Blocking VPN's

[Bow]

Yo,

I am helping my friends hotel out and he's wanting to know how you can block VPN's from accessing the client. I know Uber 2 uses this system but he uses RevCMS and it's needed to be done. Anyone know how I can go about doing this?

Thanks.

Well you could try $_SERVER['REMOTE_HOST'] It should display the VPN name and then if you have a list of most common used VPNs then you can loop through it and on a match then just block the connection.


Also I found this that might help:

$proxy_headers = array(
        'HTTP_VIA',
        'HTTP_X_FORWARDED_FOR',
        'HTTP_FORWARDED_FOR',
        'HTTP_X_FORWARDED',
        'HTTP_FORWARDED',
        'HTTP_CLIENT_IP',
        'HTTP_FORWARDED_FOR_IP',
        'VIA',
        'X_FORWARDED_FOR',
        'FORWARDED_FOR',
        'X_FORWARDED',
        'FORWARDED',
        'CLIENT_IP',
        'FORWARDED_FOR_IP',
        'HTTP_PROXY_CONNECTION'
    );
    foreach($proxy_headers as $x){
        if (isset($_SERVER[$x])) die("You are using a proxy!");
    }
