Can't access internet from Ubuntu installed inside virtual machine behind corporate proxy

Question

Host OS - Window 7 professional

Installed Ubuntu 16.04 inside Virtual Machine (VMWare)

While internet is freely accessible in the host OS I can't access it inside the virtual machine.

The curious thing is my company has provided a pre-configured CentOS image which inside the virtual machine can access internet.

The VMWare settings for both CentOS and Ubuntu are same. Also the network settings inside both the OS have been checked to be the same.

What can be the solution for this?

I have hidden my actual company proxy.

proxy is not installed. I can't install it as there is no internet connection.
