If you don't know what Port Forwarding is yet, you might want to start by reading our What is Port Forwarding guide.

Now we need to know your routers IP address. You can find it a variety of ways.
It's ok if you don't know your Level One WBR-3407a router's internal IP address. You can find it by doing one of the following:
Open a web browser like Internet Explorer or Firefox. Enter the internal 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 internal IP address of your Level One WBR-3407a router. By default the IP address should be set to 192.168.0.1.
If you are having trouble with this guide, then perhaps PFConfig may be your solution. PFConfig is a software tool that will automatically forward ports for your Level One WBR-3407a router to save you time and hassle.

Put a checkmark in the Enable checkbox.
Use the PC (Server) box to choose a computer to forward ports to. This box contains a list of computer names that are visible on your network.
When you are finished, click the Save button.
And that is it! You are done!
Now that you have forwarded ports for any port on the Level One WBR-3407a you should test to see if your ports are forwarded correctly.
