The above diagram assumes a business scenario, which is described as follows:
The R&D engineer need to maintain the services on the Web-Service-B host. They must first login to the [ProxyJumper] server, then login to [Web-Service-A] server, and finally login to [Web-Service-B] to achieve the related business maintenance of the host.
Jump server: It is a common virtual machine with public IP and private IP, and it is the entrance of private network for maintenance engineer to login.
Around this scenario, we will introduce the configuration of [Jump server], port mapping, and Socks4/5 agent, so that users can make full use of local resources to quickly solve problems. Especially when business failures occur, the convenience of tools may become the key to quickly solve problems.
