Creating a VMWare network that isolates 2 VM's [closed]

I am attempting to create a testing network for school, I am trying to create a network with VMWare that only allows those 2 VM's that would be on that network to communicate.

I am getting into malware analysis and want to make sure my system is going to be completely isolated from those 2 vm's.

I thought the Host-Only option would do what I am looking for, but I guess my host PC is still able to communicate with those VM's

Any help/suggestions would be great!

Thanks!
