When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. 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.猫吃了舍利后成猫妖，并爱上了前来讨伐她的神仙。If the number of people who put forward the same opinion can reach three, it can be considered as convincing enough material.最理智的解决方法是杀人灭口，砍了倭女子，溺死新生儿。另一方面，东官成为了宫廷的御厨，但却受到了小小师兄的陷害。此时东官的红颜知己心茹（陈松伶 饰）怀有了皇帝（江华 饰）的孩子，害怕太后不愿接受，皇帝逼东官迎娶心茹。早已与小小结成伉俪的东官，面对爱吃醋的老婆小小，不止如何是好。不知情的小小甚至要告至公堂。/shindig (Carnival)On behalf of the monster: Lozbelen's disease ball
