An interpreter pattern is a given language, defines a representation of its grammar, and defines an interpreter that uses the representation to interpret sentences in the language. The specific structure diagram is as follows:
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.
If the command in the above example does not use-s to specify the original source address in the corresponding rule, After the modification is completed, The source address in the rule you modify will automatically change to 0.0. 0.0/0 (this IP represents an IP address that matches all network segments), At this time, the corresponding action of-j is REJECT, Therefore, if the original source address of the rule is not specified when executing the above command, all IP requests will be rejected (because the original source address is not specified, the source address of the current rule will automatically change to 0.0. 0.0/0). If you are using ssh to remotely go to the server for iptables setting, your ssh request will also be blocked.
