Of course they will be able to see your IP, the Peer Guardian simply blocks them from viewing your shared files. AFAIK they still know your IP address, that is how they connected to you in the first place.

As for your firewall, it doesn't entirely make you invisible. It just prevents people from accessing your PC via your IP and the ports that allow connections in and out AFAIK. I could be wrong about this and if I am, I appologize.

THanks Zipp, I'll give that program a looksee.

DOWN WITH THE RIAA!!!
