WORKING Method (unless there is no other problem)
By default, Apache is not restricting access from IPv4 (common external IP address)
What are restricted are the commands given in 'httpd.conf
'.
Replace all
<Directory />
AllowOverride none
Require all denied
</Directory>
with
<Directory />
AllowOverride none
# Require all denied
</Directory>
hence removing out all restriction given to Apache.
Replace Require local
with Require all granted
for the C:/wamp/www/ directory.
<Directory "c:/wamp/www/">
Options Indexes FollowSymLinks
AllowOverride all
Require all granted
# Require local
</Directory>
