This is not possible as (AFAIK), QEMU's ethernet adaptator emulation layer
has absolutely no idea on which ports the guest OS is listening to. So to do
what you want, it would entail opening all possible ports on the QEMU side
and 'forward' them to the guest OS.
This is already possible, but I doubt that you want to DoS your Linux box by
using all possible ports :-)
