How iptables Works

iptables works by matching each packet that crosses the networking interface against a set of rules (grouped by chains) to decide what to do (called target).

rules

The iptables firewall operates by comparing network traffic against a set of rules. The rules define the characteristics that a packet must have to match the rule, and the action that should be taken for matching packets.

chains

These rules are organized into groups called chains. A chain is a set of rules that a packet is checked against sequentially. When the packet matches one of the rules, it executes the associated action and is not checked against the remaining rules in the chain.
A user can create chains as needed. There are three chains defined by default. They are:
· INPUT: This chain handles all packets that are addressed to your server.
· OUTPUT: This chain contains rules for traffic created by your server.
· FORWARD: This chain is used to deal with traffic destined for other servers that are not created on your server.
