I am running an Ubuntu 13.04 in the VirtualBox on Windows7. The network option is NAT.
The problem is I can use apt-get command to get some package on the internet like : curl. I can access those share computers on my Win7.
it is really wired that I just sent an email using Thunderbird. But I can not access internet through Firefox.
However, I can not access the internet through Firefox. And no response while ping www.google.com.
