We host Game Servers off of Windows Server 2008 machines, and we just received a report that one of our customers is using their server to do some type of UDP attack. The person being attacked provided us with the IP address, but do to IPv4 restrictions, we have 5 Game Servers running off that IP address.
What would be the best way to figure out which game server is sending these packets? One of our other techs installed an an application a long time ago that showed live network traffic, but it isn't on this machine and I can't find it.
