How to use the nginx - apache bundle on a working site as a proxy?

Question

Nginx

Please tell me, on the site domain.ru with ip 1.1.1.1 there was apache 2.2 and in the config there were such lines
ProxyRequests On
ProxyVia Block
AllowCONNECT 21 25 110 443 22 554 563 5190 1080 8080 5140 5160 4000 1478 1479 1480 8008 Deny
Order 1478 1479 1480 8008
deny from all
allow from xxx.xx.xx.xx
Apache worked as a proxy. But there was a need to install nginx.
nginx config

# user nginx;
worker_processes  4;

# error_log  /dev/null;

      location / {

            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP $remote_addr;
      }

}

server {
      listen       *:80;
      server_name   www.domain.ru domain.ru;
location /nginx_status { stub_status on; access_log off; allow 1.1.1.1; deny all; }
location /munin { alias   /var/www/html/munin; autoindex on; auth_basic "Munin"; auth_basic_user_file /etc/munin/munin-htpasswd; }
# proxy_temp_path /var/cache/nginx/domain.ru;

location / {
#            $host='domain.ru:80'
            proxy_pass http://1.1.1.1:80;
            proxy_set_header Host domain.ru;
        proxy_redirect off;
}
        
# location /administrator {
location ~*(administrator|comprofiler)* {
         proxy_cache off;
         proxy_pass        http://1.1.1.1:8181;
         proxy_set_header Host $host;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header X-Real-IP $remote_addr;

}

}
}

Now the proxy has stopped working.
Previously, on bare Apache, using the settings above, it was possible to use the site address and port 80 as a proxy by specifying it in the browser settings. To improve performance, nginx was added, but the proxy functionality fell off. Now we need to return it. Only ports 80 and 22 are open on the server, there will be no others. Tell me how to return the proxy functionality?

Answer 1

Nginx is not a proxy in the usual sense. Those. it cannot be made to work in your case in the same way as Apache.

Answer 2

Somehow I was told that nginx can work as a forward proxy. I found an example of this, but unfortunately it did not work.
