VM don't getting Dynamic DHCP Lease instead of Static

[Kabun]

Hello I hope you will be able to help me.

At first I think that I have to explain a bit of my network configuration because it is kind of complex. I have multiple interfaces on one singe bridge that connect the 4 ethernet ports. The interfaces match to different networks. For example the server interface has the network 10.0.100.0/24 assigned to it and the guest interface 10.0.200.0/24.
The DHCP server is configured to only give dynamic leases to the guest interface so only static leases gets your device into another network.


Now the actual problem:

I tried to install an Ubuntu 20.04 LTS on my Proxmox server.
Before I started the VM I copied the mac address and setup an static DHCP lease in my OpenWRT router.

However while and after the installation the VM didn't got the IP that I assigned to it by the static DHCP lease (should be in the 10.0.100.0/24 network) but a IP address in the dynamic range of the DHCP server (an address in the guest network 10.0.200.0/24).

Network Model is VirtIO and CPU type is qemu64.
Proxmox Version is VE 6.3-2

Im having a strange bug in my DHCP server I tried to setup an static lease with different name and IP and I got it this time. Not shure what is wrong with it tough.
At leased it is not a problem with Proxmox so this thread could be deleted.
