Hi,
We are running SMF 2.1.4. We are behind a Securi firewall at GoDaddy. All users are showing the Securi IP.
We went to Admin > Maintenance > Security and set "Reverse Proxy IP Header" to "X-Forwarded-For" which according to Securi documentation is the right setting to show client IP. But it didn't change anything.
Any other suggestions what we should try? Should we update the setting in the php.ini?
That's a known issue #7684 (https://github.com/SimpleMachines/SMF2.1/issues/7684)
The best solution I know would be to handle this on the server level, for example in Apache with mod_remoteip https://httpd.apache.org/docs/2.4/mod/mod_remoteip.html
Some discussion and possible solutions also in Reverse Proxy IP Header selection not working (https://www.simplemachines.org/community/index.php?topic=585020.0)
Ahh, I didn't realize it was a known issue. Yes I can do it the Apache mod_remoteip route. Thanks!
