NGINX only for forwarding to LAN

[pixel24]

My mistake! On IPFire (running NGINX) port 80 was closed. Now I'm a little
closer. With:


worker_processes  1;
events {
    worker_connections  1024;
}

http {
    server_names_hash_bucket_size 64;
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    server {
        server_name gw.mydomain.com;
        location / {
                proxy_pass http://192.168.24.109;
        }
    }
}

I can connect from the outside to the web server :-) What surprises me
however is that in the address line of Firefox my external WAN-IP of the
firewall is located afterwards. Is this normal an ok?
