We know that IPTables acts according to rules. Let's talk about rules. Rules are actually predefined conditions for network administrators. Rules are generally defined as "if the packet header meets such conditions, this packet will be processed in this way". The rules are stored in the packet filtering table in kernel space, specifying the source address, destination address, transport protocol (such as TCP, UDP, ICMP), service type (such as HTTP, FTP, and SMTP), and so on. When packets match the rule, iptables processes these packets according to the methods defined by the rule, such as accept, reject and drop. The main task of configuring a firewall is to add, modify, and delete these rules.

Liskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types. In other words, in the process of software development, after the subclass replaces the parent class, the behavior of the program is the same. Only when the subclass replaces the parent class and the function of the software is not affected can the parent class be truly reused, and the subclass can also add new behaviors to the parent class. In order to look at an example of violation of LSP principles, the specific code is as follows:

To enter oneself for an examination in the flight college, one must first have two physical examinations 2 or 3 months before the college entrance examination. The first is the preliminary examination, which is generally divided into four major subjects: ophthalmology, otolaryngology, surgery and internal medicine. Applicants are generally required to check ophthalmology first, because ophthalmology has the highest elimination rate. Most applicants will be eliminated in this subject, and future subjects will not have to be checked. When I applied for the examination that year, there were 10 boys in the whole school. As a result, 7 boys were brushed off in the first round of ophthalmology. Ophthalmology mainly examines vision and fundus, requiring normal vision and free from myopia, hyperopia, trachoma and other diseases, as well as color blindness, color weakness and other defects. Pilots use a special "C" table to check their eyesight, with 8 directions. It is far more difficult than the "E" table.
