MikroTik Firewall (Starting Point)

This project provides a simple and functional example, which can and should be adjusted according to your environment’s needs.

Prerequisites

1. MikroTik RouterOS installed and accessible
2. Access via Winbox or terminal (CLI)
3. Basic understanding of firewall chains (input, forward, output)
4. IP addressing configured on interfaces

Features

• Allows essential traffic (DNS, ICMP, established/related connections)
• Blocks unwanted external traffic
• Basic protection rules for the WAN interface

Notes

This project does not cover advanced scenarios (such as NAT, mangle, VPN, or layer-7 filters). The goal is to provide a minimal secure baseline.
