Hi.
Our company uses Intel WiDi (Wireless Display) extensively for staff to wirelessly connect their laptops to meeting room touchscreens via an Actiontec WiDi Receiver (Intel's hardware partner)
Intel WiDi uses functionality called 'usb-over-ip" (UoIP) that allows for touch input on the external display to be relayed back to the user's laptop (allowing the user to control their laptop from the meeting room display).
We are struggling to get the 'usb-over-ip' functionality to work with Symantec Endpoint Protection 12.1.6. With SEP installed on the laptop, the 'usb-over-ip' functionality appears to be blocked. If we disable SEP on the laptop (ie. reverting back to the native Windows Firewall) the 'usb-over-ip' functionality works fine.
Intel have published an 'Intel Pro Wireless Display Implementation Guide' on their website which lists the firewall ports required by the solution.
In particular, the Implementation Guide states that the usb-over-ip functionality utilises Dynamic Upper TCP ports 'above 52000' Bi-Directional. We also observe in the Windows Firewall that the WiDi agent has created a rule that allows unrestricted traffic across all ports to the 'C:\Program Files\Intel Corporation\USB over IP\bin\UoipService.exe' executable.
We've tried mirroring these configurations in our Symantec Endpoint Protection ruleset without luck.
At this time we're running out of ideas on how to troubleshoot this further. Does anyone have any suggestions ?
