I am currently contemplating a setup like in the drawing I made for a lab environment. I have a few questions regarding this setup. Do I need VLAN? Physical NIC 2 will probably be bridged between the subnet of the VM's and the subnet of the physical machine to be able to go on the internet?
For security reasons I am assuming that VM 2 and VM 3 will have private network settings in Hyper-V so that all traffic to these 2 machines originate from VM 1. VM 1 on the other needs to be setup with External Network!?
