New I am new to the community and trying to set up my VMware 15Pro. Currently have a WIN10 host with Pro installed, running two instances (one for Security Center, the other for Nessus) in and Air-Gapped environment (need it strictly for ACAS scanning). I am able to ping both instances from the host but unable to reach the host from the inside VM, both instances can talk back and forth. I have disabled all firewalls (windows defender and VM firewalls), and tried everything I could find via google. Any pointers you may have would be greatly appreciated.
