Does anyone know if the Windows Server 2012 Network Load Balancer can (successfully) be installed on a VMware VM, placed in the DMZ, and just allow routing thru to the Exchange 2013 servers (CAS role only). I know most advise against this but I'm still waiting on the budget and MGMT approval and need a way to NLB in the meantime. Since it's in the DMZ it would be placed in a different subnet, assigned a VIP, Internal IP and public facing IP. If I can do that in can also buy just one cert and apply it to the NLB, the two CAS servers along with the SAN names. Then apply the same very to the hardware NLB once receive and maintain the IP and firewall configs.
