title: How to set up Laravel Forge / nginx default site
body: <p>I have a nginx server with a single web site, managed by Laravel Forge.  At the moment it responds to requests for a single subdomain: subdomain_a.mydomain.com.au.  I need it to respond to requests for subdomain_b.mydomain.com.au, and also the raw IP address.  How do I do that?</p>
  
  <p>Here's the nginx config:</p>
  
  <pre><code># FORGE CONFIG (DO NOT REMOVE!)
  include forge-conf/subdomain_a.mydomain.com.au/before/*;
  
  server {
      listen 80;
      listen [::]:80;
      server_name subdomain_a.mydomain.com.au;
      root /home/forge/subdomain_a.mydomain.com.au/public;
  
      # FORGE SSL (DO NOT REMOVE!)
      # ssl_certificate;
      # ssl_certificate_key;
  
      ssl_protocols TLSv1.2;
      ssl_ciphers ECDHE-RSA-AES256-(truncated by me!!!);
      ssl_prefer_server_ciphers on;
      ssl_dhparam /etc/nginx/dhparams.pem;
  
      add_header X-Frame-Options "SAMEORIGIN";
      add_header X-XSS-Protection "1; mode=block";
      add_header X-Content-Type-Options "nosniff";
  
      index index.html index.htm index.php;
  
      charset utf-8;
  
      # FORGE CONFIG (DO NOT REMOVE!)
      include forge-conf/subdomain_a.mydomain.com.au/server/*;
  
      location / {
          try_files $uri $uri/ /index.php?$query_string;
      }
  
      location = /favicon.ico { access_log off; log_not_found off; }
      location = /robots.txt  { access_log off; log_not_found off; }
  
      access_log off;
      error_log  /var/log/nginx/subdomain_a.mydomain.com.au-error.log error;
  
      error_page 404 /index.php;
  
      location ~ \.php$ {
          fastcgi_split_path_info ^(.+\.php)(/.+)$;
          fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
          fastcgi_index index.php;
          include fastcgi_params;
      }
  
      location ~ /\.(?!well-known).* {
          deny all;
      }
  }
  
  # FORGE CONFIG (DO NOT REMOVE!)
  include forge-conf/subdomain_a.mydomain.com.au/after/*;
  </code></pre>
  
  <p>I am new to both nginx and Forge, and this is due to be in production within a few days.</p>
