Thanks, in such case I do think actually adding a bridge, adding the backend interface to it, and then adding a route to the front end IP would suffice to cover that case, but I'm pretty limited with test devices so would appreciate if someone with a setup like that can test it as an alternative. Please recall that the possible gains here should be pretty significant in terms of simplification. And of course, I still also haven't had time / systems to test the NAT case...
