Able to block Network INTERFACES from communicating, not Networks?

I am asking because I am trying to set up a DMZ... The DMZ HOST actually resides ON the 'Inside' MACHINE as a VM, but from a 2nd NIC.

So, OMV eth1 is 192.168.2.181 but the VM in the DMZ is on eth2 172.16.1.2. Defeats the purpose of a DMZ if the network is allowing free open communication. What I want is CONTROLLED access via the outer 'DMZ-to-INSIDE' ACL... If I use the Firewall option on OMV It only allows me to BLOCK Networks/IP's.. But then this will block the access from the Router.

SO Can I simply block communication between the 2 INTERFACES on OMV side.

Wait what?1 I can do this?

Lemme do some googs.

Really? The KVM Plugin has 'passthrough' as an option?

Man unless I am blind mf I ain't seein' it.

Damnit. Ugh. Well unless/until OMV 7 is an upgrade option and I don’t need to redo everything imma have to wait. But at least I know, thank you

I meant like, dare I say evil windows, you just click update..For now I am gonna wait on the Upgrade because I wana make sure I make note of all the important locations and configs before I do so. Not a dis, I simply just mean I am not ready for that. and sorrrrrrrry. Been on 6 so long forgot the stupid tags!

This is INSANTITY!!!!

In my defense, I stepped away from the board and OMV [It was working flawlessly so I didn't look into it] and when I came back last week or so, I didn't realize all had progressed so far! Thank you.

I wouldn't expect to see a feature like that in a product like this.

Yes, father, you are correct.

Alright, cool, got it upgraded to 7 no issues, all works well. Thank you both for the information.

Seems though my issue is bigger/Hardware related.

Apparently I can not passthrough any NIC's at this point as the error says host does not allow/permit. It is an HPE Proliant and it is enabled via Bios, and also I added it to Grub but seems there may be more settings I need to make to allow passthrough.
