False Denial of Service "IP Fragmentation Overlap" attack detected

I'm trying to use a digital x-ray machine that communicates via an IP protocol on a Windows 7 64 bit SP1 machine with Symantec Endpoint Protection version 11.0.6005.562. Every time I try to acquire an image Symantec detects a Denial of Service "IP Fragmentation Overlap" attack and blocks the traffic from the IP address for 60 seconds. This results in our machine erroring out and not acquiring any image data. Is there a way to exclude Denial of Service attacks from specific IP addresses or UDP/TCP ports (or any other way to resolve this issue)? I can change the settings for Network Threat Protection to disable denial of service detection completely, but I'd rather not do that. Any ideas?
