      WAN subnet: 255.255.255.0
      LAN 1,2,3 subnet: N/A

      Didn't enable DHCP server cause My main router is the dhcp server

        So you are using the DD-WRT box for DHCP for the whole network but that is on the WAN side of pfSense.
        So do you have all the interfaces in pfSense bridged? You are running it as a transparent firewall?

            Ok, if all the interfaces are bridged together then only one of them should have an IP. That could be the bridge interface itself or the WAN as you have it but the others should all be type 'none'.
            Do you have firewall rules to allow the DHCP requests from the severs on the LAN? Are you seeing anything in the firewall logs?

              Allowed any protocol from the dhcp server
              But it is still not working

              I can give you Access to My firewall control panel if you want

                If you're running a DHCP server on the pfSense LAN interfaces then there are rules put in place automatically to allow the DHCP traffic. For example:

                
                # allow access to DHCP server on LAN1
                pass in quick on $LAN1 proto udp from any port = 68 to 255.255.255.255 port = 67 label "allow access to DHCP server"
                pass in quick on $LAN1 proto udp from any port = 68 to 192.168.1.1 port = 67 label "allow access to DHCP server"
                pass out quick on $LAN1 proto udp from 192.168.1.1 port = 67 to any port = 68 label "allow access to DHCP server"
                
                

                Since you are not running a DHCP server these rules will not be in place and your clients won't be able to send DHCP requests to the DD-WRT box.

                You may be better off using the DHCP relay though I've never tried it in this type of setup.

                    What did you try?

                    If you have the interfaces all bridged together try simply disabling the firewall completely, at the console: 'pfctl -d'. If you still can't get dhcp leases through it then you have some connection problem.

                      i did but still dind't get it to work
                      tried:
                      dhcp relay
                      Bridge all interface's
                      using static IPv4
                      dhcp server
                      disable firewall

                      but when i connect the server direct to my dd-wrt router it gets a dhcp adress in a few secs

                        To run as a transparent firewall you must have the interfaces bridged.

                        If you aren't running transparent then you must have a separate subnet on the lan side.
