Quick question on bittorrent, i know i know there is alot on this topic but i had troubles finding info. Well im using Azureus and my health is always on the yellow face, in which it says if it is connected with the yellow face icon all the time you may have a NAT problem. What is NAT, i checked and i believe im using it. My setup is an adsl modem connected to airport express which i use my iBook to connect. I believe in airport admin utility it is using a DCHP and NAT connection to assign an ip to connect the internet to multiple computers, i think My main issue is if im using NAT and is it going to affect the speed in which i download. Thanks for your time. Edit: My speed is mostly below swarm average all though i do get near full speed of my 512k net. For eg swarm average speed 50kb my speed 15-25kb mostly.
