
You can configure multiple OpenVPN clients and set up routing policies, but it’s more complex and usually not needed for typical home setups. Use one default OpenVPN client and create specific routes if you need split VPNs.
How do I set up split tunneling with OpenVPN on MikroTik?
Configure static routes or firewall rules to bypass VPN for certain subnets or destinations. The VPN should still be up for the traffic you want to force through it. Does nordvpn track your browser history the real truth revealed
How do I import a complete .ovpn file on MikroTik?
In WinBox/WebFig, go to Files, upload the .ovpn file, then use the OpenVPN Client Import option, and the router will parse certificates, keys, and server settings automatically.
Is OpenVPN on MikroTik as secure as WireGuard?
OpenVPN is very secure and widely trusted, with broad compatibility. WireGuard is newer and often faster, but MikroTik supports it differently depending on RouterOS version and hardware. If you’re starting fresh, OpenVPN remains a solid, well-supported option.
Do I need a static IP on the OpenVPN server?
Not always; many VPN providers use dynamic addresses, but some corporate setups prefer static endpoints for reliability. Ensure you use the correct server address regardless.
How do I update OpenVPN server settings on the MikroTik after changes?
Edit the OpenVPN client settings, re-import the updated certificate if necessary, and re-establish the connection. Monitor the status to confirm the change took effect.
