Hi Friends!

After a couple of hours of trying and error, I am hoping to get some help here.
I am trying to configure a Port Forwarding from one pfSense Router to another through VPN connection. Some more detail on the current network:

pfSense A (192.168.2.0/24)
192.168.3.1

OpenVPN (192.168.3.0/24)

192.168.3.2
pfSense B (192.168.4.0/24)

The VPN connection is working correctly and the traffic seems to be routed correctly as far as I can tell.
I have added a Port Forwarding rule on pfSense A to forward port 80 to an IP address on the LAN network of pfSense B (e.g. 192.168.4.3) but that is not working. Port Forwarding to the LAN network of pfSense A (e.g. 192.168.2.3) is working normally.
Is there any rule I need to configure on the firewall of pfSense B?
Should I port forward to the OpenVPN interface of pfSense B and the forward again to the LAN address or should I try other VPN that offers port forwarding like this one?

Thank you all in advance for any help on this topic!

This is the main issue. You are trying to make A forward traffic to B while A and B are on two disjoint networks from an IP point of view. A can only communicate with IP addresses 192.168.2.XXX only. So it cannot send anything to 192.168.4.3.
