Creating proxy or open VPN in mikrotik

Understanding the options: proxy vs OpenVPN on MikroTik

Before diving into steps, it helps to clarify what you’re aiming to achieve.

• Proxy on MikroTik: A proxy can be useful for directing specific traffic through another device or path. MikroTik can implement simple proxying features via its firewall and routing capabilities, or by using user-space or transparent proxy setups. A proxy is generally less about encryption and more about controlling paths and access.
• OpenVPN on MikroTik: OpenVPN brings a robust, encrypted tunnel between client devices and a server. MikroTik’s RouterOS supports OpenVPN, but it has some quirks and limitations (for example, ROS OpenVPN support is typically for client-to-site configurations and may require UDP/TCP tuning, certificate handling, and user management). OpenVPN can be deployed as a server or as a client gateway, depending on your network topology.

Key takeaway: If your goal is secure remote access and site-to-site connectivity, OpenVPN is often the more complete solution on MikroTik. If your goal is traffic shaping, filtering, or routing through a different path, a proxy approach may suffice, sometimes in combination with VPN.

OpenVPN on MikroTik: a practical setup overview

OpenVPN on MikroTik RouterOS can be used in two primary modes: OpenVPN server (gateway) and OpenVPN client (remote access). The details below reflect common, real-world patterns you’ll see in official docs and community guides.

• OpenVPN server (site-to-site or remote access): You configure a server on the MikroTik, issue certificates or use username/password (depending on your chosen auth method), and then connect clients from remote devices.
• OpenVPN client: MikroTik acts as the client behind a local network, connecting to an OpenVPN server elsewhere (for example, a hosted VPN hub or your home lab). This is useful if you want all or part of your LAN traffic to traverse the VPN.

Important notes:

• Certificate management is essential. OpenVPN on MikroTik typically uses certificates or credentials. You’ll need a CA, server cert, and client certs if you go with certificate-based auth.
• Routing and NAT: When a VPN is active, you’ll need correct route rules and possibly NAT to ensure traffic flows to and from the VPN tunnel as intended.
• Proxy considerations: If you want a proxy in front of OpenVPN (for example, to use a proxy server as a forwarder or to provide an additional layer), you must align the proxy behavior with your VPN traffic. OpenVPN itself can work through a proxy in some cases, but the RouterOS implementation has limitations you’ll want to verify in the OpenVPN documentation.

Steps to set up OpenVPN on MikroTik (high-level)

Note: Specific commands may vary slightly with RouterOS versions. Always refer to the official MikroTik OpenVPN documentation for your ROS version. Microsoft Edge have VPN built-in vs using third-party VPNs

1. Plan your topology
   • Decide if you’re setting up OpenVPN server (gateway) or client mode.
   • Decide on authentication method (certificates vs username/password).
   • Decide how you want to route traffic (full-tunnel vs split-tunnel).
2. Prepare certificates (if using cert-based auth)
   • Create a Certificate Authority (CA) on the server side.
   • Generate server certificate and key.
   • Create client certificates for each device that will connect.
3. Configure the OpenVPN server on MikroTik
   • Create a server entry with the correct port (1194 is common), protocol (UDP is common for OpenVPN), and path to the server certificate.
   • Set up user authentication (certificate-based or user/pass).
   • Enable the server and note connection details (remote IP range, DNS, etc.).
4. Configure IP routing and firewall
   • Add a server-side IP pool for VPN clients.
   • Create necessary firewall rules to allow VPN traffic and to control which subnets can access the VPN.
   • If you’re providing access to internal resources, set up appropriate NAT or routing rules.
5. Configure OpenVPN clients
   • Install an OpenVPN client on the remote device (Windows, macOS, Linux, Android, iOS).
   • Import the client certificate and key, or provide username/password as configured.
   • Point the client to the MikroTik OpenVPN server address and port.
6. Testing and validation
   • Establish the VPN connection from the client.
   • Verify that the VPN tunnel is up (interface status, IP address from the VPN pool).
   • Check that traffic is routing through the VPN as desired (full tunnel vs split tunnel).

When to use a proxy with MikroTik OpenVPN

OpenVPN can sometimes work with a proxy, depending on the proxy type and the traffic you intend to proxy. For example:

• If you need a simple HTTP/S proxy for specific applications, you can route that traffic through a proxy server that your MikroTik router can reach. The OpenVPN tunnel itself remains the secure path for the rest of the traffic.
• If your use case requires that the VPN traffic itself passes through a proxy, this is more nuanced. OpenVPN traffic is typically encapsulated, and proxies that require plain TCP forwarding can complicate the tunnel. Some deployments use a separate proxy path for non-VPN traffic or proxying management connections, rather than proxying the OpenVPN tunnel itself.

Common limitations you may encounter:

• Proxy compatibility: Not all proxy types support VPN traffic gracefully. You may need to experiment with transparent vs explicit proxies, and with different proxy protocols.
• Performance impact: Routing VPN traffic through a proxy can add latency and affect throughput.
• Complexity: Proxy + OpenVPN can introduce management complexity, especially when handling DNS resolution and split tunneling rules.

If your goal is to simplify remote access with a trusted provider, you might avoid proxy complications entirely and rely on a direct OpenVPN setup.

OpenVPN vs other MikroTik VPN options

A comparison table can help you decide which approach suits your needs.

• OpenVPN
• Pros: Widely supported, strong encryption, flexible for site-to-site or client access.
• Cons: Might require certificates, can have tricky NAT/Routing on MikroTik, performance depends on hardware.
• IPsec
• Pros: Hardware acceleration on many MikroTik devices, strong security, good for site-to-site.
• Cons: Can be complex to set up for remote access. Less flexible than OpenVPN for some use cases.
• WireGuard
• Pros: Fast, simple configuration, modern protocol.
• Cons: Not as widely supported in all older MikroTik versions. Requires RouterOS support on your device.
• Proxy-based routing
• Pros: Flexible for traffic control, can be simple for certain tasks.
• Cons: Not a replacement for encryption. Proxies introduce additional points of failure and complexity.

Practical tips and best practices

• Use a modern MikroTik device and the latest RouterOS version you can support. OpenVPN features improve with newer ROS versions.
• Prefer certificate-based OpenVPN for stronger security and scalable client management.
• Plan for DNS handling inside VPN: decide whether VPN clients should use VPN DNS or a local DNS.
• Use strong authentication for admin access to the MikroTik itself. Never expose the device with weak credentials when VPN is enabled.
• Document your VPN topology: subnets used by the VPN, NAT rules, firewall filters, and user access rights. This helps troubleshooting and future expansion.
• If you’re experimenting with proxies, start with a test network or a lab environment to observe how the proxy interacts with OpenVPN traffic.
• Consider a dedicated VPN service for clients that simplifies management and compatibility with MikroTik: a provider like ZoogVPN can be used in conjunction with MikroTik setups, particularly for end-user devices behind the MikroTik router.
