Hi,

I would solve this in the following way:

1. configure 2 logical networks with vlans
e.g. lan1 (vlan id 100, ip network 10.0.0.0/24), lan2 (vlan id 200, ip
network 10.0.1.0/24)
2. assign vnics of vms to corresponding logical network
3. create firewall rules on firewall to allow/disallow communication (fw
must be in both vlans)

Hope this helps.


Regards,
René
