Introduction
Some of you may have been wanting to use Cloudflare with your forums and noticed that it uses the IP of your server as the $_SERVER["REMOTE_ADDR"] causing issues with banning people and even displaying people's IPs. I've found a VERY simple work around and implemented it in this simple mod. It pretty much checks if the Remote address is your server IP or inside of cloudflare's ip range that they own, it will change the $_SERVER["REMOTE_ADDR"] to the Cloudflare user address.
The IP ranges in the list come from here: https://www.cloudflare.com/ips
As far as I'm aware it is 100% working.

@C. Davis: Nice mod! I noticed that you had two versions of the same mod, so I did a comparsion between both versions and found that you can merge both versions by changing this:
<file name="$boarddir/mobiquo/mobiquo.php">
to this:
<file name="$boarddir/mobiquo/mobiquo.php" error="skip">
This enables you to only distribute one package for both situations. Hope this helps you!
I installed this last week and initially all semed to be working fine then I notice one user has an IP of "0.0.0.0" showing in the users online section.
This or some other factor seems to make it generate literally tens of errors per minute.
Just a taste

When I uninstall the mod the errors instantly stop.
Conflict with another of my mods probably?
Also, your description says download v1 zip, your change log says you're at v1.2 and the actual latest version is 1.3 according to the mods page.
Make it clearer?
I installed this and my forum comes up with this
Fatal error: Cannot redeclare ip_in_network() (previously declared in /home/thexephy/public_html/originalforum/index.php:5) in /home/thexephy/public_html/originalforum/index.php on line 92
how can i fix this so i can tell my friend who created my forum, to sort it out for me.
you appear to have installed the mod twice.
You will have to manually remove the duplicated code (probably from several areas)
I get the 0.0.0.0 address too (currently for only 1 account), both on Who's Online and in Track User. No errors have been generated as of yet, however.
I'm 99.99% sure a 0.0.0.0 IP is when a user is on IPv6. If I use my account through my VPN I will have an actual IP because I connect to my site via IPv4 and when I turn off the VPN I connect with IPv6. I've tested this using a few Firefox add-ons and can easily reproduce it with other browsers and computers in the house as well. In your Cloudflare settings(Network - IPv6 Compatibility) you can turn off IPv6 if you want to test it to see if that helps with the 0.0.0.0 issue. It never bothered me so I never disabled the setting myself so I can't say for sure if it's the exact problem/solution but it's worth a try.
Nice find, I will check that out immediately.
Are the ranges hardcoded or taken from here?
https://www.cloudflare.com/ips/
Because CF will be updating the ranges soon:
https://support.cloudflare.com/hc/en-us/articles/200172456-CloudFlare-is-now-broadcasting-from-new-IP-ranges-
Looking at the IPs in their list the only new one I see is 131.0.72.0/22(since this mod only uses IPv4). I just added the following to the code for the mod in index.php.
'15' => array(
'ip' => '131.0.72.0',
'range' => '22'
),
It doesn't appear that C. Davis is still active. However, I was planning on testing this mod tomorrow and thought it would be worth mentioning that on the Cloudflare IP page (https://www.cloudflare.com/ips/), the following IP range was removed.
QuoteJun 7, 2017: 199.27.128.0/21 removed from ips-v4
Also, they have a new IP range (131.0.72.0/22). So, element 14 of the array should be updated to the following code.
'14' => array(
'ip' => '131.0.72.0',
'range' => '22'
),
If anyone has a suggestion on a better Cloudflare IP mod that's maintained, I'd also welcome suggestions.
Attempting to install this with 2.0.18 I get the following error.

Note: It appears that your database may require an upgrade. Your forum's files are currently at version SMF 2.0.18, while your database is at version 2.0.10. The above error might possibly go away if you execute the latest version of upgrade.php.
That is normally an IPv6 error SMF 2.0.x doesn't support it by default
You can also fork this as your own mod too the license for the mod allows it.
Thank you, you're right that error is related to IPv6 and CloudFlare no longer allows you to disable IPv6.
QuoteWhy can't I turn off IPv6?
At Cloudflare we believe in being good to the Internet and good to our customers. By moving on from the legacy world of IPv4-only to the modern-day world where IPv4 and IPv6 are treated equally, we believe we are doing exactly that. In the Cloudflare dashboard, IPv6 is no longer something you can toggle on and off, it's always just on.
So, I don't think I'd want to fork this mod since SMF does not support IPv6 by default. Is there a method of suggesting this mod get removed. Without IPv6 support, this mod isn't going to resolve issues for anyone running Cloudflare.
There is a mod that adds ipv6 to smf 2.0.x https://custom.simplemachines.org/mods/index.php?mod=3051
Otherwise SMF 2.1 would be the way to go
I realize this is an old topic. But I am wondering what any of you are doing if your site uses CloudFlare. I am not able to use IP addresses on our forum as they all come in the CloudFlare range. With SMF 2.1.3 now I am not longer able to use this mod. It is not compatible. Does anyone have a fix or know of a different mod that will correctly report IP addresses for users?
