Help on Redirection from Port to Port for RDP

Unanswered Question
May 3rd, 2012

Hi - I have a ASA which I will post the config down below.

Basically everything is working as normal however I have just been told we have another server at host which needs to be accessed over the external IP through RDP on port 3399 which then redirects to Port 3389 if that makes sense.

So currently I have the ASA internal IP and outside let say - I have a Server at host which works perfect for RDP on port 3389 when I connect through but since I now need to RDP to a second server through I need to be able to tell the user to connect to which then will connect to and that would leave the normal connecting to on the normal 3389

Hope that makes sense - I have replaced a old DLINK which basically redirected anything on to

Result of the command: "sh conf"

Go it!


nat (webserve,outside) source static a- interface service rdp-3399 RDP-3389

access-list outside_in extended permit tcp any host eq 3389

Try it out, if it doesnt work send us the packet tracer output

packet-tracer input outside tcp 1025 3399
