I'm about to setup a Windows 10 (or 11 haven't decided) VM. I have two spare Sata SSDs. I was going to install the VM on one instead of a vdisk and use the second as a data storage disc for the VM. The VM will also have a separate passed through NIC on a different subnet which goes to a dedicated VPN port on my router (goal is to prevent potential virus affecting the shares - so files sit on the VM after download until I screen and move them over). How would I move data from the passthrough storage disc to the server share itself? If I map a drive - will the data flow out from the dedicated VM NIC thru the VPN and back thru the router into the unraid NIC. I'd rather not and have the data stay local. Thanks in advance.

Since my MB has two network ports and my SFP28 card has two ports, if I create a third subnet with a direct connection between the VM NIC and MB NIC (ie a third network connection) then I should be able to share across this? I would need to make sure that the VM cannot get internet access from this 3rd connection.

 

In Unraid - can a two port card be setup with two different subnets (ie same iommu with two separate subnet addresses)
