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.

The combination mode is also called part-to-whole mode. The combination mode combines objects into a tree structure, which is used to represent the relationship between the whole and the part. The combination mode enables clients to treat individual objects and combined objects equally. For example, in. NET, simple controls such as WinForm controls, TextBox and Label inherit from the Control class, while composite controls such as GroupBox also inherit from the Control class. The specific structure diagram of the combination mode is shown below.
