How to use virtual machines to access hosts on the network where the physical host is

Question

How can host B access host C?

Answer 1

Simplest solution may be to not use the default switch. Create a new external vSwitch. When you create a new external vSwitch the internet protocols are removed from the adapter and the Hyper-V Extensible Switch protocol is added turning that physical port into a multi-port virtual switch. Connect your VMs to this vSwitch and use each VM's vEthernet to configure the addressing in the exact same manner as if it were a physical NIC.

or simply add your own NAT box and use external vSwitches.
