Presenting different content based on origin of request

The code block below assumes that static landing pages in /usr/local/www/html are being served. For the trusted network (10.1.1.0/24) the landing page will be index.html (the default). For the untrusted network (anything else!) the landing page will be untrusted.html.

mydomain.com {
  @trusted {
    remote_ip 10.1.1.0/24
  }
  @untrusted {
    not remote_ip 10.1.1.0/24
  }
  root * /usr/local/www/html
  file_server @trusted
  file_server @untrusted {
    index untrusted.html
  }
}

Can this be simplified any further?
