I have tried the Bad Behavior mod but it doesn't work. Bad Behavior mod settings:
Enable Reverse Proxy: On
IP call to Reverse Proxy: CF-Connecting-IP
Also see someone else with this problem: http://www.simplemachines.org/community/index.php?topic=532447.msg3783480#msg3783480
I do not want to debate the usefulness of CloudFlare here.
Edit: Adding this to the top of my index.php file fixed it without the need for a mod:
if($_SERVER['HTTP_CF_CONNECTING_IP']){
$_SERVER['REMOTE_ADDR'] = $_SERVER['HTTP_CF_CONNECTING_IP'];
}

IIRC, CF has a SMF mod at their site that fixes this issue ;)

I have tried the Bad Behavior mod but it doesn't work. Bad Behavior mod settings:
That setting in Bad Behavior is only for when Bad Behavior does a search. The settings allow the correct IP address to show up in the Bad Behavior visitor log. The Bad Behavior setting has absolutely nothing to do with any other log that is not part of the mod.
You will need the Cloud Flare for SMF mod to view SMF logs.

How about this?
"If you can't install mod_cloudflare, or if there is no plugin available for your CMS platform to restore original visitor IP, you would want to put this code in your site in or before the <body>:"

Can it use for smf? and what file should be fix?

Thought I would add to the thread here, I realize it's old, but this comes up on google results.
Put this in Sources/QueryString.php just before where it checks if $_SERVER['REMOTE_ADDR'] is set. On SMF 2.1 RC2 this is line 251
This will make the entire board compatible with cloudflare without any other mods or server config as QueryStrings is the first Source loaded.

2.1 has functionality for this in the Security page... where you can select which one you want to use, including CloudFlare...

Hi, has been included in RC3?
Even if I select "Reverse Proxy IP Header: CF-Connecting-IP" with 2.1 RC3 I only see cloudflare IP.
Thanks

what version of RC3 are you testing? the distributed one form this site or the one from GitHub that is almost RC4?
According to the merge note, it was not merged until October...

Hi Kindred, I'm using the distributed one form this site.
There is the option but it doesn't work correctly.

Hi Kindred, I'm using the distributed one form this site.
yup, and that is the "issue" -- that release was made before the merge.
There have been several hundred commits since the RC3 release on this site. During Beta dn RC time-periods, the download from GitHuib is almost always a better option.

OK, I applied this change https://github.com/SimpleMachines/SMF2.1/pull/5732/commits/5a5dee8e33e66fff883ba587e3c98418dede6d97 to QueryString.php but it still doesn't work.
I also cleared the cache (SMF + CF)
Can you confirm that with the github version it works correctly?

Also with RC4 I see only Cloudflare IPs, has anyone tested this bug?

I can also confirm that using RC4 prior did not fix it.

Beyond that, I've been having extreme difficulty finding any information on the subject outside of this topic. I do see the field for setting specific proxy servers for security purposes, but the wording appears to make that optional for better security, and I haven't messed with it yet because I would prefer to get the actual system working first before messing with it more. ;D

I swear shadav had a post on this outlining a fix for CloudFlare but I cannot find it.
@shadav? Are you aware of a fix for IPs under Cloudflare? Or did you fix it by a call to Cloudflare?

lol I think you are thinking about my modem connection issues where I had to change my dns settings use cloudflare ip address or another service because my internet provider (xfinity) sucks
for me on cloudflare I had to turn off Rocket Loader under the optimization settings other wise it messed up my sites (couldn't use the menu, etc)
also turn off Mobile Redirect
as for ip, I don't recall off the top of my head
running a quick search there's this mod for 2.0.x
