Yes,  This can be done.  If you are using ipfw and natd then you have to
run two instances of natd (on separate ports), one on each external
interface. The ipfw firewall rules get a little tricky but you have to
create rules to catch the incomming and outgoing traffic through each
external interface and direct it to the right instance of natd. Once
this is done then just direct your routes out the interface that you
want.
