Hi, well apologies for bringing this issue up again but none of the suggested solutions actually does work. I tried the following output filter: ExtFilterDefine proxy_hack mode=output intype=text/html outtype=text/html cmd="/bin/sed 's/HTTP_X_FORWARDED_FOR/REMOTE_ADDR/g'" Enabling this output filter in the appropriate vhost leads phpinfo to displaying the variable REMOTE_ADDR twice and containing both the private (IP of the internal Apache server) as well as the public IP address (which was forwarded by the proxy server). I wasn't sure about the order of HTTP_X_FORWARDED_FOR and REMOTE_ADDR so I tried this as well: ExtFilterDefine proxy_hack mode=output intype=text/html outtype=text/html cmd="/bin/sed 's/REMOTE_ADDR/HTTP_X_FORWARDED_FOR/g'" This will remove REMOTE_ADDR completely. I also tried to use mod_headers but that did not work at all: Header unset REMOTE_ADDR Header set REMOTE_ADDR %{HTTP_X_FORWARDED_FOR}e That doesn't change REMOTE_ADDR at all like. So I still don't have a solution. Any input is still greatly appreciated...Thanks for your helo guys!
