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 192.168.1.254.
We will list a series of lines here that will show you exactly how to forward the ports you need to forward. Burnout Revenge requires you to forward the 3658,3659,10070,10080,31800-31899 ports. Go ahead and enter the settings shown above into the Edit Application menu and then click Add Definition.
You should see another page of settings that need to be entered into one of the blank lines on your routers Edit Application page. Go ahead and enter those settings and then click Add Definition.
When you are finished, click the Done button at the bottom of your screen. And that is it! You are done!
