How would I secure /netdata, or Netdata for Laravel?

Question

I'm following the following guide for installing Netdata on Laravel Forge. Basically, it's opening the port 1999 used for Netdata and redirecting it to /netdata directory.

location = /netdata {
  return 301 /netdata/;
}

location ~ /netdata/(?<ndpath>.*) {
  proxy_redirect off;
  proxy_set_header Host $host;

  proxy_set_header X-Forwarded-Host $host;
  proxy_set_header X-Forwarded-Server $host;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_http_version 1.1;
  proxy_pass_request_headers on;
  proxy_set_header Connection "keep-alive";
  proxy_store off;
  proxy_pass http://netdata/$ndpath$is_args$args;

  gzip on;
  gzip_proxied any;
  gzip_types *;
}

upstream netdata {
  server 127.0.0.1:19999;
  keepalive 64;
}

I already have an auth middleware defined, and how would I only allow people that pass the auth middleware to visit the /netdata route? The guide suggests only limiting it to one IP address, but that's not possible as I move around quite a bit.

Although I have no experience with Laravel or Forge, according to this piece of documentation, you have to define that functionality in your middleware. In essence, you instruct the middleware to perform a redirection only in case of successful authentication.

Perhaps you could instruct Laravel to redirect all connections (if auth is successful) to the NGINX endpoint (/netdata) which you will configure to only allow from localhost. Thus, a user will not be able to access /netdata, unless he/she is authenticated via the Laravel Middleware and then redirected from that middleware to the Nginx server.
