so im working with fail2ban, ufw, and wordpress (NGINX).

I made plugin for creating 401 if someone fail to login

function wp_login_failed_403_res() {
  status_header(403);
}
add_action( 'wp_login_failed', 'wp_login_failed_403_res' );

Ofc fail2ban is installd UFW is activated.

Inside jail.local i have this

[wordpress]

enabled  = true
port     = http,https
filter   = wordpress-login
logpath  = /var/www/site.com/logs/site_nginx.access.log
banaction = ufw-nginx
bantime  = 60
maxretry = 3

Inside action.d/ufw-nginx i have this

[Definition]
actionstart =
actionstop =
actioncheck =
actionban = ufw insert 1 deny from <ip> to any app "Nginx Full"
actionunban = ufw delete deny from <ip> to any app "Nginx Full"

Inside filter.d/wordpress-login i have this:

[Definition]
failregex = <HOST>.*POST.*(wp-login\.php|xmlrpc\.php).* 401
ignoreregex =

So im trying to block myself :) i'm watching logs and i can see that nginx is registrating 401 on every single failed login.

fail2ban log says this:

UFW says this:

# ufw status                                                                              
Status: active

To                         Action      From
--                         ------      ----
Nginx Full                 DENY        ip.adress.here.xx
OpenSSH                    DENY        other.ip.adress.xxx

I can still access and login after ban (before fail2ban unban me)

Is there somthing im missing or what?

• Ubuntu 16.04
• Fail2Ban v0.9.3
• UFW 0.35
