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 :confused:

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.

NAT is... http://en.wikipedia.org/wiki/NAT

anyway you probably just need to use your airport admin utility and port your airport for bittorrents ports. I don't have an airport so idk how but i believe thats your problem. Anyone want to correct or clarify please go ahead.
Benjamin is right. You need to open the port you set in Azureus in your Airport firewall. You can do this in your Admin Utility. There's also a point in your Azureus config helper where you can test the port you've set. Try this before and after and see if it worked.

This might be what you're looking for, from the Airport Admin Utility:

You might also want to open ports in OSX firewall for BT.

Add a new port name and fill in the ranges.

Does it matter what the Private IP address is in the Admin Utility? Yours say 10.0.1.2, but mine say something different, but very close.

That's the internal IP on my house wifi network, the actual IP to the real world is different, as crazzyeddie said you'll need to make sure it matches (it usually does).
