NAT to Web Server running on WAN

[andy22]

Hi,
I am novice to pfsense and network topologies.
I have following setup and pfsense is running in almost default mode. I just have pfBlokerNG installed and running in default mode.

Modem --> WAN Router --> PfSense -> LAN & IOT Routers

I have a web server running on one of the WAN IP address.
When I visit my site while connected to one of the LAN or IOT router, it just times out.
As soon as I switch to the WAN router, site resolves fine.

I am sure that pfSense is blocking it but I don't know where to start and what rules needs to be defined so that I can access my web server running outside of pfSense on WAN.

I would not like to bring that web server inside my LAN and punch a hole into my firewall as much as possible.

Can someone please suggest me how can I achieve that?
Reading about NAT seems really foreign to me. By making some stupid change, I don't want to break my pfsense setup and internet to the house.

Thanks alot.

Does each of these routers NAT?

I have a web server running on one of the WAN IP address.

Where is the WAN IP assigned to? To the WAN router, inside or outside?
