        That requires a masquerading router (or more generally,
        Network Address Translating) not an application level
        proxy. For example, this is a kernel level function in
        Linux whereas a user level application is needed for
        application layer proxying.

        That's not transparent.

        That can be done using bandwidth shaping in the router at
        just below the transport layer, rather than the application
        layer.
