Port conflict in App Tunnel client

Hi

 

I am using the client app tunnel app. I keep getting this error message "WARNING! The local TCP port number used by App Tunnel adapter for the application you are trying to connect to has changed due to the conflicts with another application on your local system that uses the same port..."

 

Does any one know how to configure the App Tunnel client app to connect to an alternate port?

 

Thanks in advance Henrry Pires
