First I'll describe my setup. I have Verizon DSL. The DSL is connected to Airport Express via an ethernet cable, and I have an Airport card in my iBook for internet access. I recently installed bitorrent on my computer, and my downloads are taking forever. When I checked out the information for my particular bittorrent, the webpage indicated that I'm behind a firewall. Now I'm not sure what exactly this means or how to rectify the situation. I went into system preferences and looked under sharing. Under Firewall, it says that firewall is off. Therefore, how can bittorrent be telling me that I'm behind a firewall? Is there something I'm missing here? Any help would be greatly appreciated.
