A stable internet connection

Why OpenVPN on MikroTik

Strong encryption and broad compatibility
Works well on consumer-grade hardware
Easy to manage via RouterOS, with VPN client and firewall rules integrated

Before you start: gather essential files

CA certificate ca.crt
Client certificate client.crt and client key client.key, if using TLS authentication
Optional: TLS-auth key ta.key if your server requires it
OpenVPN server address and port for example: vpn.example.com:1194
VPN protocol UDP is common; TCP can be necessary for some networks

High-level overview of the setup

Create a new OpenVPN client interface on MikroTik
Add server and authentication details
Import certificates or apply TLS keys
Configure IP addressing and routing to send desired traffic through the VPN
Set up firewall rules to allow VPN traffic and protect the network
Test the connection and monitor logs for issues

Step-by-step setup

Access your MikroTik router

Open WinBox or WebFig
Log in with admin credentials
Ensure you’re on a recent RouterOS version 6.x or 7.x, depending on your device

Create the OpenVPN client server entry

Go to PPP > Interfaces
Click the “plus” + and choose OpenVPN Client or VPN Client in some versions
Name the interface: e.g., OpenVPN-Client
Remote Address/Tunnel network: leave default or set if your server requires a specific tunnel IP
Don’t enable yet; we’ll configure after authentication setup

Configure the OpenVPN client settings

Server: vpn.example.com or IP
Port: 1194 or your server’s port
Protocol: UDP or TCP if required by server
Username/Password: leave blank if you’re using certificate-based auth; if your server uses a username/password combo, enter them here
Certificate: select the client certificate if you’re using TLS authentication
TLS Key: if your server uses TLS-auth or a pre-shared key, import and select it
Verify server certificate: enable if you have a CA chain optional depending on your server
Cipher/Hash: leave as default unless your server requires something specific
Compression: disable unless your server requires it

Import and configure certificates if using TLS

Go to System > Certificates if you need to add or manage locally
Import the CA certificate ca.crt if required by your server
Import the client certificate client.crt and key client.key
If using a static TLS-auth key ta.key, import as a TLS key and reference it in the OpenVPN client settings

Set up the VPN interface with certificates and keys

In the OpenVPN Client settings, for the certificate, choose your client certificate
For TLS authentication if used, add the ta.key in the appropriate field TLS Auth Key

Enable and connect

Apply the changes
Toggle the OpenVPN Client interface to enable
You should see status as connected if everything is correct
If not, move on to troubleshooting

Configure routing for VPN traffic

Decide which devices or networks should use the VPN
To route all traffic through VPN:
- Add a route to 0.0.0.0/0 via the OpenVPN-Client interface
- Ensure your default route switches to use the VPN for outbound traffic
To route only specific subnets through VPN:
- Add static routes for those subnets via the VPN interface
If you’re using MikroTik as a gateway for LAN devices, enable the VPN as the default gateway for outbound traffic or configure policy-based routing as needed

DNS considerations

Decide whether to use VPN-provided DNS or your local DNS
If the VPN provides DNS, ensure your DNS requests go through the VPN when connected
If you want Local DNS when VPN is up, you might set:
- DNS servers to your VPN DNS or a fallback offline DNS
- Add a routing rule to skip VPN-based DNS leakage for non-VPN clients

Firewall and NAT rules

Create firewall rules to allow VPN traffic
If you route all traffic through VPN, ensure LAN to VPN interface traffic is allowed
If you’re using NAT for LAN devices, add a masquerade rule on the VPN interface for outbound traffic
Example: ip firewall nat rule chain=srcnat out-interface=OpenVPN-Client action=masquerade

Verify the VPN connection

Check the OpenVPN client interface status for connected state
Use tools like ping or traceroute to the VPN server IP
Verify the public IP from a remote source to confirm traffic is going through VPN
Check MikroTik log for OpenVPN-related messages: Log > /log print where you’ll see messages about TLS handshake, certificate validation, or errors

Common pitfalls and quick fixes

Certificate mismatch: Double-check that the CA, client cert, and key pair match the server’s configuration
TLS-auth key mismatch: Ensure ta.key is correctly referenced on both client and server, and that the file contents are correct
Port or protocol mismatch: Verify port and protocol match the server’s OpenVPN config
DNS leaks: If DNS queries bypass VPN, consider using VPN-provided DNS or a secure, private DNS
Firewall blocking: Ensure the MikroTik firewall allows OpenVPN traffic and the VPN interface traffic
Device bandwidth constraints: Some MikroTik devices may see limited performance on high-speed VPN connections; adjust MTU if needed
MTU issues: If you see odd disconnects or packet loss, try a smaller MTU on the OpenVPN interface e.g., 1400

Advanced tips for power users

Use user authentication for OpenVPN if your server supports it; it adds a layer of security
Implement split tunneling: route only specific IPs or subnets through VPN, leaving rest of traffic on the local network
Enable keepalive or ping-timer-restart in the OpenVPN settings to maintain a stable connection
Schedule automatic reconnects or monitor the VPN status via scripts and alerts
Log more details for debugging: increase the OpenVPN client log level if you have the option

Sample configuration snippets conceptual

OpenVPN Client interface creation:
- Interface: OpenVPN-Client
- Server: vpn.example.com
- Port: 1194
- Protocol: UDP
- Certificate: client.crt
- TLS Auth Key: ta.key
Routing all traffic through VPN:
- /ip route add dst-address=0.0.0.0/0 gateway=OpenVPN-Client
- /ip firewall nat add chain=srcnat out-interface=OpenVPN-Client action=masquerade
DNS through VPN example concept:
- /ip dns set servers=10.8.0.1 allow-remote-requests=yes
- Ensure DNS requests from VPN clients resolve correctly

Maintenance and monitoring

Regularly check OpenVPN client status in RouterOS

Frequently Asked Questions

How do I know if OpenVPN client is connected on MikroTik?

You can check the OpenVPN client interface status under PPP > Interfaces. It should show as connected with a tunnel IP assigned. You can also review /log for handshake messages and test connectivity by pinging the VPN server or a resource only reachable via VPN.

Can I use OpenVPN with a MikroTik router with RouterOS v6?

Yes, MikroTik supports OpenVPN as a client in RouterOS v6 and later. If you’re on a very old device, you may need to upgrade or use a different VPN method.

Should I route all traffic through the VPN or only specific subnets?

Both approaches work; route all traffic provides full privacy but may add latency. Split tunneling lets you keep local internet access for non-VPN devices while forwarding only critical traffic via VPN.

What certificates do I need for OpenVPN on MikroTik?

Typically you’ll need:

CA certificate ca.crt
Client certificate client.crt
Client key client.key
Optional: TLS-auth key ta.key if your server uses it

How do I fix “TLS handshake” errors?

Common causes: certificate mismatch, wrong server address/port, time skew on the router, or blocked ports. Double-check server details, certificate validity, and ensure the firewall isn’t blocking OpenVPN traffic. Sling tv not working with a vpn heres how to fix it 2026

What is TLS-auth and do I need it?

TLS-auth adds an extra HMAC signature to TLS control channels, improving security. If your server requires it, you’ll need to import ta.key and reference it on both client and server.

How can I test that traffic goes through the VPN?

Run a test from a client behind the MikroTik or use an online IP check to confirm the public IP is that of the VPN exit node. Also test access to resources only available via the VPN.

Can I use OpenVPN with multiple VPN providers on the same MikroTik?

You can configure multiple OpenVPN clients, but MikroTik’s router resources and routing tables can get complex. It’s easier to run only one VPN client per MikroTik device for stability.

How do I enable automatic reconnection if the VPN drops?

In the OpenVPN client settings, enable keepalive or similar settings provided by RouterOS, and consider a script that periodically checks the connection and reinitializes the VPN client if it’s down.

What if my VPN provider requires a username and password?

If your server supports certificate-based auth plus username/password, input the credentials in the OpenVPN client settings where applicable. Some servers require you to provide credentials via a separate auth file or inline in the client configuration.

Step-by-step outline

Prerequisites and planning

Confirm your MikroTik model supports OpenVPN client mode RouterOS version 6.x/7.x generally supports OpenVPN client with appropriate package.
Decide whether you’ll use TLS-based OpenVPN with certificates or a simpler TLS-auth/pre-shared key setup.
Gather VPN server details: server address, port, protocol UDP/TCP, CA certificate, client certificate, client key, and any TLS auth key.
Plan your internal IP subnet and routing so traffic from devices behind the MikroTik uses the VPN tunnel when needed.

Prepare your VPN server and certificates

If your VPN provider or server uses certificates, you’ll need:
- CA certificate ca.crt
- Client certificate client.crt
- Client key client.key
If you’re using a provider that offers a config file, extract the necessary components CA, cert, key. If you’re using a pre-shared key, you’ll skip certs and use tls-auth with a static key.
Store these files securely and ensure MikroTik can access them via files area or through the configuration input.

