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.像瑞星这样的大型国企，往往它的任何一点风吹草动都会改变着一片人的命运，就在瑞星曾经的辉煌消失开始亏损的时候，那些成长在瑞星的人们的命运也发生了“改制”。After the INPUT chain is emptied, there are no rules for the INPUT chain in the filter table, but it can be seen that the default policy of the INPUT chain is ACCEPT, that is, the INPUT chain "releases" all messages sent to the local machine by default, accepts all messages when there are no rules, and releases messages by default when the messages are not matched by any rules.一个已婚男人Bay（new_wongsakorn饰演）将怀孕的情人Pig（namtanlitaa饰演）带回家住，却欺骗妻子Meen（benz_punyaporn饰演）说情人是朋友的女友。但妻子早已洞悉一切，小三正妻住在同一屋檐下，开始了一场“血雨腥风”。被欺骗的爱，何去 何从。简介参考@精彩泰剧 @superM字幕组 @泰星NEW中国后援会播出平台：GMM25制作公司：Change2561
