Networking Question

My ESX 3.5 Host has 4 installed NICS.

I want some of my images to be memebers of my DMZ subnet. Can I, and if so, how, add a 2nd VSwitch with a different IP Subnet setting without affectinaccess to/from the host using the current NIC/IP Subnet?

Thanks - Sean

I am assuming you have a spare pNIC out of the four on your esx, you don't say. Create a new vSwitch and assign the spare pNIC to it. Uplink the pNIC to the DMZ switch and make sure only your DMZ hosts use the new vSwitch. If you dont have a spare pNIC you are into VLANs to do this securely.

Yes. Create the vSwitch, assign a pNIC to it, plug the pNIC into your DMZ, and add the vmnic to this vSwitch. It will be seperate from your other vSwitches (LANs, other DMZs, etc) thus, not compromising your LAN unless your VM has a second vmnic assigned to another vSwitch.
