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
