As it looks, the firewall filters all IP numbers, and only a Cloudflare IPv6 IP number is communicates to the web site.
It becomes a problem because the local SPAM-filter (on the web site) cannot see the correct IP address.
If 10 different spammers connect, they all have the same Cloudflare IPv6 IP address in the log.
This means that the local SPAM-filter can’t monitor and act correctly.
Is there any setting to change this, without shutting down the Cloadflare Firewall?
