By default , when you install OPnSense Firewall an dgo thrue the initial setup you define your WAN & LAN interface configuration.
All additional interfaces you define / configure start with opt and then a nr for example opt1.
I hope some one can explain why when you try to test a port-redirect rule configured on a opt<x>, interface as shown the firewall log(if you enable logging on the specific port) ,but when you do the same on the WAN port , nothing is shown and also not working ?
Should it work and is my opnsense firewall configuration a little bit corrupt / misconfigured due to all the testing and playing around with the settings or is there a good reason for why this is happening.
Sometimes you want to test this prior making this port open to the public (by creating a forwarding rule from the internet to your opnsense firewal wan interface.

Did you access the WAN from a private IP by any chance? Private IPs are blocked on WAN by default. ("block private" in the interface settings).
Also if you have an Ethernet (broadcast) network between your WAN and the default gateway and try to access services from a PC in that same broadcast domain, you need to disable reply-to.
