Because the setting method of the filtering function of the firewall is too cumbersome, many people do not want to use its function, but after careful study, you will find that the filtering function of the firewall is so powerful, and controllable, very detailed. The following are all actual case tests that passed 1. First plan the ob of the IP network segment to be filtered.
First: why the process of protocol hierarchical network communication is so complex that the data travels through the medium to the correct computer in the form of an electronic signal, and then converted to the original form so that the receiver can read it. In order to reduce the complexity of the network design, the protocol is designed in a hierarchical manner. Second, the significance of hierarchical design: communication

It's not a problem. understands the technical solutions of other designers that technicians disdain to talk about. In a joke, it's embarrassing for programmers with integrity to ask this question. Of course, some people think that in fact, everyone has to solve this problem, not only the security architecture design.
First of all, when I learn Juniper, I really don't know anything. It's not that I don't understand TCP/IP, but that I can't configure the Juniper router at all.
