Category: nat

A Raspbery Pi running (arm-)Arch sits behind my router NAT. The RasPi has a static IP 192.168.1.6 and an nginx serving on port 8093. (The nginx is listening on port 80 for another webpage.)

The server_name is “pi.hole” and it is resolved correctly by the source machine to 192.168.1.6

The interface opens successfully in my browser at “http://192.168.1.6:8093”

A “404 Not Found” pops when opening “pi.hole”

Bellow are my /etc/nginx/nginx.conf

server {
    listen 192.168.1.6:8093 ;

    root /srv/http/pihole;

    location / {
        expires max;
        try_files $uri $uri/ /pihole/index.php?$args =404;
        add_header X-Pi-hole "A black hole for Internet advertisements";
    }

    location ~ .php$ {
        include fastcgi.conf;
        fastcgi_intercept_errors on;
        fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
        #fastcgi_pass 127.0.0.1:9000;
        #fastcgi_param VIRTUAL_HOST "pi.hole";
        #fastcgi_param SERVER_NAME $host;
        fastcgi_param SERVER_NAME "pi.hole";
    }
    
    location /admin {
        root /srv/http/pihole;
        index index.php index.html index.htm;
        add_header X-Pi-hole "The Pi-hole Web interface is working!";
        add_header X-Frame-Options "DENY";
    }
    
    location ~ /.ttf {
        add_header Access-Control-Allow-Origin "*";
    }

    location ~ /admin/. {
        deny all;
    }

    location ~ /.ht {
        deny all;
    }
}

I tried adding the ip to the listener and playing with the fastcgi_param for the host name to no better end.

The user running nginx is the same for php-fpm and has ownership and read-write permissions and the root and down the tree.

What am I doing wrong?
