Firmware update: RouterOS 6.42




MikroTik recently released RouterOS 6.42. RouterOS is an operating system that focuses on performing router tasks, such as routing network traffic, firewall, bandwidth management, controlling wireless access points, hotspot gateway and vpn server. It can work on both the MikroTik hardware and x86 or virtual machines. A license is required for use, which is included in the purchase of MikroTik hardware. The list of changes for this issue looks like this:
