Working on having the right IP address in the apache logs 6 months ago
I noticed the access_log for various websites being tested on the new homeserver all had the IPv6 address of the haproxy I configured in the logs and not the original IP address. The fun bit is I have set up the right Apache mod_remoteip settings, RemoteIPHeader and RemoteIPInternalProxy and this was tested and working with Require ip rules. But it turns out the default logging formats use the %h logging variable which is not changed by mod_remoteip. Since I want IPv6/IPv4 addresses in the logs that can be resolved later I changed to the %a variable which is the Client IP address which can be changed by mod_remoteip. Changed options:LogFormat "%a %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%a %l %u %t \"%r\" %>s %O" common LogFormat "%a %{HOST}i %l %u %t \"%r\" %s %b %{User-agent}i %{Referer}i -> %U" vcommon
