In order to have Varnish 4 pass on the real client IP to your Apache 2.4 error log in Ubuntu 16.04 , you'll need to edit your Varnish configuration (/etc/varnish/default.vcl on Ubuntu) to add an X-Forwarded-For header. Find the vcl_recv section and added the following:
sub vcl_recv {
unset req.http.X-Forwarded-For;
set req.http.X-Forwarded-For = client.ip;
}
(Note: If you are using Varnish < 4.0 change unset to remove as the syntax is different.)
Then, open your Apache Virtual Host,
sudo nano /etc/apache2/apache2.conf
and set a CustomLog format:
ErrorLogFormat "[%{u}t] [%-m:%l] [pid %P] %7F: %E: [client\ %{X-Forwarded-For}i %a] %M% ,\ referer\ %{Referer}i"
Finally, restart both Apache and Varnish for the changes to take effect:
systemctl restart varnish.service systemctl restart apache2.service
