Before starting the reporting, are you polling for this information? If not, I would start with universal device poller (UnDP). The OID for client connection is 188.8.131.52.4.1.34184.108.40.206.1.3.1. When I was browsing the MIB, I did not see one for TCP connections. I also did not see a Bluecoat UnDP template in the content exchange.
It takes a long time to find these specific values and I typically contact the vendor for the specific OID - it's much quicker and more accurate.
Once you're successfully pulling the information, then we can easily write a report for the undp poller information.
Hope that points you in the right direction.
