Subject: What free/low-cost firewall solution best for logging all traffic?
Background: We have a ADSL that we share, therefore we appear to the internet as if we all had the same IP. We have been faced with complaints from a large company that claims (most likely rightfully) that someone behind our IP number have been sharing a DVD movie to which they have the right. We don't know but most likely someone had a P2P file sharing running. We have asked people on our ADSL to stop doing that and that is the end of that - for now... We foresee the possibility that something similar might happen again. Therefore we would like to be prepared. Specifically we would like to log traffic, in a way that enable us to see who the Pirate is. This might not sound like a good idea to some people, but the alternative is that we all stand accused of being Pirates. We thought it might be possible to install some sort of free firewall, e.g. SmoothWall, on an old machine. We would then try to open all gates, turn off all security, but turn on a lot of traffic logging.
Question: Is it possible to use a firewall like that - To open all gates, but turn on a lot of traffic logging? Can SmoothWall do that? Is there a better (free) alternative?
