I am performing malware analysis on virtual box. I want only the VMs to communicate to each other. Using host-only adapters, I have installed a Windows7 VM (192.168.56.101) with default gateway (192.168.56.102) and a Ubuntu-Remnux (192.168.56.102).
My host machine is running IP 192.168.1.3. But I am able to ping both the VMs. How can I prove that the virtual machine is isolated and does not have access to my host machine? Are there any steps that I can show to demonstrate isolation?
Or should I use Internal network? But for some reason, using internal network my Remnux machine is not getting any ip address.
