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.初夏 -- 群星　　本剧投资1600万，由著名导演赖水清倾力执导，胡正言担任编剧。是继曾创下高收视率的电视剧《大脚马皇后》后的又一力作，“马皇后”从此成了中国古装剧的一个品牌。You don't cherish me nowStep 3: Do not put on the startup key/power key, and press the HOME key for another 10 seconds.
