External only NAT for Vmware?
Posted on 2009-04-13
Hello and thank you for your time,
I have a host machine with 10 NICs and I am trying to set up a virtual Windows Domain (complete with DC, DNS, Exchange, workstations, etc) and I want it to be completely seperate from the rest of my network. I am having some trouble figuring out how to make this happen.
I have been able to make the VM's talk to eachother and the rest of the corporate network but, I want to cut off access to the corporate network. My initial thought was to set vmnet9 to be bridged directly to one of the NICs (Intel 5) and have that NIC plugged into my external firewall. However, I could not figure out what IP addresses to assign to the virtual network adapter and the physical network adapter. Let's say I want to use 172.16.1.0/24 as my virtual network address space, what IP do I assign to the physical network adapter? What IP do I assign to the firewall port? Keep in mind that there will be multiple VM's on this network, so do I need to setup NAT? If I use vmnet8, then they will have access to the internal network (which is exactly what I don't want).
Any assistance you can provide would be greatly appreciated!
