exactly what I suggested before, but the return packets will all come back 
on a single interface, unless you pass all teh packets that are going out 
one of the interfaces through natd first. That in turn breaks incoming sessions
that come in through the 'plain' interface but get outbound routed through
natd. You need to have stateful rules in teh incoming firewall that remember
that
a session was incoming and keep it from being shifted to the natd. This CAn be
done 
using NATDs stateful rules I think but I haven't done it.
