      i am using pfsense as a router with DHCP and NAT.. by default the systems behind the NAT can initiate comm tu all systems on WAN side. but i want that. any systems on WAN can initiate comm also to any system behind the NAT.

      Seems that this option was disabled according to this post: NAT 1:1 for whole network not available after version 2.4.5

      Does anyone know how to do this setup in pfsense ?

        Do you want to go over NAT or do you want to simply access devices behind pfSsense?
        Basically there is no reason to go over NAT, but if you want to go this way you might have to assign proper IPs to pfSense WAN. Simply doing NAT 1:1 without assigning IPs would only work if the traffic is routed to pfSense WAN address. I assume, that's not the case.

        Anyway if the network on WAN side is a private one as I suspect, you have to disable the blocking of private networks in the WAN interface settings and add proper firewall rules to the WAN to allow the desired access.
