Thanks. I got this working in the end. However, somewhat bizarrely
the relevant information (the internal port number) in the callback is
returned in ATTR_ORIG_SRC_PORT (etc.), despite this being what is
searched on (the external port number). I am a bit confused by this,
but it seems to work.

Thanks. Just to give you a clueless newbie's point of view, I was trying
to find either a web page, or a manpage. Doxygen would clearly help
with the latter. Even a README file that explicitly pointed at api.c
if that's where to look (the current reference is somewhat cryptic -
I thought it was to the .h files) would be a lot better than a poke in
the eye.
