Configure second NIC

Hello,
my home Proxmox server is attached with two cables to my router.
One cable connects to my local network. All VMs get an IP via DHCP here.

The second cable connects to a DMZ of my router.
Here no DHCP is available. I have to manually assign static IP addresses.

Now I want to configure this second connection to the DMZ.
I have one VM that needs a static IP in this subnet.
Proxmox itself shouldn't be reachable here for obvious reasons.

How would I configure that?
I know that the physical port is "eno2". But it shows up as "DOWN":

Code:
3: eno2: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether ac:1f:6b:d9:d3:ab brd ff:ff:ff:ff:ff:ff

Should I create another "vmbr2" and attach it to "eno2"?
Then attach the VM to "vmbr2" and make static IP configuration in the VM?
Why is eno2 showing up as "DOWN"?
 
Yes, an anonymous bridge should work for that. Something like:
Code:
auto vmbr2
iface vmbr2 inet manual
            bridge_ports eno2
            bridge_maxwait 0
            bridge_stp off
            bridge_fd 0
#DMZ for VMs
