Using ESXi v5.1 and vSphere, my networking is setup like so:
- One standard Switch: vSwitch0
- vSwitch0 has one uplink physical adapter (Internet connected)
- vSwitch0 VM Network has 3 virtual machines (Web Accessible)
I'd like to add several "internal" VMs that are accessible only to the 3 Public facing VMs that are currently on vSwitch0. How should I do this? I know I could add a another "internal" vSwitch that is not bound to a physical uplink, then employ a "gateway" VM that is dual-homed, but it seems there should be an easier way. Can I accomplish this strictly with a networking setup? If so, how?
