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This modification has been withdrawn.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 +).

[fasters]

Not working for me.
I have follow the instruction, but nothing change.

[Paul M]

You could start by explaining what you mean by "but nothing change".

What didnt change that you were expecting ?

[jpierce]

I installed as directed, including the edits to class_core but I still only see the Cloudflare IPs.

What steps can I take to debug the issue?

Thanks!

I seemed to have fixed it by installing mod_cloudflare on the server.

Hey gang, I am a brand new VB forum owner. I have a new site. Although new, I have been a VB moderator for several years, with some Admin access. I'm on a crash course of learning. Have completed a lot of tasks.

I am very interested in this mod. I've never done a mod before and wanted to know how easy this is? I know instructions are attached in the download. Just curious what level of difficulty this mod is?

Thanks in advance.

[Paul M]

Its quite simple, one product to install, one (optional) file edit.

Not sure if you've included this information in the other versions of this modification but it would be greatly appreciated if you included where the class_core.php file was for future reference instead of having people need to search through 5 pages of comments until someone has asked about it. I'm referring to version 4200. I'm new to the vb file system so I had no clue where it was at. I'll be installing this to see if it works for me.

Imported the product, installed the icon Did the mod to /includes/class_core.php:

PHP Code:

        // set debug mode
        $this->debug = !empty($this->config['Misc']['debug']);
        define('DEBUG', $this->debug);

        $proxy = false;
        if (isset($this->config['Misc']['proxyiplist']))
        {
            $proxylist = array_map('trim', explode(',', $this->config['Misc']['proxyiplist'])); 

            if (in_array($this->ipaddress, $proxylist))
            {
                $proxy = true;
                if (isset($this->config['Misc']['proxyipheader']) 
                AND isset($_SERVER[$this->config['Misc']['proxyipheader']]))
                {
                    $altip = $_SERVER[$this->config['Misc']['proxyipheader']];
                    if ($this->input->filter_ip($altip))
                    {
                        $this->alt_ip = $altip;
                    }
                }
            }
        }
        // Detect ALL.
        if ($registry->ipaddress == $registry->alt_ip)
        {
            define('PROXYIP',''); 
        }
        else
        {
            $proxy = true;
            define('PROXYIP',$registry->ipaddress);
        }

        if ($proxy)
        {
            define('ALT_IP', $this->ipaddress);
            define('IPADDRESS', $this->alt_ip);
        }
        else
        {
            define('IPADDRESS', $this->ipaddress);
            define('ALT_IP', $this->alt_ip);
        }
        
        define('SESSION_HOST',   substr(IPADDRESS, 0, 15));
    }

As it says (in bold) in the first post ;
