Network: please provide internal mode #4571

Open kgfly opened 1 year ago

kgfly commented 1 year ago

Currently, network only has 2 mode: share and bridged model (Mac M1 Pro. Host Mac: 12.6. VM: 12.6. UTM Version: 3.2.4 58)

Request: please provide internal mode. Etc host machine can access VM shared folder. But VM cannot access Internet.

Thanks.

Are you referring to 'host-only' mode? This is where the host can contact the VM.

'Internal' mode has traditionally referred to a mode where two or more VMs could network together, but the host could not connect. This is an important difference and a very useful mode for emulating routers and gateways.

Host-only mode. I am running UTM 4.0.9 (68) Host: macbook pro 14 inch: 12.6.1

Here is what I observed:

I do not see "Host only" option.

So is "Host only" option supported now?

Thanks.

On the mac M1 / Apple Silicon using Apple Virtualization, VZFileHandleNetworkDeviceAttachment looks promising as a way to create internal-only networks.

I am thinking something like in VirtualBox where we can create one or more named internal-only networks and then attach one or more VMs to each named network. This would allow me to analyze malware in an M1-based macOS VM that can talk to another VM (for monitoring network activity) without exposing the host system's network interfaces to the "malware" network.

Are there any plans to implement this?
