Varnish bunny

Drupal has a flood protection feature, which bans a user after a number of failed login attempts:

"Drupal 7 prevents brute force attacks on accounts. It blocks login by a user that has more than 5 failed login attempts (within six hours) or an IP address that has more than 50 failed login attempts (within one hour)."

With the latest update of Varnish, the configuration file has moved to a new place. This is how you do it Debian 8 with varnish 4.1.4-1~jessie:

Create folder and insert in /etc/systemd/system/varnish.service.d/customexec.conf:

sudo -i
mkdir /etc/systemd/system/varnish.service.d
vi /etc/systemd/system/varnish.service.d/customexec.conf
