Managed SEP and QNAP NAS

Hi Everyone,

I have a new NAS device and I'm having trouble connecting to it using QFinder (included app with the NAS).  When I disable the firewall I am able to connect to my NAS device.  Since I'm running with managed SEP, I assume I need to take the issue back to my corporate help desk, but I'd sure like to tell them exactly what needs to be done.... or is this something I can fix locally?
