Ask your bosses son a question

Existing my PC (wi-fi). A, installed on A virtual machine B (centos7, NAT mode with A section, A gateway for 192.168.1.1, B 192.168.1.2 instead), and C in A Linux server, network 192.168.88. X

The situation is, B can access the network normally, can ping C and C in the same network segment LAN device, but not A, in turn, Cping impassability B, also can't A

A can also be by connecting tool normal SSH to C and C in the same network segment equipment
