I know this has been asked before and I have looked through dozens of forums trying to get this to work.
Here is where I am at. I can get out to the internet. My internet works. However port forwarding does not work. I want to port forward from the outside to inside obviously. I get an error in my log file which Ill show you and then I will share the running-config
I have tried using this method found elsewhere. Id buy you a pie for Thanksgiving but hey how about a thanks and a rating?

Hello,
Do the following,
object service RDP
service tcp source eq 3389
object network inside-host
host 192.168.100.4
no nat (inside,outside) static interface service tcp 3389 3389
exit
nat (inside,outside) 1 source static inside-host interface service RDP RDP
This will make it work (what about the pie, the thanks and the rating lol )

Hi,
The way I understand the error is your testing your port-forward from a client inside your asa's inside network. By default, the appliance wont allow it. You're essentially leaving and entering the same interface
Configure U-turning or Hairpinning
11-21-2012 08:03 PM
My test is done by remoting into my work PC and from there I try to remote so it is pure external no U-Turn stuff. Is that what you were referring to? If not could you be more specific in regards to my config?

So I had to clean up my code a bit but that worked like a charm. Very good work. I feel so relieved about this. THANK YOU!
