Now I know NAT is out of the question, I could put my question in
another way:

The situation I have in mind is to use an embedded device as a
router, with ethernet on one end, and serial on the other end
(connected to GPRS).
There can be multiple devices connecting over the ethernet link, so
the forwarding would actually need to be able to work in this
situation too.

A connection coming in over the serial link would need port
forwarding to reach the correct address behind the router. Is that
possible with lwip?

Maybe I was unclear, lwIP does not (currently) support NAT at all.

This particular question was not about NAT, but about port forwarding.
Is that possible with lwIP?
