I'd like to setup a testing environment with 2 virtual machines that have access to the host, but optional access to the WAN. The WAN needs to be turned on or off depending on the testing needed. The Clients (WIN10) need to talk to each other and the Mac host even when the Mac's WIFI is disabled.
If I set the clients to use "Share with my Mac" NAT, I get the private network I need, but if I turn off WIFI on the Mac, the clients can't talk to each other. IF I run bridged, the clients MUST have WIFI. With private networking, the clients can't access the WAN
I like to achieve something like:
WAN <--> 192.168.1.1--[MAC]--172.16.67.2 <--> 172.16.67.3--[WIN1] <--> 172.16.67.4--[WIN2]
