About this site

iptables.club explains iptables — the configuration interface for packet filtering in the Linux kernel (Netfilter) — through visualizations where malicious traffic is blocked in real time (simulated).

All traffic and all attacks in the animations are SIMULATION, labeled as such. Public IP addresses come only from the documentation blocks (192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24); the private-address examples use 192.168.x.x or 10.x.

The technical content about iptables comes from a single source based on the official documentation. Where something is not documented, the site marks it “to verify” and does not invent options or commands.

No trackers and no tracking cookies. The only cookie remembers your chosen language, and only if you switch it manually; theme preferences stay in your browser. The site does not collect visitor statistics.
