Overview
---
There is a machine—which has one NIC—has 6 virtual machines. Let's
call them *vm1*, *vm2*, *vm3*, *vm4*, *vm5*, and *vm6*.
*vm1* and *vm2* should have public IP address. *vm3*, *vm4*, *vm5*, *vm6* do not
need public IP address, but should have both Internet connection and
local area network.
Here is a graphical model.
