well if you have more than one computer behind the router, check your IP address (Start --> Run --> Command --> "ipconfig") and see if it's one of the RFC1918 "private addresses"... chances are it'll be a private C: 192.168.***.***. if so, then you know your router has NAT. most home routers do, that'd kind of the point of them. and NAT usually works hand-in-hand with PAT (hence the "NAPT")
I knew you were behind a router, because that's a typical problem you're having from behind a router.
Remember those ports i gave you (check my previous post, or the one before it) well those are the ports Bittorrent communicates on. i'm pretty sure anyway, i remember reading about it a while ago, although i've never used Bittorrent personally. What's happening at the moment, is your router's NAT firewall is blocking those ports. the router doesn't know what computer to forward information coming in on those ports to. Now what i'd recommend doing, is set a static IP address for yourself on the router, so your IP address will never change. when you get that working, there should be something in your router command webpage thingy to do with Port forwarding, translation, Firewall, etc. In one of those, there'll be a screen that looks something like this:
as you can see basically it binds a port to a certain computer. you want to make sure your computer's on a static ip address though, in case your router's DHCP assigns you another address, which is unlikely, particularly if you're using only one computer through the router, but possible. Have you ever wondered why "Direct connect" doesn't work on AIM when you're behind a router? well this is why.
Now that you understand the concept, I took the liberty to do some research for you regarding port forwarding on the Alcatel 510, which i'm not familiar with... this page describes in detail how to bind ports to IP addresses, follow its instructions, and you should be fine:
