Prerequisites and Planning
Before you dive in, map out your OpenVPN setup so you don’t get stuck halfway. You’ll typically need:
- A MikroTik router with RouterOS 6.x or newer
- A remote OpenVPN server you control could be a home server, a VPS, or a company VPN
- Server address IP or domain, port, and protocol UDP is common, TCP can be more stable over unreliable networks
- Certificates and keys: CA certificate, client certificate, and client key or a combined PEM
- An idea of your network layout: what devices will use the VPN, and which networks should route through it
Why MikroTik OpenVPN?
- It’s relatively straightforward and widely supported
- Gives you full control over routing and access rules

Certificate setup CA, server, and client
If you’re using a full OpenVPN server certificate setup, you’ll need:
- CA certificate ca.crt
- Client certificate client.crt and client key client.key
- Optional: TLS-auth key ta.key for an extra layer of HMAC authentication
Option A: PEM bundle simpler for beginners Does Mullvad VPN Have Servers in India? A Clear Guide to Mullvad, India, and Alternatives
- Combine ca.crt, client.crt, and client.key into a single client.pem file if your server supports it.
- This reduces the number of files you manage on the MikroTik.
Option B: Separate files classic OpenVPN
- Keep ca.crt, client.crt, and client.key as separate files on MikroTik for clarity.
What to prepare on the OpenVPN server side
- Server address and port
- The exact DNS/route rules you want to push to clients
- Whether to use TLS-auth ta.key and the shared secret
- Cipher and MAC settings that are compatible with MikroTik AES-256-CBC with SHA256 is common
MikroTik OpenVPN Client Configuration
We’ll walk through a practical, copy-paste friendly setup. Adjust values to your environment.
-
Exchange rate of security and compatibility
- Use tun mode for OpenVPN to get a proper layer-3 VPN

- Enable compression only if your server uses it; otherwise, leave off to prevent vulnerabilities
-
Step 1: Create the OpenVPN client interface Total vpn on linux your guide to manual setup and best practices: A Practical, SEO-Driven Tutorial for Linux Users
- Name: openvpn-out
- Protocol: udp or tcp
- Server: your-openvpn-server.example.com
- Port: 1194 or your server’s port
- User/pass: Use certificate-based auth, not username/password when possible
-
Step 2: Import certificates and keys
- If using separate files:
- ca.pem: CA certificate
- cert.pem: Client certificate
- key.pem: Client private key
- If using a single PEM bundle:
- client.pem: combined certificate and key and possibly the CA
- In MikroTik, you’ll import these under System > Certificates or import the PEM file via Files, then reference them in the VPN profile
- If using separate files:
-
Step 3: Create the VPN profile
- Name: openvpn-profile
- Protocol: 2 OpenVPN
- Client Certificate: client certificate
- CA Certificate: CA certificate
- TLS Key ta.key: optional if server uses tls-auth
- Crypto: cipher AES-256-CBC, auth SHA256
- Verify server certificate optional
- Server address: your-openvpn-server.example.com
- Port: 1194
- Encrypt data channel: yes
-
Step 4: Set up the OpenVPN client interface with the profile
- Interface: openvpn-out
- Mode: ip
- Local port: optional; usually left as default
- Tunnel IP: let MikroTik assign via server-side config or set explicit IP, e.g., 10.8.0.2
-
Step 5: Add routing rules
- Route all traffic through the VPN: add a default route via the OpenVPN interface
- Route only specific subnets if you don’t want to send all traffic through VPN
-
Step 6: DNS configuration Does Proton VPN Have Dedicated IP Addresses: Everything You Need to Know
- Decide if you want DNS queries to go through VPN
- Add a DNS server via OpenVPN’s pushed DNS, or configure a secure DNS over VPN
-
Step 7: Save and enable
- Apply all changes
- Start the OpenVPN client and watch logs for connection status
-
Step 8: Verify the connection
- Check the interface status
- Ping a remote resource accessible only through VPN
- Check IP address from a connected client to confirm the public IP matches the VPN endpoint
Firewall and NAT Rules
- Allow OpenVPN traffic on the chosen port UDP/TCP
- Permit traffic from the VPN tunnel to your local networks if you want access to LAN devices
- Add NAT rules if you want VPN clients to access the internet through the VPN tunnel
- Example rule:
- Chain: src-nat
- Src. Address: 10.8.0.0/24 your VPN network
- Out. Interface: openvpn-out
- Action: masquerade
Routing and DNS Considerations
- Decide if all traffic should go through VPN or only traffic to specific subnets
- If you’re routing to a remote LAN, ensure proper static routes are set on MikroTik
- Ensure DNS leaks don’t occur; configure DNS through VPN or set DNS override on clients
Testing and Validation How to Turn Off Auto Renewal on ExpressVPN a Step by Step Guide: Easy, Precise, and Updated for 2026
