Reverse lookup IPs in connections under firewall

Hi, I cannot find anything about this topic or maybe Im not looking in the right place.

If I want to see all the connections that a specific client makes I go to connections under firewall right? But I want to take it a step further, how do I see the DNS names (reverse lookup or NSlookup in windows) of the IP/site the client is connected to?

Instead of manually doing it I would like to see client A is connected to applications.facebook.com and then block it under content or use it for more data mining.

Yes please, I also need this. How would I go about it? The IPs doesn’t really tel you anything about a users internet behaveour and should his access be stopped or filtered…

I try to imagine what will happen if ROS will try to reverse lookup src and dst addresses for at least ~10.000 connections… %)
