Weird problem with NAT Reflection

[XeroX]

Hello,
so I noticed the following problem.

Before using NAT Reflection I used remapping specific domains to internal IP Adresses (my dyndns address) with Unbound and Pi-Hole. Worked perfectly, certificates valid.

I thought about using NAT-Reflection to get rid of these domain rewrites. So I enabled it and removed the DNS entries.

My Application is forwareded on Port 80 and 443.

When I enable NAT-Reflection + Create Rules and connect via Wireguard and enter for ex. x.x.x.1 to get access on OPNSense, I land on the application forwareded to 80 and 443 instead of OPNSense WebIF.

Any ideas or solution to this?

Cheers
