Error 403 - Forbidden blocked IP not correct

Worker Joined: May 26, 2006 Posts: 153

I have just spent a number of hours trying to find out why I was banned from my website, both as a visitor and admin. I was banned both from my home PC work PC and mobile phone, so assume everyone was getting the same thing.

The page was displaying the following:

Error 403 - Forbidden etc. with an IP address shown that was not the one I was using. After spending ages switching out nuke via the database and checking for problems in bvoth database and htaccess files, etc. I finally realised the IP address shown was in the banned list so removed it. Can now get into the site again.

Does anyone know why the site would ban someone like this when the IP address was not the one they are using. It didn't make any difference if I accessed the site via pagewasher.

Thanks.

Here we go. I'm a Linux type of person and I upgraded a few things on my localhost today to include Raven Nuke. I am now being blocked from doing anything with RN. I have run my server for a long time and this is my first encounter with this script. Thanks for your help in advance. Smile

$ip = $_SERVER['REMOTE_ADDR'];
if(!ereg('^([0-9]{1,3})\\.([0-9]{1,3})\\.([0-9]{1,3})\\.([0-9]{1,3})$', $ip)) die('Nice try!!');
