I don't think you need(ed) two public addresses to accomplish what
you want.  The ipfw divert rule can have "via <external-nic>" to
apply only to packets to/from the Internet, and you can have deny
rules for packets flowing between your two internal nets.  I don't
see a need to run two natd's here.
