i have a netgear wireless router and do not completely understand port forwarding options. I am using bittorrent so this is rather important. I have gone into the port forward and port triggering and opened the necessary ports for bittorrent 6881 - 6999, but i have a dynamic IP address. Do i need to change the IP in my router/port forwarding settings every time??? Or are they open always? I do not havea static IP and do not know how to get one. Any help understanding would be very appreciated
