Right, I agree with proxy exploit means compromised either way. Thanks for your reply.
I am trying to prevent the case where internal services that I don’t otherwise have a need to lock down very thoroughly might get publicly exposed. I take it it’s an odd question?
Re “bouncer”: Expose some services publicly, not others, discriminated by host with public dns (service1.example.com) or internal dns (service2.home.example.com), is what I think I meant by it. Hence my question about one proxy for internal and one public, or one that does both.
