iptables cheat sheet

Concepts

iptables defines tables, which group features:

• filter: use it to filter traffic
• nat: use it to implement NAT
• raw: use it to define which connections iptables should track (stateful firewall)
• mangle: use it to change some fields in packets (e.g., TTL)
• security: use it to define access control
