What you’ll need before you start The Truth About What VPN Joe Rogan Uses And What You Should Consider
- A MikroTik router with RouterOS version that supports OpenVPN check your device model and RouterOS version
- Access to the MikroTik Winbox app or WebFig WebFig is the web interface
- An OpenVPN server you can connect to either your own server or a commercial VPN provider that supports OpenVPN with certificate-based authentication
- Certificates and keys: CA certificate, client certificate, client key, and possibly a TLS-auth key depending on your server configuration
- Basic networking basics: IP addressing, NAT, and route management
Step-by-step guide: Setting up OpenVPN client on MikroTik RouterOS
- Prepare certificates and configuration
- If you’re using a commercial VPN with certificate-based auth, obtain: CA certificate ca.crt, client certificate client.crt, client key client.key, and perhaps a ta.key for TLS-auth.
- If you’re running your own OpenVPN server, generate the necessary certificates and copy them to your MikroTik in .crt and .key formats where required.
- Decide on the OpenVPN mode: tun layer 3, routing vs tap layer 2, bridging. For most home setups, tun is recommended for performance and simplicity.
- Access your MikroTik router
- Open Winbox or WebFig and log in with admin credentials.
- Confirm your RouterOS version supports OpenVPN net.service.openvpn should be available.
- Import certificates into MikroTik
- Go to Files and upload ca.crt, client.crt, client.key and ta.key if needed.
- Then, in the terminal or through the GUI, import them, if necessary, and note their paths.
- Create and configure the OpenVPN client interface
- In RouterOS, create a new OpenVPN client interface:
- Name: openvpn-out
- Connect to:
- Port: 1194 default; adjust to your server
- Mode: ip tcp-client or ip client depending on server
- Protocol: udp or tcp match server
- User and Pass: not needed for certificate-based auth; otherwise use credentials if your server requires them
- Certificate: select the client certificate
- In TLS-auth: enable and specify ta.key if your server uses TLS-auth, and set Key-Direction to 1
- Add default-route to the VPN if you want all traffic to go through the VPN, or use route-only for specific subnets
- DNS: set to a reliable DNS inside the VPN if you want all DNS to resolve there
- Set up routing and firewall rules
- Ensure that traffic from your LAN destined for the VPN goes through the OpenVPN client.
- Add a route to direct the VPN network through the OpenVPN interface if needed.
- Create masquerade rule for VPN traffic to NAT outbound if you want devices on the LAN to access the Internet through the VPN:
- Chain: srcnat
- Out. Interface: openvpn-out
- Action: masquerade
- If you want split-tunneling only some traffic goes through VPN, configure firewall mangle rules or static routes accordingly.
- DNS considerations
- If you want DNS requests to go through the VPN, configure DNS servers via the OpenVPN client or set your LAN devices to use a VPN-based DNS.
- Alternatively, you can add a DNS override for VPN-connected clients to use a specific DNS server inside the VPN.
- Test VPN connection
- Use the MikroTik console or GUI to monitor the OpenVPN interface status.
- Check that the interface is “running” and that an IP address is assigned from the VPN server.
- From a connected device, test by visiting whatismyip.com to verify the public IP changes to the VPN server’s IP.
- Ping a known server inside the VPN if you have an internal VPN network address to test connectivity.
- Troubleshooting common issues
- OpenVPN interface not starting: verify certificate paths, ensure ta.key direction matches server configuration, confirm port and protocol match server.
- No route to VPN: check that the default route is set to the VPN or adjust the static routes.
- DNS leaks: ensure DNS requests are routed through the VPN DNS server or use DNS over HTTPS if supported.
- TLS handshake failed: confirm certificates are valid, ca and client certs match the server, and that TLS-auth is configured identically on both ends.
- Performance optimization tips
- Use UDP for better performance, unless your VPN server requires TCP for reliability.
- Increase MTU settings if you experience fragmentation; typical values start at 1500 and adjust as needed.
- Use a dedicated VPN interface instead of sharing the same interface for multiple VPN connections.
- For high-latency networks, consider enabling compressions if supported and secure, or avoid compression if the server doesn’t support it.
- Security best practices
- Keep RouterOS updated to the latest stable version.
- Use certificate-based authentication rather than username/password where possible.
- Enable TLS-auth or TLS-crypt if your server supports it to add an extra layer of protection.
