I'd love to - but I'm not having much success.  After much reading of
man pages (largely gobbledegook if you don't already know it) and
tutorials from
http://runtime.bordeaux.inria.fr/oaumage/oa/Teaching/ARSA_06/Shorewall/
(much
easier to understand) I ended up adding lines like

DNAT net loc:192.168.0.40 tcp 143 5143
DNAT net loc:192.168.0.40 tcp 22 5122

An attempt to restart seems to imply that I can't forward two
addresses like this, so I assume I'm on the wrong track altogether.

Before adding those lines I used to get

ssh: connect to host 192.168.0.40 port 5122: Connection refused

Now it just hangs.

Depressing :-(  This worked so easily and perfectly with the old,
unreliable LinkSys router.  Now I have to find a way to configure it
on local firewalls, and frankly I'm simply not up to it.
