<![CDATA[Pfsense on Debian Libvirt and one NIC]]>Hello, All,

I wanted to install pfSense on Debian (Cockpit) using Libvirt and utilizing only one NIC.

However not sure how to setup the VM network:

Any suggestions?

Thanks

So you might want to be able to communicate with the outside world without limits.

So you should create a bridge in Debian first and then connect the VM to the bridge.

NAT means that the VM is on another subnet and the host nats the traffic.
Isolated means that the subnet cannot talk to the outside world, but only to other VMs, which are connected to the same virtual network.

Consider that you can add multiple virtual interface to the VM even if you have only a single physical NIC. For instance an isolated network to communicate with other VMs.

Any suggestions? Will it work or the only option is to have 1/2 extra NIC.
