ESXI knows nothing about DMZ that is done uplevel in your network stack.

configure physical switch to use VLANs, and then use those Tags on your new virtual machine portgroups in ESXi networking which you could then label as DMZ, that will create a DMZ for you, which is completely isolated from everything!

You will then need to be constructive with firewall rules, and routing to allow traffic in and out of your DMZ

and to be honest with you you should be using isolated physical networks, for your iSCSI traffic or VLANS

just to add to what andrew mentioned, you add a vlan (say 10) to your switches then configure the portgroups to use vlan 10

i would suggest changing your address scheme - at least your subnet mask (or do you really need 16 million addresses?) to something higher than 8.  if you don't have that many systems, use /24 as it will give you more addresses to work with on separate vlans

you can, for example, use 10.0.1.0 as your DMZ network on a different vlan then, as andrew stated, configure your firewall to route the traffic you need in and out of the DMZ

if you don't want to change the subnet mask, you could use a different address space such as in the 192.168.0.0 range for your DMZ hosts but the rest still applies for the vlan and firewall rules

this is how i have my systems configured.  i inherited a 10.4.0.0/21 network which i use for most guests then put in a separate 10.4.9.0/24 range on a different vlan for the few guests in the DMZ that are externally facing and added the appropriate firewall rules for the little access it needs

this whole project is more about network design and then configuring ESX work with it
