Depending on where your site is you can configure the port of entry.
If you have VPS or dedicated server you can configure the vhosts file to indicate that requests are only accessed by puerto 81 . For example:
<VirtualHost *:81>
...
</VirtualHost>
If it is a shared server you can put a rule with htaccess. For example
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.midominio.com$
RewriteRule ^.*$ "http\:\/\/127\.0\.0\.1\:2222%{REQUEST_URI}" [P,QSA,L]
127.0.0.1 is the address of your server.
