My hunch is that we already have this case covered, but the user is
just confused. It seems to be apparent, however, that in many cases
like this, setting up the wireless access router to work as bridge
between internal interfaces would simplify the users set-up
considerably and avoid unnecessary NATting..

The number of subnets per SSID is irrelevant here because the router
has only one wireless interface and uses only one SSID.
On the other hand, the wireless access routers typically can either be
set to bridge between interfaces or route between them. The former is
simpler, and would work nicely with the below; this case is mentioned
in RFC3750. The latter appears to be what the user is trying to do..
One possible other wacky mode is "NAT everything -routing", where you
don't bridge, but the wireless router NATs every inside interface to
the outside interface..

This is irrelevant, as you wouldn't want to have multiple default
gateways in this case in any case. What you want to do is be able to
set a different subnet prefix for each subnet.

Yes, that should probably be supported. Maybe misconfiguration of the
router...
