this is something I've been wanting forever. I only see my UTM's IP address and not the end users, because the UTM is proxying the traffic for those clients that are off network. Like John said, I'm constantly going to the Command window and doing an ipconfig. But more importantly, I cannot search for a computer by IP because most of them are using the same IP (due to the proxying). As Peter said, time is of the essence in many cases.
