Using a NAT network is a virtual network segment of VMs that can be used for direct Internet access. In some cases, however, system access in the virtual machine and the same LAN as the physical machine are required to use bridged access, so that the system in the virtual machine can also be used as a machine in the LAN as a physical machine.Solution:A) Select the system you are editing, then click Virtual
