Disabling phpMyAdmin from outside the network.

Hi,

I've set up a fedora 10 server with ISPConfig.

When I go to http://ipnumber/phpmyadmin or http://website_name/phpmyadmin I get non rendered PHP code. When i use port :8080/phpmyadmin local I get the good and working phpmyadmin.

Now i want to block the phpmyadmin from outside. So that it will only be accessible from my network with port 8080.

I was busy trying stuff in
/etc/httpd/conf/sites_available/000-ispconfig.conf
and in
/etc/httpd/conf.d/phpmyadmin.conf

But I don't know where or what I need to change.
