Setting up an OpenVPN connection on a MikroTik router

← Back to FAQ

This guide will walk you through configuring an OpenVPN connection on a MikroTik router using VPNUK’s secure VPN service. Unlike traditional MikroTik OpenVPN setups, which require separate .crt, .key, and .ovpn files, VPNUK provides a single .ovpn configuration file, making setup faster and easier.

Unlike other VPN protocols, OpenVPN on MikroTik only supports TCP. If you require UDP for better performance, consider using WireGuard or L2TP/IPSec.

  2. Log in with your VPNUK account credentials.
  3. Download the OpenVPN TCP configuration file (.ovpn)
  4. Save the TCP configuration file to your computer.

2. Upload OpenVPN Configuration File to Your MikroTik Router

  1. Log in to your MikroTik router using WinBox or SSH.
  2. Go to Files in the MikroTik RouterOS interface.
  3. Click Upload and select the VPNUK TCP .ovpn file you downloaded earlier.
