The Anatomy of DDoS Attacks in Local ISP Networks
Targeted attacks against local gamers or regional corporate customers can flood upstream links with UDP reflection bursts, saturating BDIX interfaces and disconnecting legitimate PPPoE tunnels.
Zero-Load Raw Table Defense
Standard filter tables consume RAM by creating conntrack state entries for every bogus packet. The /ip/firewall/raw table drops attack vectors before memory allocation, preserving total routing stability.
Dynamic Blacklisting with fiberNox
fiberNox integrates high-rate packet thresholds that automatically push malicious attack IPs into temporary blacklist address-lists, protecting subscriber nodes autonomously.
Frequently Asked Questions (FAQ)
Why use the Raw Firewall Table instead of standard Filter Rules?+
The Raw table drops malicious packets prior to conntrack inspection, saving 90% CPU overhead during multi-gigabit floods.
