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.《救救我》改编自赵锦山的网络漫画《走出世界》 ，以人口只有五万名的小城市为背景，讲述了四个无业青年在听到一个女人的求救声后，并没有对此置之不理而发生的故事。玉泽演在剧中饰演无业青年韩尚焕，是一个拥有修长的身形、帅气的外貌和温暖又乐观的性格的人物，因偶然遇见从首尔转学来的林尚美而卷入了神秘事件。徐睿知则饰演被邪教组织控制的林尚美，拥有淡雅的外貌、白皙的皮肤和沉着安静的性格的她因父亲的事业失败而从首尔转学到了乡下，之后因为家中的忧患，父亲开始依赖邪教的教主，她则开始试图从邪教中逃脱。
