What you’ll need prerequisites
- MikroTik router with RouterOS recent version recommended
- Access to Winbox or WebFig preferred for ease
- OpenVPN client configuration from your VPN provider usually a .ovpn file
- Certificates and keys if provided separately ca.crt, client.crt, client.key
- A stable local network to test against LAN IP, gateway
- Basic networking knowledge IP addressing, routes, DNS basics
Step-by-step setup guide
- Prepare your MikroTik
- Update RouterOS to a recent stable version to ensure OpenVPN support is robust.
- Make a backup of your current configuration before making changes.
- Note your current LAN subnet and the WAN interface name.
- Transfer OpenVPN client files to MikroTik
- If you have a .ovpn file, you’ll extract the server address, port, protocol UDP/TCP, and the certificate/key data if needed.
- Some VPN providers give separate certificate files; you’ll upload them to MikroTik via Files in Winbox/WebFig or through a script.
- Create a new OpenVPN client interface
- Go to Interfaces > Add New > PPTP/L2TP/OpenVPN client depending on RouterOS version, you’ll choose OpenVPN client.
- Fill in the required fields:
- Name: openvpn-client
- Mode: ip-tunnel or ip
- Protocol: UDP or TCP as specified by your provider
- Port: 1194 or as given
- Server: VPN server address from .ovpn
- User: VPN username if your provider uses username/password
- Password: VPN password if applicable
- Certificates: select ca.crt, client.crt, client.key if your provider uses them; otherwise, supply credentials
- Profile: default or a custom profile you create for DNS and MTU
- Enable the interface after creation
- Configure IP addressing and routing
- Set an IP address for the VPN interface if needed some setups use a virtual interface with no fixed IP, others do.
- Add a route to direct all or certain traffic through the VPN:
- For all traffic: add a default route via the OpenVPN interface
- For selective traffic: add specific routes e.g., only traffic to certain subnets
- Example: add a route dst-address=0.0.0.0/0 gateway=openvpn-client
- Ensure DNS is routed through VPN or configured to use a trusted DNS resolver
- Set dns-name-servers to a provider’s DNS or a privacy-focused resolver e.g., 1.1.1.1 or 9.9.9.9
- If needed, create a rule to use VPN as the primary DNS, with a fallback to your ISP DNS
- Authentication and certificates if applicable
- If your provider requires cert-based auth, upload the CA certificate and client certificate/keys in the OpenVPN client config.
- If your provider uses TLS-auth or TLS-crypt, copy the ta.key file into the appropriate place and reference it in the OpenVPN client configuration.
- Firewall rules and NAT
- Ensure OpenVPN traffic is allowed through the firewall:
- Allow UDP/TCP 1194 or your configured port inbound/outbound on the WAN interface as needed
- If you’re routing all traffic through VPN, configure NAT on the VPN interface if you want devices on the LAN to share a single VPN-exposed public IP
- Example: /ip firewall nat add chain=srcnat out-interface=openvpn-client action=masq
- Consider split-tunneling if you don’t want all devices to go through VPN:
- Add firewall or routing rules to only send specific subnets through the OpenVPN interface
- DNS considerations and leak protection
- To avoid DNS leaks, force DNS requests to go through the VPN tunnel:
- Use a VPN-provided DNS or a secure resolver
- Implement DNS over TLS/HTTPS if supported by your client
- Test for DNS leaks with online tools after connection is established
- Start and verify the connection
- Enable the OpenVPN client interface
- Check the status:
- Look for “status” or “connected” in the VPN client interface
- Verify that the VPN interface has an IP assigned and that traffic is routing through it
- Test connectivity:
- From a device on the LAN, check your public IP on a site like whatismyipaddress.com to confirm it changes to the VPN’s IP
- Ping a resource through the VPN to verify reachability
- Troubleshooting common issues
- Connection fails: re-check server address, port, protocol, and credentials
- Certificates not found: ensure file paths and names match the OpenVPN configuration
- DNS leaks: verify DNS settings and ensure DNS requests route through VPN
- MTU issues: reduce MTU if you see fragmented packets or VPN dropouts
- Double NAT issues: ensure your MikroTik is directly connected to the modem in bridge mode if possible
- Performance and stability tips
- Use a wired connection for best VPN performance and minimal latency
- Prefer UDP over TCP for OpenVPN for lower overhead, unless your provider specifies otherwise
- Keep your MikroTik’s CPU load in check; heavy VPN usage can tax modest routers
- Schedule regular reboots or maintain uptime monitoring to catch silent VPN drops
Advanced tips
- Split tunneling setup
- Identify the subnets that should or should not go through VPN
- Create routing rules to send only those subnets via openvpn-client
- Example: add route dst-address=203.0.113.0/24 gateway=openvpn-client
- Kill switch for LAN devices
- Disable internet if VPN goes down by monitoring the VPN interface status and toggling the default route
- Redundancy and failover
- If you have multiple VPN providers, you can set up a primary/secondary VPN and switch over automatically if one fails
Security best practices
- Keep RouterOS updated to the latest stable version
- Use strong, unique credentials for VPN access
- Disable unused services on the MikroTik device
- Regularly back up configurations
- Consider enabling firewall rules to block unexpected inbound traffic

Frequently Asked Questions
Can I use OpenVPN on MikroTik RouterOS?
Yes, MikroTik supports OpenVPN client configuration on compatible RouterOS versions. You’ll need the OpenVPN client configuration and possibly certificates from your VPN provider.
Do I need certificates for OpenVPN on MikroTik?
Not always. It depends on your provider. Some use username/password with TLS, others require certificate-based authentication, including ca.crt, client.crt, and client.key. How to Turn Off Auto Renewal on ExpressVPN a Step by Step Guide and More Tips
Should I use UDP or TCP for OpenVPN?
UDP is generally faster and preferred for VPN traffic due to lower overhead and latency. TCP can be more reliable on lossy networks but may add extra overhead.
How do I route all traffic through the VPN?
Set a default route through the OpenVPN interface 0.0.0.0/0 via openvpn-client. Ensure DNS requests also route through the VPN or use a VPN-provided DNS.
How can I test my VPN connection from a LAN device?
From any connected device, visit a site like whatismyipaddress.com to confirm your public IP matches the VPN, and test connectivity to a resource reachable only via VPN.
What if the VPN drops?
Implement a simple kill switch by ensuring the default route goes through the VPN and monitor the VPN interface for stability. You can script a failover to another interface if needed.
How do I enable DNS through the VPN?
Configure the DNS server to be a VPN-provided DNS or a privacy-friendly resolver, and ensure DNS requests are routed through the VPN tunnel. Does nordvpn track your browser history the real truth revealed: Can NordVPN See Your History? What You Need to Know
Can I split traffic to only some devices go through VPN?
Yes, with careful routing. Use firewall and routing rules to designate which subnets or devices use the OpenVPN client for outbound traffic.
How often should I update RouterOS?
Keep RouterOS updated to the latest stable version to ensure you have the latest OpenVPN improvements and security fixes.
Is there a risk using OpenVPN on Mikrotik for gaming or streaming?
VPNs can add latency; UDP OpenVPN often helps. If you experience lag, try a VPN server closer to your location or adjust MTU settings and routing to minimize hops.
