I am using the proxy in regular mode with server and port defined instead of transparent mode (screenshot1)
If I go and define a few services under policies instead of ANY,(screenshot2 and screenshot3)
The web proxy gets bypassed completely (screenshot4) and viruses etc pass through.
If I go back and define the services as ANY again, everything works. The proxy works as expected in transparent mode and changing services doesn't have any effects.
Tested on chrome latest, windows 10.

Bill
