Many people on the network are saying that there is no routing, the hosts file has problems and so on. The verification has not been resolved. This problem must be related to the Internet. After troubleshooting, the failed Mac notebook is using VMware software, so there will be two virtual network cards in mischief. After viewing the routing table: Netstat-nr found that the VMNET1 network card accidentally bound a server IP address of the intranet segment, so that the Mac system means there are two routes: one is the public network exit this side of the intranet gateway, and the other is the IP address of a server in the intranet. When the Mac notebook to access a server in the intranet will go to the "second" gateway, and this "gateway" (server) is not done Ipforward and other routing policy settings, so that Mac notebook can go to access the extranet but not access to the intranet.

Workaround: 

Drop the Vmnet1 nic so that VMware virtual machines are not affected by using Vmnet8 NAT mode, and the Mac can also access the intranet. This solves the problem. Stay here and remember!

Summary:

 Encountered this problem when there is no clue, Baidu is a half-day, the argument is often the same, perhaps the parties encountered the situation can be resolved, but for their own situation or more to see some of the relevant network configuration to solve the problem.
