I am running docker containers on windows local PC.
and set port forwarding on my local router to enable external entering.

/etc/nginx/conf.d/default.conf is below.

I tried allow xxx.xxx.xxx.xxx; and deny all;. But not worked

Now I am using if statements to allow specific IPs. But not work too.

I want to allow IPs to enter to specific url path.

How to fix it?

upstream django_server {
    server host.docker.internal:8888;
}

server {
    listen 8080;
    listen [::]:8080;
    server_name 127.0.0.1;

    location / {
        set $allow false;
        if ($http_x_forwarded_for ~ "172.18.0.1?$") {
            set $allow true;
        }
        if ($http_x_forwarded_for ~ "127.0.0.1?$") {
            set $allow true;
        }
        if ($http_x_forwarded_for ~ "127.0.0.1?$") {
            set $allow true;
        }
        if ($allow = false) {
            return 403;
        }

        proxy_pass http://django_server;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
    }
}
