I have Parallel 11 with Windows 10 installed on my Mac, but I was not able to ping the VM from my Mac. Here’s how to enable to guest machine:
on Windows, go to
Firewall > Advanced Settings > “Windows Firewall with Advanced Security on Local Computer”
> Windows Firewall Properties (link) > IPsec Settings (last tab) > Except ICMP from IPSec <— change to Yes.
To find out the ip address of your Windows VM, go to command prompt and type
you will get something like
IPv4 Address. . . . . . . . . . . : <your ip address>
