Prerequisites
Before you start, make sure you have:

A MikroTik router with RouterOS that supports OpenVPN client mode most recent devices do
Administrative access to the MikroTik router WinBox or WebFig or CLI
A valid OpenVPN .ovpn profile or the key/cert pair provided by your VPN service
A stable internet connection from your local network to the MikroTik router
Basic understanding of firewall rules and NAT on RouterOS

What you’ll need

OpenVPN server address or VPN service hostname
OpenVPN protocol compatible with MikroTik UDP is common; TCP is available but slower
VPN credentials username/password or certificate-based, depending on your provider
The OpenVPN client certificate and key if your provider uses cert-based auth
Certificate Authority CA certificate content or a CA file from your provider
Optional: DNS on the VPN to avoid leaking DNS to your ISP

Step-by-step guide
Step 1: Prepare your OpenVPN configuration

If you have an .ovpn profile, open it and extract:
- remote server address and port
- proto udp or tcp
- dev tun or tap, typically tun
- ca CA certificate content
- cert client certificate content and key client private key content, if certificate-based
- auth-user-pass if using username/password
If your provider gives separate certs, combine them into the MikroTik’s OpenVPN client config later.

Step 2: Access MikroTik RouterOS

Use WinBox or WebFig to log in as admin.
For CLI, connect via SSH or the terminal in WebFig.

Step 3: Create the OpenVPN client interface How to Turn Off Auto Renewal on ExpressVPN A Step by Step Guide

In RouterOS, OpenVPN client is configured under /interface ovpn-client
Example adjust to your data:
- add name=ovpn-out1 connect-to=vpn.example.com port=1194 mode=ip-optionresp disable-dns=no user=username password=password profile=default

Notes:

If you have certificate-based authentication, you’ll need to import the CA, client cert, and key into /certificate and then reference them in the ovpn-client settings.

Step 4: Import certificates and keys if required

Import CA:
- /certificate import file-name=ca.crt
Import client certificate:
- /certificate import file-name=client.crt
Import client key:
- /certificate import file-name=client.key
Make sure the certificates are issued properly and trusted by the device.

Step 5: Configure OpenVPN client with certificate and keys

If you’re using cert-based auth, you’ll reference the certs in the ovpn-client:
- set -cert=cert-client
- set -key=key-client
- or specify the appropriate certificate/identity in the ovpn-client config
If you’re using username/password:
- set ovpn-out1 user=username password=password

Step 6: Set remote and protocol

Ensure the connect-to address matches the VPN server hostname and the port matches the provider’s spec
Set mode to ip-option or default depending on your RouterOS version
Choose protocol udp or tcp according to the server you’re connecting to

If your VPN provides a DNS server, enable dns and set the DNS servers under /ip dns
To avoid DNS leaks, set the VPN to use VPN-provided DNS by setting the VPN to override DNS or by configuring DNS in the client or by routing DNS queries through the VPN

Step 8: IP routing and firewall

Add a route to ensure VPN traffic goes through the OpenVPN interface
- /ip route add dst-address=0.0.0.0/0 gateway=ovpn-out1
Add NAT rules if you’re sharing VPN across a LAN:
- /ip firewall nat add chain=srcnat out-interface=ovpn-out1 action=masquerade
Important: If you only want certain traffic to go through VPN split-tunneling, adjust the routing rules accordingly.

Step 9: Start the OpenVPN client

In WinBox/WebFig: click the interface ovpn-out1 and enable it
In CLI:
- /interface ovpn-client enable ovpn-out1
Check status:
- /interface ovpn-client print
- You should see connected status with bytes sent/received

Step 10: Verify the VPN connection

Check external IP to confirm VPN is in use:
- curl ifconfig.me
Check routing table:
- /ip route print where gateway=ovpn-out1
Check DNS resolution to ensure it’s using VPN DNS if configured

Verifying the VPN connection with practical checks

Test a site that may be blocked in your region to confirm you’re using the VPN exit node
Ping a known host through VPN to test latency
Use traceroute to see the path to a remote server
Confirm that your home network’s public IP changes when the VPN is connected

Common issues and fixes Does nordvpn give out your information the truth about privacy

OpenVPN not starting:
- Check logs for certificate errors or misconfigured server address
- Ensure CA, cert, and key are correctly imported and referenced
DNS leaks:
- Ensure the VPN DNS server is used by the router and DNS requests are routed through VPN
Connection drops:
- Check for IP address conflicts or firewall rules blocking VPN traffic
Split-tunnel issues:
- If you configured split tunneling, ensure the routes for non-VPN traffic are correct and not overriding VPN routes
Performance slowdowns:
- Change to UDP if you’re using TCP; adjust MTU if you see fragmentation
- Consider changing VPN server to a closer location for lower latency

Performance tips

MTU tuning: Start with 1500 and reduce in 50-byte steps if you see fragmentation; test until stability improves
Use UDP whenever possible for better throughput
Disable IPv6 on VPN interfaces if your VPN provider doesn’t support IPv6 well to avoid leaks
Enable compression only if your provider supports it and you’re not seeing CPU load issues note: compression can increase CPU usage and may not improve speeds on modern hardware
Regularly update RouterOS to ensure OpenVPN client compatibility and security patches
Consider a dedicated VPN policy for your critical devices to ensure consistent routing

Security considerations

Use strong credentials and avoid plain usernames/passwords if possible
Prefer certificate-based authentication when available
Keep the CA and certificates secure; rotate keys periodically
Use a trusted VPN service with a no-logs policy if privacy is the goal
Regularly review firewall rules to block any unintended traffic leaks
Monitor VPN status and logs for unusual activity

Alternative VPN options on MikroTik

WireGuard: If your Mikrotik device supports WireGuard RouterOS v17+, it often provides better performance and simpler configuration than OpenVPN
PPTP/L2TP: Consider only if required for compatibility; these are less secure and generally not recommended
SSTP: Useful in some Windows-centric environments but not as widely supported on MikroTik as OpenVPN or WireGuard

FAQ

Why use OpenVPN on MikroTik instead of WireGuard?
OpenVPN has broad compatibility and works well with many providers; WireGuard offers better performance but may require more manual setup with some providers. Both are viable; your choice depends on your needs and hardware support.
Can I run multiple OpenVPN clients on a single MikroTik router?
Yes, you can run multiple ovpn-client interfaces and route different traffic or networks through different VPN tunnels, but it increases configuration complexity.
How do I force all traffic through the VPN?
Create a default route via the OpenVPN interface and disable the default internet route, or set up appropriate policy-based routing to push all traffic through the VPN.
What devices should connect through VPN?
Generally, devices that need privacy, access to a remote network, or geo-specific content. You can also route all traffic from your LAN through VPN.
Why is my VPN IP not changing?
Check for DNS leaks and ensure the OpenVPN client is the default route for outbound traffic. Verify that the VPN server is actively routing traffic.
How often should I rotate VPN credentials?
Rotate certificates and credentials periodically, and immediately if you suspect a compromise.
Can I use my VPN with NAT?
Yes, NAT is common when sharing VPN across a LAN; ensure your masquerade rule for the VPN interface is in place.
What if the VPN disconnects?
Enable a monitor for the OpenVPN client; configure a script to reconnect automatically if the VPN drops.
Do I need firewall rules for the VPN?
Yes, to prevent leaks and to control what traffic is allowed to ride the VPN tunnel.
How can I test my VPN speed?
Use speed tests while connected via VPN and compare with baseline speeds when disconnected to gauge performance impact.
