Opening PIX 525 to remote Desktop

Hi,

I wanted to open my PIX 525 so that I can Remote Desktop to any PC in my DMZ. Currently, I have only one available IP and using PAT to do this job. I thought I have done the right thing's but kept on falling. Anyone can tell me where did I when wrong...

Here the code I add to my PIX 525 :

name 10.88.88.20 IBMConsole
name 10.88.88.21 PCOne

access-list outside_access_in permit tcp any interface outside eq 3300
access-list outside_access_in permit tcp any interface outside eq 3301

static (dmz,outside) tcp interface 3300 IBMConsole 3389 netmask 255.255.255.255 0 0
static (dmz,outside) tcp interface 3301 PCOne 3389 netmask 255.255.255.255 0 0
