I'm about to try this one myself... but see if it helps ya....
Hello all. Everyone sais about port forwarding on your router and stuff. Yes you need to do that oubviously. Also as most people say forward random ports and not the usualy 6881 - 6999 or whatever. So for example, if you are downloading 4 torrents open 4 ports like 1000 - 1003 (4 ports).
Ok so you have done that, in bit tornado click prefrences and for port range make it from 1000 to 1003 and unselect randomize.
Ok so you have done that and thers still no god damn green light?!?!?!
Well what I needed to do was go to
www.whatismyip.com
Copy the top IP from there (at the top, it sais "Your IP is ***.**.**.***")
Then on bit tornado go to prefrences then advanced. Were it sais local ip, paste the IP into there and apply. Close all bit tornado windows and re-open and you should get the green light and good download speeds!
Please note that you wont get a green light straight away, it will take a few minutes.
Please reply if this works for you!
