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This modification has been withdrawn.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 +).

quick question Paul, im unsure if I've got this working ok.

If this is installed ok (ive edited the core file, and installed it successfully), should i see 4 options instead of 2 when I click to see someones IP address? At the minute I still only see 2, but my understanding is i should now see 4, but two will be blank if the IP address is not transmitted through the proxy?

[Paul M]

No, you will only see four if a proxy was used and detected.

Tried installing this to fix my issue here: https://vborg.vbsupport.ru/showthread.php?p=2415510

When I view the people online they are all still sharing the Google IP address. Could I have done something wrong?

Seconding on the Google Pagespeed thing.

I installed Pagespeed yesterday, today a ton of people getting logged out. I have installed this and applied the fix above....but I still only see google IP's.

edit: looks like it worked...just had not heard from members. My logins log started showing different IP's right when I uploaded the updated class_core.php, but the IP button still shows the google. No big deal.

[smirkley]

Paul,... I have this installed.

Question is, does this work for tor connections?

I have a member that has shown it not to detect tor connections as proxy at all.

Maybe because of the mechanism used. I dunno.

[muimui]

paul,i use china proxy.but real ip not detect.its still work at 4.2?

How did you get this to work? I can't even see the IP button on my forum?

       {
           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.

Think this has worked for me. Thanks

Here Paul, I helped you with your image a bit. From 133 to 119 bytes.

Other than that thanks for the mod, I'm trying it right now as I'm using google PSS and it is referring all of google's proxys instead of the true members ip addresses.
