What is one function of the firewall on a MikroTik router?

The firewall on a MikroTik router plays a critical role in monitoring all incoming and outgoing traffic as part of its primary function. It analyzes the traffic based on predefined rules to determine whether packets should be allowed through or blocked. This monitoring capability ensures that unauthorized access to the network is prevented, and it also helps to manage and control the flow of data. By tracking traffic patterns, the firewall can protect the network from various threats, such as denial-of-service attacks and unauthorized access attempts.

While enhancing the speed of packet delivery, enabling VPN connections, and automatically creating backups are important functions for network management and performance, they do not fall under the primary responsibilities of the firewall. The firewall's main purpose is to provide security through traffic monitoring and regulation, making it an essential element in maintaining a secure network environment.
