I have set up a computer as an ESXI environment. The system has 1 physical network port. When I create network ports on my virtual machines, each gets an IP address assigned by my router. I need to limit the number of IP's assigned by my router to the system to 4. Is it possible to set up a virtual network that could allow groups of VM's to be routed to individual IP's for my router (and do port forwarding and such on the individual VM routers)?
My goal is the picture below:
If this is not possible, what sort of hardware would be needed in order to achieve this?
