How to make a DNATed SQL server

Chettam
Hello,
I'm searching for a solution to access from an SQL aplication in my DMZ to an SQL server in my internal network. This solution is very important for me because i'm looking for that before purchasing  ASL 3.2
For the moment i do that configuration:
i create a service call sql  port 1024/65536
I make a DNAT rule:
PreDNAT any -> DMZ NIC  service sql
PostDnat no change -> internsql server service sql
i make 2 packet filter :
any -> sql -> DMZ NIC
any -> sql -> sql server
but it doesn't work 
can somebody help me ?
thanks for your answer

    You must define service:
    "MS_SQL" tcp (S/Port)1024:65535  (D/Port)1433:1434

    Packet Filter Rule:
    From: "DMZ_SQL_Client" Service: "MS_SQL" To: "Internal_SQL_Server" Action: Allow 

    You don't need from any DNAT configuration.
