I have been getting NAT error (red sad smiley) even after opening up the port through Network settings. Is there any other way to avoid the sad smiley and get some happiness - a green smiley.

Hi! I need some more things to know the best way to help you. Do you hava a router, like an airport or something similar? If yes you'll need to forward the port used by bittorrent (I'll explain you ;-). Let me know what connection you have. Bye!

Hi,

I am using an aiprort express, while my DSL connection is PPoE (username with passowrd and dynamic IP). How do I get to see the port bein used by my Azureus program, i tried several random port numbers like 45551 etc and I still got NAT errors. Later I managed to get a yellow smiley but the download is really really sadly slow.

Thanks.

ok great, now let's take back some green smileys!
1): choose and remember the listening port used in azureus (45551 is ok)
2) Quit Azureus and open airport admin utility, that is located in the utilities folder.
Now enter the setup of your airport express and go to the tab used to map the ports (it's the fourth tab from left)
3) Click add, then write the same port that you've just chosen before both in "public port" and "private port"; in the private ip you have to write the dhcp number assigned to your machine. To know what it is, just open the network preference pane, and enter the airport setup, then click on the TCP/IP tab; the number next to ip address is the one you were looking for. You must write that number in the "private ip" of the previous window. After this, press ok and restart the airport by pressing the right button in the airport admin window.
Now reopen azureus and the green smileys should return!
This link could be useful for you to understand what is all about.

That's all! Let me know if you have any problem doing this procedure. Bye!

Hi,

thanks for the reply. did exactly as you told , even added port 45551 in the allowed open port list in the mac firewall and i get a red sad smiley in azureus along with the NAT error message and this message opn start up-

ERROR, unable to bind TCP incoming server socket to 45551 Can't assign requested address

Looks like green smileys are really meant for me - just wish there was an easy torrent software like Bit Comet for Mac OS X ((

try this:

open azureus and go to this web page in safari:

https://grc.com/x/portprobe=45551

tell me what the web page says then.
In this way we are sure if bittorrent port is properly mapped.

You may also try to disable temporarily the system firewall. There is also a nat test in azureus, just in the "azureus" command cascading window.
