Hi,
I'm trying to set up the web application firewall for an internal webserver.
But the tricky part: I had to use the external URL for this. And that's exactly my problem.
The WAF log says:
[Tue Apr 05 13:42:19.261160 2022] [proxy:error] [pid 31869:tid 140564917860096] (111)Connection refused: AH00957: HTTPS: attempt to connect to IP-OF-URL:443 (URL) failed
Here is my Firewall rule:
And my NAT rule:
I also tried to change "Translated source to MASQ" inside the NAT rule. Without success.
The problem seems to be, that the firewall can't access the URL itself?
External and internal users can use the webserver directly (over the Firewall rule, without the WAF) without any problems.
Hoping anybody of you had any idea. 
Many thanks!
Best regards,
Daniel
