    I'm having problems with your setup. Is Application.example.com at
    193.531.43.27 or is it on the lan with an internal address?

    If it's internal, then machines on the lan can see the internal IP, so
    there's no reason for it to have a public address. If machines outside
    the lan need to get to app.ex.com, then use natd_flags in rc.conf and
    point the ports you need opened on app to the local addy of app, and use
    the NAT's external addy for the external users of app. That would be
    the easiest way if you don't want to give an external addy to app.

    Of course the easiest way is to just give app an external addy and plug
    it into the ISP supplied router. Unless app is a M$ box, of course.