- Disable unused services on the MikroTik that could expose your device to the internet.
- Regularly rotate client certificates and keys.
- Advanced setup: per-user access and multi-WAN
- If you’re managing multiple VPN connections, configure policy routing to select a specific VPN for certain traffic.
- For businesses with multiple WANs, set up VPN failover, ensuring that if one Internet link drops, the VPN connection switches to a backup link smoothly.
- Quick validation checks
- Confirm the VPN interface shows a VPN IP address.
- Verify that your LAN devices can reach VPN resources or the remote network.
- Check for DNS resolution through the VPN by performing DNS lookups from a connected device.

- Troubleshooting map: common error messages with potential fixes.
- Example configs: sample Mikrotik commands you can adapt to your setup.
Sample commands you might see in the MikroTik terminal
- Upload and import certificates paths may vary:
- /file print
- /certificate import file-name=ca.crt
- /certificate import file-name=client.crt
- /certificate import file-name=client.key
- Create the OpenVPN client interface:
- /interface openvpn-client add name=openvpn-out connect-to=vpn.example.com port=1194 mode=ipsec client TLS-auth=yes certificate=client.crt add-default-route=yes user=”” pass=”” verify-server-cert=yes password=”” add-dns=yes
- Set firewall/NAT for VPN:
- /ip firewall nat add chain=srcnat out-interface=openvpn-out action=masquerade
- Test the VPN:
- /interface openvpn-client monitor 0
Real-world tips from the field
- If your VPN provider uses a specific CA or intermediate certificates, make sure you bundle them correctly. MikroTik expects the exact chain you provide to it.
- If you’re supporting devices at home, a split-tunnel approach can keep local resources fast while enabling privacy for internet-bound traffic.
- Some ISP networks block or throttle VPN traffic. If you encounter issues, switch between UDP and TCP, or use a different port that’s open in your network. Also consider using a commercial VPN service that supports OpenVPN with robust customer support.

Frequently Asked Questions
How do I know if my MikroTik device supports OpenVPN?
OpenVPN support in MikroTik RouterOS depends on the model and RouterOS version. Most mid-range and newer MikroTik devices support OpenVPN client configuration. Check the router’s user manual or the MikroTik website for your exact model.
Can I use OpenVPN TCP instead of UDP on MikroTik?
Yes, you can configure either TCP or UDP. UDP is generally faster, but if you’re in an environment that blocks UDP traffic, TCP may be more reliable.
Do I need a TLS-auth key?
TLS-auth ta.key adds an extra layer of security by authenticating the TLS handshake. If your server is configured to require it, you should enable it on MikroTik and set the key direction correctly. Does Mullvad VPN Have Servers in India and What It Means for You
How can I ensure all devices go through the VPN?
Set the default route to the OpenVPN interface or create specific routes for the VPN network and use policy routing to direct traffic. You may also set add-default-route to yes in the OpenVPN client settings.
How do I test if the VPN tunnel is up?
Check the OpenVPN client interface status in Winbox/WebFig. Look for an assigned IP address and a connected state. You can also ping a resource on the VPN network or use whatismyip to verify the public IP.
How do I fix DNS leaks?
Configure the VPN’s DNS server as the primary DNS for connected devices or enable DNS through the VPN so DNS queries go through the tunnel. You can also override DNS through DHCP or static leases for DHCP clients.
Can I run OpenVPN alongside other VPN protocols on MikroTik?
Yes, you can run multiple VPN interfaces on a single MikroTik router, but you’ll need careful routing rules to prevent conflicts.
What should I do if the VPN stops working after a power outage?
Power cycles can disrupt the VPN. Recheck interface status, re-establish the VPN connection, and verify routes. Consider setting up a watchdog script that reinitializes the VPN on boot. Does nordvpn give out your information the truth about privacy
Are there performance tips for slower connections?
Yes—use UDP, avoid unnecessary TLS compression, adjust MTU for your network, and ensure the OpenVPN server is not overwhelmed. Consider enabling multi-core or device-level balancing if your router supports it.
If you want to optimize further for your setup or need a personalized walkthrough, tell me your MikroTik model, RouterOS version, and whether you’re using a commercial OpenVPN server or your own. I’ll tailor the steps to fit your exact environment.
