Now, let's imagine why these "checkpoints" are called "chains" in iptables. As we know, The purpose of a firewall is to match "rules" for passing messages, Then execute the corresponding Action, So, when the message passes through these checkpoints, You must match the rules on this level, However, there may be more than one rule on this level, But there are many rules, When we put these rules in a chain, A "chain" has been formed.
