Mini Mods - Prevent guests/users from using proxies at your forum

This hack will allow you to prevent guests/users from using proxies at your forum. You can dissallow proxies for the forum as a whole or to prevent only registrations with proxies. You can enable and disable it at the Acp of your forum where you can control the settings for the mod.

Note: As you know there is no such way of preventing proxies 100% but it helps a lot. I tested it with a dozen proxies and it stopped 8 of them.

Hello can you have a look at this here and i am really sorry for going on about this. http://www.vbulletin.com/forum/forum...-proxy-servers

I have added the code to my httacces file in cpanel then checked with 6 different proxy sites and you can still view my forum

My question is should this work straight away or does it take time

[kh99]

I don't know a whole lot about htaccess (or proxies for that matter), but it should have worked immediately. So you could double check to make sure that you have it in the right place and the htaccess is taking effect. Maybe there's some test rules that you could put in there to check.

I would kind of guess that a proxy service that is made for people to hide where they're coming from would not set http headers to say it's a proxy request, and in that case there wouldn't be any way to block them except to block every ip they could be coming from. But again, I don't know.

This is from your No proxy Allowed.xml

if( @fsockopen( $_SERVER['REMOTE_ADDR'], 80, $errstr, $errno, 1 ) || @fsockopen( $_SERVER['REMOTE_ADDR'], 443, $errstr, $errno, 1 ))
        {

What if i change it to

if (    in_array($_SERVER['REMOTE_PORT'], array(8080,80,6588,8000,3128,553,554))
        || @fsockopen($_SERVER['REMOTE_ADDR'], 80, $errno, $errstr, 1))
{
