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.

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 192.168.0.1.

You should see a box prompting you for your username and password. Enter your username and password now. By default the username is admin, and the password is password. Click the Ok button to log in to your router.

Please visit our default username and passsword page, if the username and password shown above did not work for you.

We will list a series of lines here that will show you exactly how to forward the ports you need to forward. Azureus requires you to forward the ports you entered above. Go ahead and enter the settings shown above into the Virtual Server Configuration menu and then click Add This Setting.

Under Security in the left hand menu click Firewall Services.
You should see the following menu.

Click Add to add a service.

Go ahead and name your service. It doesn't really matter what the name is, but something easy to remember would be good. Select tcp or udp under type. If you are unsure of the type just select both. Last put in the Start and Finishing port numbers. If the service only requires one port, put that port number in both the start and the finish box. You may need to setup multiple services, depending upon the number of ports/port ranges the software you want to run requires. Click Save when you have finished.

Now we need to go to the second section to continue setting up our port forwarding. Under Security in the left hand menu click Rules.
Once again you should see the following menu.

Go ahead and click Add in the Outbound or Inbound services section. If you are unsure whether the program you are using will use these ports for inbound or outbound traffic, repeat steps 7 through 9 for both Inbound and Outbound.

Select the service we previously created. Action should be set to ALLOW always. Enter the ip address you want to forward these ports to in Send to LAN Server. If you are forwarding ports so you can run a program on your computer, you should enter the your computers ip address into this box. Wan Users should be set to Any, unless you want to limit who you want to connect to these ports. This would be useful, lets say, if you only wanted your office computer to be able to ftp into your home computer. In that case you would put your office computers ip address in both the start and finish box. Generally log should be set to never, unless of course you want to create a log of network activity.
When you are finished with that configuration go ahead and click Save.

You should see another page of settings that need to be entered into one of the blank lines on your routers Virtual Server Configuration page. Go ahead and enter those settings and then click Add This Setting.
