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.

Let's first list a column in life to illustrate the following command mode: For example, we often buy things on Tmall. Then place an order, I want to receive the goods after placing the order, and hope that the goods are true. For users, it is not concerned about how the seller delivers the goods after placing the order. Of course, the seller also has time to deliver the goods, such as delivering the goods within 24 hours. Users do not care about who the express delivery is to, and of course some people will care about what the express delivery is. For users, it is only necessary to deliver the goods within the specified time and generally receive the goods within a considerable time. Of course, the command mode also includes cancellation orders and redo orders. For example, after we place an order, I suddenly don't want to buy it. I can cancel the order or place the order again (i.e. Redo the order) before delivery. For example, I took the wrong size of my clothes. I cancelled the order and took a larger size again.
