Hi,
All options are set to default values.
How Wordfence gets ip addresses option is set to
Set this option if you're seeing visitors from fake IP addresses or who appear to be from your internal network but aren't.
And I've tried the other 4 options too. None of them working.
I understand that 0.0.0.0 is not a valid IP address, but my website is facing heavy attack from "An unknown location at IP 0.0.0.0 tried to access...". And before update to 4.03, Wordfence was able to block that address (it had blocked 700.000 hits from there).
Thank you very much,
Ruben
