solution:
the default network adapter setting is NAT when i should have changed it to Bridged.
why? Here is the answer From the VMWARE manual:
Bridged networking: connects a virtual machine to a network by using the host
computer’s network adapter. If your host computer is on a network, this is often the
easiest way to give your virtual machine access to that network. The virtual network
adapter in the virtual machine connects to the physical network adapter in your host
computer, allowing it to connect to the LAN the host computer uses.
Bridged networking configures your virtual machine as a unique identity on the
network, separate from and unrelated to its host. It makes the virtual machine visible
to other computers on the network, and they can communicate directly with the virtual
machine. Bridged networking works with both wired and wireless physical host
network cards.
NAT: configures a virtual machine to share the IP and MAC addresses of the host.
The virtual machine and the host share a single network identity that is not visible
outside the network.
