MikroTik RouterOS

All you need to provide a reliable network connectivity

  • Connection states in RouterOS are of five types and can be used as identity indicators and traffic filtering. Using connection states, you can easily teach the router to distinguish LAN from WAN, accept trusted traffic, control the flow of unknown WAN traffic, and easily drop any type of packets that are considered invalid or simply malicious. Watch a three-part tutorial to know all about the basics of IP connections.

  • Oftentimes, you will find yourself bombarded by various types of unwanted traffic throughout the net, including offers, ads, pop-ups and so on. In MikroTik's RouterOS, there is a simple procedure that includes the torch tool and firewall configurations through which you can track down, pinpoint, and block these annoying types of traffic.

  • DoS and DDoS attacks are some of the most common malicious online activities used by hackers to disrupt a network, misuse victim devices, gain unauthorized access and so on. Using simple firewall configurations in RouterOS, you can fend off a sudden DDoS attack to gain control over your router, stop traffic floods, and make sure your hardware does not crash as a result of such cyber threats.

  • As mentioned in previous tutorials, the five main processes of the routing flow in RouterOS are prerouting, input, forward, output, and postrouting, each of which are comprised of different smaller stages. In this session, we will be configuring all those smaller steps and seeing them in action via the Log utility for the three main types of input, forward, and output traffic.

  • Continuing our introduction to firewall in RouterOS, we're focusing on the Routing Flow on Layer 3 as the overall stage in which all routing processes and decisions happen. Also, we'll take a closer look at the five main processes inside the Routing Flow, namely prerouting, input, forward, output and postrouting, detailing the smaller steps taken to complete each of them.