Create or import certificates on MikroTik

In MikroTik RouterOS, go to System > Certificates.
Import CA certificate if you have it as a .crt file.
Import the client certificate and client key if using certificate-based authentication.
If you’re using a CA-signed chain, verify the certificate status and ensure it’s not expired.

Configure OpenVPN client on MikroTik

Open the RouterOS terminal or Winbox/WebFig.
Add a new OpenVPN client interface with the required settings:
- Name: vpn-out
- Connect to: your.vpn.server.ip
- Port: 1194 or the port your server uses
- User: if required by server
- Password: if required by server
- Mode: ip
- Protocol: udp or tcp per server
- Dev: tun
- TLS-crypt or tls-auth secret if your server uses tls-auth, enable and point to the key
- Verify server certificate optional using the CA you imported
- Certificate: select the client certificate if using cert-based auth
- TLS key and CA: reference the imported certs
- Use TLS: yes
Example commands adjust names to your setup:
- /interface ovpn-client add name=vpn-out connect-to=YOUR_VPN_SERVER_IP port=1194 mode=ip tls-cert-profile=server-fqdn user=USER password=PASSWORD add-default-route-distance=1 use-peer-dns=yes profile=default auth=sha256 cipher=aes-256-cbc
Note: MikroTik OpenVPN uses a specific set of cipher and auth options; if your server requires different options, adjust accordingly.

Set up routing and DNS

After the VPN client is up, create a route to direct traffic through the VPN:
- /ip route add dst-address=0.0.0.0/0 gateway=vpn-out
Ensure DNS queries from clients resolve via the VPN. You can set:
- /ip dns set servers=YOUR_VPN_DNS
- Or push DNS via DHCP for devices on the LAN to use VPN DNS.
If you want split tunneling, don’t set the default route via VPN for all traffic. Instead, add specific routes for the VPN-only networks.

Firewall rules and NAT

Allow OpenVPN traffic in the firewall:
- /ip firewall filter add chain=input protocol=tcp dst-port=1194 action=accept comment=”OpenVPN TCP 1194″
- /ip firewall filter add chain=input protocol=udp dst-port=1194 action=accept comment=”OpenVPN UDP 1194″
If you’re using NAT for VPN clients, ensure the VPN interface is allowed to masquerade:
- /ip firewall nat add chain=srcnat out-interface=vpn-out action=masquerade
For VPN-only devices, you may want to implement firewall rules to restrict local LAN access unless through VPN.

Test the connection

Check the status of the OpenVPN client:
- /interface ovpn-client print
Look for established connection and a successful tunnel:
- The CLI will show “connected” and “ip-address” assigned on the vpn-out interface.
Test from inside your LAN:
- Ping an IP address reachable only via VPN, or check your public IP from a device behind the MikroTik using an online tool to verify it shows your VPN exit node.

Common issues and fixes

If the VPN doesn’t connect, check:
- Certificates: valid, not expired, correctly referenced
- Server address and port: reachable from MikroTik no firewall blocking
- TLS-auth or tls-crypt: correct key and settings
- Cipher and TLS version compatibility with the server
If DNS leaks occur, force DNS resolution through VPN by pointing LAN DNS to VPN’s DNS server or use a DNS firewall.
If slow speeds appear, consider changing the cipher, enabling compression only if server supports it, or upgrading RouterOS if you’re on an older version.

Advanced tips

Route-only specific subnets through VPN split tunneling:
- Add static routes for specific destinations via VPN gateway and leave default route out of VPN.
Use VPN firewall rules to drop traffic that attempts to bypass VPN:
- Create rules to drop traffic from LAN that doesn’t go through VPN for protected subnets.
Monitoring and logging:
- Enable logging for OpenVPN events to catch dropped connections or certificate issues.
Redundancy:
- If you have multiple VPN servers, you can script a failover by monitoring the VPN interface status and switching to a backup server.

Performance and security considerations

Keep RouterOS updated to the latest stable version to ensure OpenVPN performance improvements and security patches.
Use strong ciphers AES-256-CBC or higher and SHA-256 or stronger for TLS.
Consider enabling VPN bonding or multiple VPN tunnels if you need higher throughput or reliability, depending on your hardware.
Regularly rotate client certificates and keys if you’re managing your own VPN infrastructure.

Quick wins to boost VPN experience

Enable DNS over VPN by pushing VPN DNS settings to clients to prevent leaks.
Use a dedicated VLAN for VPN traffic to isolate it from the main LAN.
Schedule occasional reconnects or health checks to maintain a stable tunnel.
Back up your MikroTik configuration after you confirm VPN is working.
