- Client certificates and keys if your server uses TLS authentication or PKI-based authentication.
- A computer to generate or obtain client keys/certs if you’re setting up your own PKI.
- Basic familiarity with Winbox/WebFig or SSH for MikroTik management.
Important note on OpenVPN modes
- OpenVPN over TCP is typically more reliable for VPN passthrough, but may be slightly slower.
- OpenVPN over UDP can be faster but is slightly more sensitive to network blocking.
- MikroTik supports OpenVPN client mode but not every feature is identical to a full OpenVPN client on Linux. Plan accordingly.
High-level overview of the steps
- Prepare the OpenVPN server credentials and client certificates.
- Create a PPP profile and interface for the VPN tunnel.
- Import or create CA certificate, client certificate, and private key on the MikroTik.
- Configure the OpenVPN client with the server, port, and authentication method.
- Set up routing and firewall rules to allow VPN traffic and to route desired subnets through the VPN.
- Test the VPN connection and monitor for any drops or leaks.
- Optional: add auto-reconnect and DNS considerations.
- Optional: harden security with additional firewall customization and MTU tuning.
Detailed setup guide
A. Prepare certificates and server details
- If your OpenVPN server uses TLS authentication TLS-Auth, you’ll need a static key file ta.key in addition to CA, client cert, and client key.
- If using PKI, ensure you have:
- CA certificate ca.crt
- Client certificate client.crt
- Client private key client.key
- Your server address and port e.g., vpn.yourdomain.com:1194
- Protocol tcp-client or udp-client depends on server config
B. Import certificates on MikroTik Does Mullvad VPN Work on Firestick Your Step by Step Installation Guide
- Use either Winbox or WebFig to access your MikroTik router.
- Go to Files to upload ca.crt, client.crt, client.key, and ta.key if used.
- Load certificates:
- System > Certificates > Import
- Import CA certificate as ca
- Import client certificate as certificate with the corresponding private key
- If using TLS-Auth, import ta.key as a TLS-auth key mode TLS-auth or tls-auth depending on RouterOS version
C. Create the OpenVPN client interface
- Go to PPP > Interface > Add > OVPN Client openvpn-client
- Common fields to fill:
- Name: ovpn-out
- Connect to: vpn.yourserver.com server address
- Port: 1194 or your server port
- Mode: ip
- User: not used for OpenVPN use Certificates
- Password: not used
- Profile: default-encryption or a custom profile if you’re setting specific ciphers
- Certificate: choose the client certificate
- Key: choose the client private key if required
- CA certificate: choose the CA certificate
- TLS-auth Key: choose ta.key if used
- TLS: enabled
- Verify server certificate: enabled for extra security
- TLS Ciphers: choose a strong cipher supported by both sides e.g., TLS1.2 or higher
- Server CA: optional if not auto-detected
- Advanced:
- Use Peer DNS: true if you want the VPN to provide DNS
- Add Default Route: yes to route all traffic through VPN
- MTU: 1500 or adjusted if needed
- Encryption: select AES-256-CBC or as per server
- TLS Version: 1.2 or higher
- Save and apply
D. Firewall and NAT considerations
- Ensure you allow OpenVPN traffic through the WAN interface if needed.
- Add a firewall rule to allow the VPN to initiate:
- /ip firewall filter add chain=input action=accept protocol=tcp dst-port=1194 comment=”OpenVPN inbound” adjust port
- NAT: If you want clients on the VPN to access the internet via VPN, you will typically set:
- /ip firewall nat add chain=srcnat src-address=10.8.0.0/24 to-addresses=0.0.0.0 out-interface=ovpn-out
- Or simply set the default route through ovpn-out and ensure masquerade on the WAN interface for non-VPN traffic if needed
- Enable masquerade for VPN clients:
- /ip firewall nat add chain=srcnat out-interface=ether1 action=masquerade
E. Routing considerations
- If you’re only sending specific subnets through the VPN, don’t enable Add Default Route; instead, add static routes for the VPN subnet through the ovpn-out interface.
- If you want all traffic to go through VPN, enable Add Default Route in the OpenVPN client settings and set a higher distance for the LAN routes to prefer VPN.
F. DNS considerations
- If your VPN server provides DNS via the VPN, enable Use DNS from VPN usually in the OpenVPN client settings.
- If not, specify a public DNS server e.g., 1.1.1.1 or 8.8.8.8 for overall stability and privacy.
G. Auto-reconnect and keepalive Does nordvpn track your browser history the real truth revealed: What it means for your privacy, speed, and security
- In RouterOS, you can configure persistent connections by enabling:
- Reconnect Timeout: 30
- Reconnect Retry: 5
- Keepalive: yes
- You can adjust these values to match server stability and network conditions.
H. Verification steps
- Check the OpenVPN client status:
- /interface ovpn-client print
- Look for Status: connected and a valid IP address from the VPN server
- Verify routing:
- Run traceroute to a host on the VPN network or outside to confirm traffic flows through the VPN
- Test DNS leakage:
- From a connected device, go to whoer.net or dnsleaktest.com and confirm DNS queries are resolved via VPN or server-provided DNS
- Check for IP address changes with:
- curl ifconfig.me
- Monitor for disconnects and auto-reconnect events in the log:
- /log print where you look for ovpn-client
I. Common issues and quick fixes
- Issue: OpenVPN client does not start
- Fix: Confirm certificates are correctly loaded and that the server address and port are reachable from the MikroTik. Re-upload certificates if necessary.
- Issue: TLS handshake failure
- Fix: Ensure the correct TLS-auth key is in place and that the server’s TLS configuration matches cipher, TLS version. Confirm that CA, client certs are valid and not expired.
- Issue: VPN interface does not obtain an IP
- Fix: Check server-side VPN pool configuration; ensure the client certificate is allowed and that the server has a matching config. Check for IP pool conflicts on the client side.
- Issue: DNS leaks
- Fix: Force DNS to come from VPN or specify a private DNS resolver in the client settings.
Advanced tips for better reliability
- Split-tunnel vs full-tunnel:
- For split-tunnel, configure specific routes through ovpn-out and leave default route on LAN. For full-tunnel, enable Add Default Route and ensure DNS is handled by VPN.
- MTU tuning:
- If you encounter packet loss or MTU-related fragmentation, try lowering MTU to 1400 or 1420 to stabilize performance.
- DNS and security:
- Use a locked-down DNS provider and consider using DNS over TLS/HTTPS if supported by the router and server configuration.
- Monitoring:
- Set up periodic pings or a simple script to check VPN status and attempt reconnection if the tunnel goes down.
Comparison and best practices
- If you’re targeting stability on any network, opt for OpenVPN over UDP with TLS, keep the TLS version current, and enable TLS-auth where possible.
- For networks with strict firewall policies, TCP OpenVPN can help bypass filtering.
- Always back up existing MikroTik configurations before making big changes; a small mistake can take your network offline.
