Host & Guest NIC Security

Post by secretsquirrel »

Hi,

I have a W10 Host with a Linux Guest (Firewall) running.
I want to ensure that the NIC used as WAN-IN by the Firewall is not able to be accessed by the Host. Is there a configuration within VirtualBox which disables this or is that a Windows 10 configuration discussion ?
(Basically, I only want the Host to be accessible inside my home network and the Guest Firewall the only path out to the Internet.

Many Thanks

I'm not sure I understand your network setup. Are the host and the guest independent computers, or are you using the guest as a firewall for the host? Can you explain the setup in a little bit more detail please?

If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

Hopefully the attached adds clarity.
From my Cable Router, I want to have this address the assigned Guest port only. The Guest output port will connect to my internal home network. It is only from the internal home network that I want to be able to address the Windows 10 host.
That is, I do not want the Cable modem (Internet) to be able to see the Host.
