what torrent client are you using? go into its properties or setup and try to find what the port it is using.
some can use ports like 6888 6889 etc.. or some can use 12700-99999. or whatever.. so try to identify it. once done, type in your ip in the browser. for example if your with linksys.. its usually 192.168.1.1 .. etc..
do you know your ip though?
