What are some advanced DDoS mitigation techniques using Mikrotik firewall?

Advanced techniques include using `address lists` to dynamically block offending IPs, creating `mangle` rules to mark suspicious traffic based on packet rates or other indicators, and then using those marks in `filter` rules to drop or rate-limit. Implementing `fasttrack` for established and related connections can also improve performance during attacks. For very sophisticated attacks, consider scripting to analyze traffic patterns and adapt rules dynamically.
