Hi!

Can you check that windows and kali have internet access before running the attack?
Can you show the results of:
ifconfig and route -n in kali
ipconfig in windows
Can you share a screenshot of the Network settings used in VirtualBox for both machines?

Bur use screenshots please as the info you have shared is hard to read. And for the code use code button from the menu because I can’t read it properly as it doesn’t have any indentation.

Thanks!
Diego
