Set up Reverse Nat

[betodiass]

Good afternoon.
I need a help, I configured a nat to redirect my external ip 187.168.xx to the local ip of my lan 192.168.xx on port 4415, the personnel access that system out by that rule, my server accepts the request when it comes of my external ip and all right, but when the server responds to the request, it leaves my internal ip instead of leaving through my external ip, does anyone know a solution?

By default pfSense translates source addresses of responses back to the external address the request was addressed to when the packets go out.
Can you provide more details?
