iphone cannot access NAS files via PogoPlug

I cannot figure if this is a Norton Security Suite issue or my iPhone application called Pogoplug.

Here is the issue.  I have Apple application called Pogoplug.  Allows me to access files on my NAS drive (they call Cloudshare) 

I have perfect access when:  

  • My PC has a mapped drive to the NAS
  • Using my iphone's   POGOPLUG app when   - I am away from my home office WIFI  or I turn off WIFI on my iPhone while at home office

My files are seemingly blocked when I use the same POGOPLUG app, WIFI turned on, at my home-office

Ok, so I look at settings on Norton Security Suite:

  • Says it allows access to PogoPlug
  • Experiment - I turn off the firewall by    Advanced > Network > Smart Firewall  =  turn off
    • >> Result -  still files are blocked from viewing

Is this a Norton issue?   Really confused since I have conflicting information.    App access just perfect when outside the WIFI area.    Then, if I turn off the Norton Firewall -  no access to the files.    Strange??

 

Really appreciate any advice and a way to diagnose.
