Talk about the specific configuration and principle of the gatekeeper

A new project is about to be launched, and the equipment only has one gatekeeper. But it includes the change of users' demands on the network. It is good that all the previous projects are able to communicate. Now the security awareness of customers has also improved, and their internal information team is often trained by manufacturers. So the knowledge of technology is becoming more and more professional. I haven't blogged for months. Today, I will write down the general idea. In a few days, the company will first set up a test environment and then the whole process will be recorded in the blog. It is also a summary of my own experience.
