ASA 5510 NAT Access Rule help for RDP protocol

Hey all. New to the ASA 5510. I set these up on my PIX 515e for years. And I did this fine the first time on the 5510 before I went back to factory default and flashed the latest 8.03 software. I somehow figured it out fine in the 7.2 software before.

I am just setting up a new office location and its LAN. I have the PAT setup and internet up and running. I simply need to setup a static NAT from the Public IP to the internal for a particular server, then allow RDP traffic coming from the outside interface to port 3389.

On my PIX and old ASA software, it would have the Source Port then the Destination Port. I would set the Source as "= any" and the Destination as 3389 and everything worked fine. Anyone see what I am missing in my config below? Thanks and sorry for my stupidity.

And yes, there is a tunnel setup wth our current office in the config.

Thanks in advance!

  If you are using the public ip that assigned to ASA's outside interface, then do the following modification

no static (Inside,Outside) tcp ************ 3389 10.100.101.1 3389 netmask 255.255
.255.255
no static (Outside,Inside) 10.100.101.1 ************netmask 255.255.255.255
static (Inside,Outside) tcp interface 3389 10.100.101.1 3389 netmask 255.255
.255.255
access-list Outside_access_in permit tcp any interface outside eq 3389

Sorry, maybe I didn't explain it correctly.

I need to add another public IP, not the IP for the outside interface of the ASA. So I need a static NAT for the new Public IP to the Internal IP of this particular server, then a basic Access Rule to allow 3389 traffic from ANY outside source to 3389 of this server.

Then...

no static (Outside,Inside) 10.100.101.1 x.x.x.x netmask 255.255.255.255
static (Inside,Outside) tcp interface 3389 10.100.101.1 3389 netmask 255.255

btw, also do the following modification, forgot to mention
no static (Inside,Outside) tcp interface 3389 10.100.101.1 3389 netmask 255.255
.255.255

Thanks, I saw that stray one before I accepted and cleared it up too.

Thanks!

The part I was missing in the ASDM was I was still doing a NAT, but you have to select PAT at the bottom of the rule windows, and set the translation and destination ports, which I got AFTER your CLI commands and I could see it in the ASDM.

Thanks again
