The main product of MikroTik is a Linux-based operating system known as MikroTik RouterOS. Installed on the company's proprietary hardware (RouterBOARD), or on standard x86-based computers, it turns the computer into a network router and implements various additional features, such as firewalling, virtual private network (VPN) service and client,bandwidth shaping and quality of service, wireless access point functions and other commonly used features when interconnecting networks. The system is also able to serve as a captive-portal-based hotspot system. The operating system is licensed in increasing service levels, each releasing more of the available RouterOS features. A MS Windows application called Winbox provides a graphical user interface for the RouterOS configuration and monitoring, but RouterOS also allows access via FTP, telnet, and secure shell (SSH). An application programming interface is available for direct access from applications for management and monitoring.Click on the link to Download Mikrotik.
