Iron/Mount - How can i bind external and localhost for each route?

Is there any way to allow access for external IP only for determined route?

extern crate iron;

extern crate staticfile;

extern crate mount;

fn main() {

    let mut mount = mount::Mount::new();

    mount.mount("/", staticfile::Static::new(std::path::Path::new("M:\\_users\\xinxilas\\Desktop\\ame.js")));

    mount.mount("/image", staticfile::Static::new(std::path::Path::new("M:\\Dropbox\\image")));

    iron::Iron::new(mount).http("127.0.0.1:80").unwrap();

}

I would like allow internet access for "/image", but not for "/"

i.e

fn main() {

    let mut mount = mount::Mount::new();
    let mut mount2 = mount::Mount::new();

    mount.mount("/", staticfile::Static::new(std::path::Path::new("M:\\_users\\xinxilas\\Desktop\\ame.js")));

    mount2.mount("/image", staticfile::Static::new(std::path::Path::new("M:\\Dropbox\\image")));

    iron::Iron::new(mount).http("127.0.0.1:80").unwrap();
    iron::Iron::new(mount2).http("0.0.0.0:8080").unwrap();

}

Can someone give me a tip?
