Tip when you install ispconfig 3 behind a reverse proxy like nginx. In /etc/apache2/sites-available/ispconfig.conf changes '%h' to '%{X-Real-IP}i' to get this: Code: LogFormat "%v %{X-Real-IP}i %l %u %t \"%r\" %>s %B \"%{Referer}i\" \"%{User-Agent}i\"" combined_ispconfig In order to apache logs for awstats works properly. I've also defined in my /etc/nginx/nginx.conf config file: Code: proxy_set_header X-Real-IP $remote_addr; A better solution will be appreciated
