So let's explain the rules of iptables in a common way. There was an analogy before, Each "chain" is a "checkpoint", Every message passing through this "level" must match the rules on this level. If there is a match, The message is processed correspondingly, For example, you and I are like two "messages" at the moment. Both of you and I are going to enter the customs at this moment. But the duke has a life, Only the imposing person can enter the customs, Those who do not meet this requirement are not allowed to enter the customs. So the soldiers guarding the customs followed the "rules" formulated by the duke. I began to look at you and me. In the end, you entered the customs smoothly, and I was rejected. Because you met the standard of "dignity", you were "released", while I did not meet the standard, so I was not released. In fact, "dignity" is a kind of "matching condition", "release" is a kind of "action", and "matching condition" and "action" form the rules.

If the message has been matched by the previous rule, iptables performs the corresponding action on the message, Even the latter rules match the current message, It is very likely that there will be no chance to perform corresponding actions on the message again. Take the above figure as an example, the message is first matched by the first rule, so the current message is "released", because the message has already been released, so even if the second rule in the above figure can match the message just "released", there is no chance to discard the message just now. This is how iptables works.
后面，是不是难免劫城了。
