Yes, that concept is called PCP - Port forwarding Control Protocol and
being actively worked on. Still, every NAT pool IP only has one TCP port
80, so usefulness for forwarding to server services on "well-known" (not
the traditional definition of that!) ports is limited. It's more useful
to allow applications to establish an inbound path on some NAT-device
determined semirandom port, that the application can then signal to
remote folks as connect coordinates. P2P should e.g. work again using
that concept.


Best regards,
Daniel
