When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.黎章见野猪来势凶猛，躲避不及，便飞身跃起，脚尖在野猪背上一点，落在这畜生身侧。为了摆脱让它害怕的人类，小咕爬上了东京塔。夏季的烈日照得它精疲力竭。小咕俯瞰着城市，独自低语道：“哪里都找不到一个安静的地方，这里是人类的窝。我已经不行了。我要去爸爸那里……”秦枫见她想通了，便微笑道：你大可不必执着于此事，一个是小义，一个是大义，你并没有做错。
