It it probably not the best way of going about it, but it may work out

I would like to know if someone knows some technique to discover
forwarded ports.
I mean, in instance, scanning a public IP , how we know if some port
sends responses from the connected device
(ex: a router) or from an internal host (private network).
Thanks
