MikroTik routers are powerful, flexible, and widely used in production environments. However, default configurations are rarely secure enough when a device is exposed to the internet.
In this practical guide, I share a production-tested firewall configuration to protect MikroTik devices against:
- DDoS attempts
- SSH and Winbox bruteforce attacks
- Port scanning
- Unauthorized management access
Inside the article, you’ll find:
- Structured firewall rules (input & forward chains explained)
- Address-list based protection logic
- Bruteforce detection strategy
- Safe rule ordering principles
- Common configuration mistakes that break connectivity
This is not theoretical networking — it's a practical cheat sheet written from a real-world IT engineer’s perspective.
