Administrative and Maintenance Tools - Proxy to Real IP Conversion

--------------------------------------------------------------------------------
This modification has been withdrawn.
vBulletin 4.0.x and 4.1.x are no longer supported.

For vBulletin 4.2.x please use the built in reverse proxy detection.
--------------------------------------------------------------------------------


This hack makes the forum always use the members real ip if a proxy is detected, meaning that all existing ip functions should continue to work, basically ignoring the proxy server (other than recording it's presence).

For example ;

* The real ip is displayed in the who's online page.
* The real and proxy server ip's are accesible for each post, the button is red for members using a proxy server.
* The real ip is searchable in the admin/mod cp (but not the proxy ip).
* The real ip can be banned by admins.

Note: This hack relies on the proxy server passing the correct http variables to allow detection.
If they are not passed then detection will not work. By definition, annonymous proxies do not pass on these variables.

If a proxy is detected, then a red ip icon is displayed instead of the standard one.

To install, download and unzip the files and follow the instructions in the text file.

This modification involves changes to the class_core.php file - if you upgrade your vbulletin, you must reapply those changes.
If you forget these edits, the modification will continue to work for forum posts only (v4.0.4 +).

would you please post (or pm) an ip that I can test to make sure your mod is working? Is "TOR" network detected ? Thanks for your nice mods !

Dear Paul M,

Today I installed Google's PageSpeed Service (not mod_pagespeed) which is an CDN just like CloudFlare. According to this FAQ the service is sending real IP headers: https://developers.google.com/speed/...s/faq#clientip.

I edited the class_core.php file correctly and installed the mod. When I create a new post on my forum, it still shows the IP address of Google's Proxy servers. How can I troubleshoot this?

The IP Address is: 74.125.17.223
The host name is: 74.125.17.223

I am using vBulletin 4.2 patch level 2. My forum is located at http://www.osx86.net.

We fixed it ourselves by editing the class_core.php bit:

// Detect ALL.
       if ($registry->ipaddress == $registry->alt_ip)
       {
           define('PROXYIP',''); 
       }
       else
       {
           $proxy = true;
           define('PROXYIP',$registry->ipaddress);
       }
       
       if ($proxy)
       {
           define('ALT_IP', $this->ipaddress);
           define('IPADDRESS', $_SERVER['HTTP_X_FORWARDED_FOR']);
       }
       else
       {
           define('IPADDRESS', $_SERVER['HTTP_X_FORWARDED_FOR']);
           define('ALT_IP', $this->alt_ip);
       }

Now the proxy details aren't written properly, but that's not that important for me. At least I see the real IP addresses now.

Seem like it does not work.

vBulletin Message only show:

The IP Address is:
The host name is:

Which is not the same as shown in the screen shot attachment of this mod.

The Real IP Address is:
The Real IP Host is:
The Proxy Server IP Address is:
The Proxy Host is:

Any advise? Thanks.

Let me give it a try..

Thank for this, i hope Paul M fix it in next release or anyone make a mod for working only vBulletin + Google Pagespeed Service...

[temsamane]

i am using google pagespeed service, and the fix of cybex is not working for me. Is there another solution?

[GamerPerfection]

I am going to try this and do what Cybex said because I started using Google PageSpeed a few days ago and only just realised that everyone is coming from the same or similar Google IPs and therefore the StopForumSpam Mod is going to let everything through registration based on IP address.

Hopefully this will fix that otherwise i'll have to scrap PageSpeed.

[GamerPerfection]

Cybex's fix seemed to fix the PageSpeed issue.

[iraqiboy90]

this solution by cyber may be working partially, but its not worth it, because:

1. .htaccess does still recognize the proxy IP, and cant ban the real IP
2. IPs not written properly which makes it less user-friendly to resolve the IP
3. some IPs are extremely not written properly. example: 2620:0:1004:2:d
