Problems with seeding torrents

ok im on one particular torrent site and ive downloaded a file very quickly which was about 21 megs and ive only uploaded 288kb and it stopped at 0kb...now im one a few other torrent sites and my download/upload rates are really good and i have no complaints, it seems to be just this one site, i cant upload what ive downloaded,

-why is this? could it be the files are over seeded...
-what changes do i need to make to my utorrent settings in order to get a good upload rate on this site...

ive noticed that at the bottom i have a yellow triangle and it says no incoming connections, i may have a problem with my connection, but my internet is working? the DHT says 43 nodes.

i did a speed test as well.

Your in the wrong forum for this... try the bittorrent forum.

Your line has a firewall of some sort blocking incoming connections. For best results open the wall on the port your using and more people will be able to connect to you.

try to open ports od block the firewall....
