The question arises when you need to use the virtual machine in the local network between host and guest host or when you connect to the active services in the guest machine. Well apparently, reading around between the forum and gaining experience with my local installation, VirtualBox creates some problems while VMWare Workstation on the first try has allowed me to connect to http to the guest machine smoothly and NAT configuration.
My goal was virtually install a full LAMP server on a Ubuntu Server distribution 14.04 64bit, and connect to http using the browser on my pc (Ubuntu 16.04 (64 bit) which it took place in a natural way using VMWare Workstation.
At this point I wonder about one thing, VirtualBox is a bug? an oversight? One problem your Linux? It seems that does not go well even if used in a Windows network.
