Most ISPs block the default port that Azureus uses. So it is a good idea to change Azureus' port number to something other than the default port. Here's a brief walkthrough on how to do that.
In Azureus click Tools in the menu at the top of your screen. Then click the Options link in the menu that drops down.
In the menu tree on the left hand side of this window Connection should be selected. Pick a random port between 49152 and 65535. Then enter that port into the Incomming TCP/UDP Listen Port box. When you are done, be sure to click the Save button at the bottom of the configuation screen.
Please enter the port you chose for Azureus below.
To configure this router's firewall you need to setup a static IP address on your computer. Take a look at our Static IP Address guide to setup a static ip address. When you are finished setting up a static ip address, please come back to this page and enter the ip address you setup in the Static IP Address box below.
Open a web browser like internet explorer or Netscape. Enter the ip address of your router in the address bar of your browser. In the picture above the address bar has http://www.google.com in it. Just replace all of that with the ip address of your router. By default the ip address should be set to 192.168.1.1.
You should see a box prompting you for your password. Enter your password now. By default your password is admin. Click the Log in button to log in to your router.
Click the Firewall link near the left side of the page.
Click the PCs Privileges link near the top of the page.
Click the New button near the right side of the page.
We will list a series of lines here that will show you exactly how to setup your router's firewall for Azureus. Go ahead and enter the settings shown below into the PC Privileges menu.
And that is it! You are done!
