How to Access MOODLE in Intranet and Internet

When Moodle is accessed either in Intranet or internet, there will not be any issue. But occasions when the MOODLE Site has to be accessed both in the intranet and in the Internet, here is a simple trick
Server Used: IBM Blade Servers
Operating system: Windows Server 2008
Moodle Version: 2.4
WAMP Server is used.
Number of Users: 3000 (Students) + 200 (Faculty)
Open the config.php from ~/moodle/config.php
include these lines
$CFG->wwwroot = 'http://'.$server_id.'/vitcc';
$CFG->dataroot = 'C:\\wamp\\moodledata';
before the following line
$CFG->directorypermissions = 07xx;
Restart the WAMP Server and you can Check MOODLE Site both in Internet and Intranet.

The above Image tells the intranet Link and the internet link can be opened outside the campus network

Virtual Host in Bitnami Lampstack

IF you have a website that runs with an IP address and you decide to move it to a domain, then here is the clear step. Also this post will be helpful to you if you are running a same website by two different IP Address (One in campus and another outside the campus)
Prerequisites:

Your IP Address (Example): 172.16.1.10/site (Internal IP)
Your IP Address (Example): 28.45.34.101/site (External IP)

You want to move it to: example.com (instead of example.com/site)

Step 1:
Open the file /opt/lampstack-5.5.31-0/apache/conf/bitnami/bitnami.conf
In the above file, Change these lines (The bold lines are the changed ones)

<VirtualHost _default_:80>
DocumentRoot “/opt/lampstack-5.5.31-0/apache2/htdocs/site”
<Directory “/opt/lampstack-5.5.31-0/apache2/htdocs”>
Options Indexes FollowSymLinks
AllowOverride All
<IfVersion < 2.3 >
Order allow,deny
Allow from all
</IfVersion>
<IfVersion >= 2.3 >
Require all granted
</IfVersion>
</Directory>
