I know that with the *virsh* command I can create several types of networks
(a "NAT network", for example) as we can see in these URLs...

KVM default NAT-based networking
<https://www.ibm.com/downloads/cas/ZVJGQX8E> (page 33)
*QUESTION:* How can I create a network (*lan_n*) where only guests/VMs have
connectivity, with no outbound connectivity and no host/hypervisor
connectivity?
*NOTE:* The connectivity to other resources will be provided by a
*pfSense* firewall
server that will have access to another network (*wan_n*) with outbound
connectivity and other resources.
Network layout...

_ [N] - Network;
_ [I] - Network Interface;
_ [V] - Virtual Machine.
*Thanks! =D*
