Ban Proxy Surfers?

I did a search and found nothing that would help...

These are my issues:

1. I have a couple of banned users that continue to access our site by using Proxy Servers.
2. It is not a big deal if Proxies can see the site, I just don't want them being able to post.

I need this product to protect our site and our users. Proxies are good, but when banned members use them to create kaos within our board that is not good.

any ideas on what can be done?

this would be a great thing

I know there is a site at www.elitehackers.com (a bunch of kiddies that have no real clue) they have this feature in place where you can't post from a proxy

The only way I see of doing it would be to get a list of proxies out there, then add all their IPs to your banned IP list.

you can check the HTTP referrer session variable, if it's set, dont allow them access, simple worked like a charm on my board software

sorry should have been clearer, have a look at this code, might come in handy

PHP Code:

if ($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"] != ""){ 
$ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]; 
$proxy = $HTTP_SERVER_VARS["REMOTE_ADDR"]; 
$hostname = @gethostbyaddr($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]); 
}else{ 
$ip = $HTTP_SERVER_VARS["REMOTE_ADDR"]; 
$hostname = @gethostbyaddr($HTTP_SERVER_VARS["REMOTE_ADDR"]); 
}

where do i put that?
global.php?

okay, so I check yes to referal in the control panal, but where do I place this code. and what happens if they try to post from a proxy, do they get sent to another page telling them what they are doing wrong?

depends what you do with it....
put the entire bit of the code in a place where itll always be called...

then after the code put this:

PHP Code:

if(isset($proxy))
{

die("SORRY, ACCESS FROM A PROXY IS FORBIDDEN!");

} 


or something like that...

Don't all AOL users go through a proxy? You'll be cutting off a lot of (potential?) users.
