UTM - Cannot create a working VLAN between Win Server 19 and Win 11

Hi, new member here.

Trying to setup a basic home lab for practicing Win Server admin in MAC M4 using UTM. I cannot connect my Win Server with Win 11 VM using an emulated VLAN.

My setup:

1. Win Server 2019 is emulated VM:
- Has 1 network device/adapter which is Emulated VLAN (network card - virtio-net-pci)
- Connected with Host Address of 192.168.100.2 and Guest network: 192.168.100.0/24.
- DHCP start is 192.168.100.100.
- IPv4 is statically configured to 192.168.100.10.

2. Win 11 (VHDX install - not an emulated VM) -
- Has 1 network device which is in Emulated VLAN mode with virtio-net-pci network card
- Connected with Host Address of 192.168.100.2 and Guest network: 192.168.100.0/24.
- DHCP start is 192.168.100.100.
- IPv4 is configured to 192.168.100.20.

Issue - Ping requests from one machine to other fails.

I have tried switching the network card to e1000 - same issue.
Have tried e1000 on server and virtio-net-pci on Win 11 - still no connection.
Have tried leaving DHCP field as default (- some 10.0.0.2 address ?) - same issue.
Disabled firewall on both - issue presists.

Can anyone help me here please? Sorry if this has been posted previously - new member and upon searching I didn't find any matching threads.

Cheers!
