F5 APM MS File sharing

Hello guys:

I want to allow MS file sharing by providing a link in the webtop page in the APM. I am trying to achieve this by using an App Tunnel but I am not sure about the path and parameters configuration. I am trying to access a folder located in C: which name is test_folder and I configured the path of the App Tunnel as C:\test_folder. I am not sure where I am making a mistake. I am also using a port range from 1 to 1000. Am I missing anything?

I hope you could tell me if there is any other way to achieve this.

Thanks in advance.

Luis
