Sophos WAF understand

Good morning all .
I have a behavior that I cannot understand with the WAF function or maybe I did not understand how the WAF works.

On my XG I opened ports 443 and 80 to a web server.
Until then, no problem.

Following a change in the firewall rule in my company (impossible to use non-standard ports other than 80 and 443).
So impossible to use port forwarding to another server

I decided to set up the WAF.

I created a WAF rule with a certificate for HTTPS.

My problem is that this rule only works if I deactivate my firewall and my NAT rule for my WEB server

To do my tests I took care to put the WAF rule before my rule for my WEB server

Did I get it wrong somewhere or just didn't understand the principle of WAF?

thank you in advance
I hope I was clear enough

Sophos xg 18.0.5 MR-5
