Hello sir,
I followed exactly same steps as you told in video lectures.Although i created fake AP but i am unable to give internet service to it.As a result whenever any device connects to my fake AP,it does not have any internet service in it.
1. Host connected to my fake AP is not directed to my server’s index.php.Rather an error is shown on his screen that ‘site can’t be reached’
2.UNABLE TO RESTART dnsmasq (unable to run : dnsmasq -C <dnsmasq.conf file path>)2nd time after running ones.I face the following error whenever i edit dnsmasq.conf file and try to run same command again:

ERROR : dnsmasq: failed to bind DHCP server socket: Address already in use

*For now i need your help primarily to provide internet access to client connected to my fake AP
PS: I used exactly same conf file and same ip granting commands that you used to created fake AP.
