Sorry TheGoop, I didn't see your post until now. BitTorrent 4 is fine here, but if you want to switch to uTorrent (a very popular client!), then your ports are fine as long as you input the same port number into uTorrent when you set it up. I think uTorrent has a default set to switch ports all the time, so just go into the Preferences and tell it you want to use one port and input the port number you have already forwarded through your router/firewall. Just make sure you don't use BitTorrent and uTorrent at the same time with the same port or they will get confused.
