I have two virtual machines(using VMware player)
Ubuntu 14 Desktop
With Debian network access (company network + internet via proxy) works fine - out of the box (only configuring the proxy).
With Ubuntu I didn't manage it. I have to use the bridged (automatic) Network driver in VMWare, since NAT does not work.
I have also tried to configure the IP4 routing by using the LAN network connection properties of Windows (Gateway etc.).
But I only can ping from the Ubuntu guest system to my windows host, I cannot ping any other server (also in the internal network).
Does anybody have an idea what I could additionally try?
