[SOLVED] How to add a second network?

[szeoguprer]

My machine has multiple physical NICs.
I have two networks: A secure network and a DMZ network.

The first NIC is connected with the secure network.
The second NIC is connected with the DMZ network.

The first network is configured by default:
IPv4/CIDR: 192.168.0.2/24
Gateway: 192.168.0.1
Bridge ports: eno1

Now I want to configure the second network in the same way.
As far as I understand, I should not enter an IP or Gateway here.
So I created a vmbr1 with only one setting: Bridge ports: eno2

If I attach a VM to vmbr1 I can't ping machines in the DMZ network or the internet.
What do I miss?
