I have a stupid question.  Stupid because I have done this in the past, and cannot for the life of me remember how I did it.

I have a server on the DMZ of my ASA-5540 with an IP address of and I need it to access my SQL server on my internal protected network which has an IP address of

I thought the command(s) to do this was something like below, but it is not working, and it has been literally 5 years since I last did this, and just cannot remember.  Any help would be greatly appreciated.

access-list DMZ extended permit tcp any host eq 1433

static (inside,DMZ) netmask

Thank you for any assistance in advance,
