I have a remote that I can ping from my macbook's terminal. But when I start my VirtualBox Ubuntu 16.04 VM and ping the same remote host, its not pingable and I get an error saying "Destination Host Unreachable".
Also, I am on my company's VPN when I do this and the remote host is on that network.
I have been trying to look for similar issues online but haven't found anything. How can I debug this? Please let me know any information you need.
Output from my VM:
