Thanks Sylvain,

There must be a way of doing this without having to do anything with my
default gateway of my physical network? . Even if I have to I do not wan to
do anything to the physical gateway. All I need is a way to let the VMs get
a dynamic IP from the physical network. How can I do this. For example this
can be done on virtual box using a bridge adapter which maps the VM in to
the physical network.
