WORKING Method { if there is no problem other than configuration }
By Default Appache is not restricting access from ipv4. (common external ip)
What may restrict is the configurations in 'httpd.conf' (or 'apache2.conf' depending on your apache configuration)
Solution:
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
at C:/wamp/www/
directory
<Directory "c:/wamp/www/">
Options Indexes FollowSymLinks
AllowOverride all
Require all granted
# Require local
</Directory>
