Trying to lock down RDS on asa 8.2

[n1fcc]

I currently have a asa 8.2 where I have port forwarded RDS .  It currently works correctly, however I need to stop allowing RDS from any address to only allow it from a single address.

access-list mail_server extended permit tcp any interface outside eq 50004
static (inside,outside) tcp interface 50004 10.1.1.73 3389 netmask 255.255.255.255

This works fine however if i try to lock it down I lose access to rds

static (inside,outside) tcp 88.88.88.88 50004 10.1.1.73 3389 netmask 255.255.255.255

did not work at all

Im confused

Can I get any help out there.  My customer is afraid of leaving the RDS port open

Is the IP address you want to allow access from 88.88.88.88 ? 

If so you do not modify the NAT statement you need to modify your acl eg. - 

 access-list mail_server extended permit tcp host 88.88.88.88 interface outside eq 50004
