Azureus NAT problem

Hi, I have an Inspiron 700m and a dell true mobile 1184 wireless router. When I use a bit torrent client, Azureus, I can connect but I always have the little yellow smiley face. I do not have a firewall on my laptop or desktop so that cannot be the problem. I think my router is the problem This quote comes from the website: http://azureus.aelitis.com/wiki/index.php/PortForwarding

 

"Smiley faces proviSmiley faces provide info on your torrents. The yellow smiley indicates that while your system can initiate connections with other peers (known as local connections, or L in the torrent's "Details" tab), you cannot receive connections initiated from other peers (known as remote connections, or R). This is almost certainly caused by incorrectly forwarded ports from your router or firewall. You can see the L's and R's in the Details tab of your individual torrent. If you see only L's, you probably have a Port Forwarding problem. Green smileys mean that you have both L and R connections to peers and are connected to the tracker. For more information on what every smiley means, click Help > About Health.

There are other possible causes for a yellow smiley. If you see a green smiley or have seen one with the same router/firewall configuration, then port forwarding may not be the culprit. Run the Tools > NAT/Firewall test. "

 

From this I take that I only can initiate connections with other peers but not recieve connections. I was wondering how I can find an open port or something so I can have the green smiley face which enables me to have faster download speeds. I think I heard something about port forwarding enables me to do this but let me know what you guys have to say. Thanks
