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.
A TCP connection is a quad, and a connection is uniquely determined by the source IP, the source port, the destination IP and the destination port. Therefore, if C wants to forge the packet from A to B, it should fill in the above-mentioned IP header and TCP header with the source IP, source port, target IP and target port. Here B is the server, IP and port are open, A is the target we want to attack, IP certainly knows, but the source port of A is not clear, because it may be randomly generated by A. Of course, if we can find out the rule of generating source port for common OS such as Windows and Linux, we can still do it. In addition, we can step on the connection port of Car A through a large number of controlled hosts.

Practical Experience: I got up at 5: 30 on the morning of the 12th, because I had to gather in front of the public health building at 6: 30. This was the earliest time I got up in my college life. It was really a challenge! But I understand that the challenge is just the same as ours. After getting up, washing and tidying up, I finished the breakfast prepared the night before and arrived at the gathering place on time.
