In the lab, because the internal lan has the IP address of the network segment 192.168.1.0, if you want to connect to the Internet, you need to change the IP address to the network segment 172.16.20.0. The network segment 192.168.1.0 can access the instructor's FTP, 172.16.20.0 can access the Internet. I need to use both CIDR blocks. It is very troublesome to set them. Therefore, bind the NIC to multiple IP addresses. In RHEL, there are two ways to bi

With regard to the virtualized network of Windows Server, the previous configuration changes that occurred at the operating system level were described. Some of these configurations are implemented through widgets provided by Windows Server, such as the configuration of NIC groups, and some require server roles such as Hyper-V to install Windows Server, and then through Hyper-V Manager or its command-line tool to configure the virtual switch. But for global configuration management and implement
