I’m not sure what you are looking for? Are you looking for the private IP address of the guest that is downloading illegally? If so, you’re not going to get it if you are NATing their traffic so they can get out to the internet, at least not without having a one-to-one NAT for each private IP.
If you really need to keep a log of who is going to what sites and using what services, look into netflows for logging and tracking that traffic.
You’ll need a collector to gather and inspect the traffic for you. There are many open source and closed source options there depending upon the feature set that you need and what you are looking to do. On the open source side I’ve played with Ntop, NFsen, and Cacti. NFsen is the only one that has been specifically designed for netflows however.
