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.

User class unified interface, User1 and User2 are different objects respectively, and they are related. If the mediator mode is not adopted, the two need to hold references to each other, so the coupling degree between the two is very high. In order to decouple, the Mediator class is introduced to provide unified interface, and MyMediator is its implementation class, which holds instances of User1 and User2 to control User1 and User2. In this way, User1 and User2 objects are independent of each other. They only need to maintain a good relationship with the Mediator, and the rest is maintained by the MyMediator class! Basic implementation:
