limit web pages accessible from public HTTPS URL

I want to config PHP to only serve web pages from a specific folder thru
port :443. Also, only allow inside the firewall access to port 10080.

How to do that?

here is some of the config from httpd.conf:

Listen *:443 https
Listen *:10081
Listen *:10443
NameVirtualHost *:10081
Listen *:10080
NameVirtualHost *:10080
DocumentRoot /www/zendphp7/htdocs

<VirtualHost *:10080>
Include /usr/local/zendphp7/etc/sites.d/zend-default-vhost-10090.conf
</VirtualHost>

<VirtualHost
*:443>
SSLEngine
On
SetEnv HTTPS_PORT
443
SSLAppName xxxxxxxxxxxxxx_ZENDSVR61
</VirtualHost>

# Allow requests for files in document root
<Directory /www/zendphp7/htdocs>
Options FollowSymLinks
order allow,deny
allow from all
AllowOverride all
</Directory>


thanks,
