network-simple-single-bridge-with-nat

Enabled KVM nested capability for hypervisor installs in VMs.

This network configuration uses the proxmox/vm-external-bridge to directly attach the Virtual Machines too, and assumes the IP addressing will for the VMs will be provided by proxmox/vm-external-subnet.

This creates a secondary IP interface on the bridge device. In addition, post-up rules will be added to NAT translate outbound traffic for the VMs.

To reach connect to the VMs, you generally will have to either SSH forward to the Proxmox Hypervisor, install a VPN service of some sort on the Hypervisor, or arrange for your external Networking devices (routers/switches) to route this IP block to the addressable interface of the Proxmox Hypervisor.
