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 10.10.1.3 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 10.10.1.1 and outside let say 220.127.116.11 - I have a Server at host 10.10.1.2 which works perfect for RDP on port 3389 when I connect through 18.104.22.168 but since I now need to RDP to a second server 10.10.1.3 through 22.214.171.124 I need to be able to tell the user to connect to 126.96.36.199:3399 which then will connect to 10.10.1.3:3389 and that would leave the normal 188.8.131.52 connecting to 10.10.1.2 on the normal 3389
Hope that makes sense - I have replaced a old DLINK which basically redirected anything on 184.108.40.206:3399 to 10.10.1.3:3389
Result of the command: "sh conf"
