Azureus port forwarding on an Apple extreme basestation

After a hour or so of web search frustration, I worked out how to port forward on a basestation.
First step is to find out what the IP address of the machine is. You can click on the apple in the file menu-about this mac-more info-network. The IP address you are after will look something like that which is highlighted in yellow:


Then open your airport admin utility. Click on configure-then the port mapping tab. Click add and fill out the remain last section of the IP address you copied previously. Make sure the public and private port are both designated as port 6881. In my case the IP address was 172.16.1.2 (see below)


Click OK and make sure you click the UPDATE button in the lower right of the window. This will restart the basestation with port 6881 mapped correctly.



That's it. Open Azureus, use the configuration wizard if you want and enjoy all the green smiley faces!
